Yes, the Air Lift AIR LIFT 1000 air spring kit. 60743 (Part #BBCG60743) is designed to fit the 1996-2002 Toyota 4Runner.
The Air Lift AIR LIFT 1000 air spring kit. 60743 (Part #BBCG60743) fits the following vehicles: 1996-2002 Toyota 4Runner. Always verify your specific year, make, and model before ordering.
The Air Lift AIR LIFT 1000 air spring kit. 60743 (Part #BBCG60743) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The Air Lift 1000 is an air spring kit designed to provide load support for the rear suspension of a 2011 Toyota Sequoia 4WD. It works by adding pressurized air springs that work alongside the factory coil springs to help level the vehicle and improve ride quality when carrying loads. The system allows you to adjust air pressure to maintain proper ride height and handling.
Kit 60743 (MN-408) is specifically designed for the 2011 Toyota Sequoia 4WD. If you have a different model year, generation, or drivetrain configuration, you will need to verify compatibility with Air Lift Company before purchasing. Contact Air Lift customer service at (800) 248-0892 or visit www.airliftcompany.com to confirm fitment for your vehicle.
No. Installing air springs will not change the weight ratings (GAWR, GCWR, and/or GVWR) of your vehicle. The installation of this kit does not alter the Gross Vehicle Weight Rating or payload. You must continue to check your vehicle's owner's manual and not exceed the maximum load listed for your vehicle. Exceeding the GVWR is dangerous and voids the Air Lift warranty.
The manual does not provide a complete tool list. However, based on the installation steps, you will need: a jack and safety stands, a drill with a 9/16" bit (for the lower spring seat hole) and a 5/16" bit (for the inflation valve hole), pliers (for tightening air line clamps), a wrench (for tightening swivel fittings), a valve core tool (for checking the inflation valve), and an air compressor to inflate and adjust the air springs. Contact Air Lift at (800) 248-0892 if you need a detailed tool list.
Yes. The coil springs must be removed for installation. You will need to jack up the rear of the vehicle and support the frame with safety stands, then detach the shock absorbers at the lower shock mount, detach the panhard rod at the lower axle mount, disconnect any rear anti-sway bar links if present, and carefully lower the axle until the coil springs are free. Be careful not to strain the brake lines; disconnect brake line brackets if necessary before removing the coil springs.
There are three types: Type 1 has no jounce bumper at the top spring seat with a large hole—insert the protector and cylinder with the stem up. Type 2 has a small jounce bumper (approximately 3" long) at the top of the coil spring—unbolt and discard it, then drill a 9/16" hole in the lower spring seat and insert the cylinder and protector with the stem down. Type 3 has a large jounce bumper at the top of the coil spring—trim the jounce bumper as specified in the manual's figure 4, then drill a 9/16" hole in the lower spring seat and insert the cylinder with the stem down.
Tee Air Line routing uses a single tee fitting with one inflation valve and is best for vehicles loaded evenly from side to side. Dual Air Line routing uses two separate inflation valves (one for each side) and should only be used if the vehicle will have unbalanced side-to-side loading—for example, considerably more load on the left side than the right, or vice versa. Choose the option that matches your intended use.
You need to drill two types of holes: a 9/16" hole in the lower spring seat for the air cylinder (required for Type 2 and Type 3 jounce bumper configurations), and a 5/16" hole for the inflation valve. The location of the 9/16" hole should be marked using the center template circles provided in the manual. The 5/16" hole for the inflation valve can be drilled in the gas cap well, trunk, rear bumper, fender flange, or behind the license plate, depending on where you choose to mount the valve.
Yes. If your vehicle has a large jounce bumper at the top of the coil spring (Type 3), it will be necessary to trim the jounce bumper as specified in figure 4 of the manual. After trimming, center the template, mark, and drill a 9/16" hole in the lower spring seat for hose access to the cylinder, then insert the cylinder with the stem down.
Use this procedure for all air line connections: (1) Slide the air line clamp onto the air line. (2) Push the air line over the barbed stem, covering all the barbs. (3) Compress the ears on the air line clamp with pliers and slide it forward to fully cover the barbed section. Repeat this procedure for each connection point. Leave sufficient air line slack to prevent any strain on fittings during axle motions.
Keep the air line at least 8 inches from the exhaust system to prevent it from melting. Route the air line along the cross member and upper spring seat to the air cylinder, then through the spring seat and protector. For the main line from the tee to the inflation valve, route it along the frame and attach it with plastic straps. Leave sufficient slack to prevent any strain on fittings during axle motions. If a heat shield is included in the kit, install it. If there is no heat shield but one is required, call (800) 248-0892.
Select a location for the inflation valve that is protected and accessible with an air hose. Options include the gas cap well, the trunk, the rear bumper, the fender flange, or behind the license plate. Drill a 5/16" hole at your chosen location. The rubber washer included with the valve is for outside weather seal. For Dual Air Line routing, select locations for both valves in the rocker panel flange or rear bumper.
After installation, reattach all components that were disconnected during preparation: (1) Reconnect brake lines to mounting brackets on the rear axle. (2) Reconnect the swaybar link if it was removed. (3) Reconnect the panhard rod. (4) Reconnect the shock absorbers. Ensure all fasteners are properly tightened.
The minimum air pressure is 5 PSI, which must be maintained at all times to keep the air spring in shape and ensure it moves throughout its travel without rubbing or wearing on itself. The maximum air pressure is 35 PSI. Never inflate beyond 35 PSI. The actual pressure needed depends on your load and GVWR. Always maintain normal ride height and adjust pressure as necessary to attain normal ride height for optimal ride and handling.
Inflate the air springs to 35 PSI. Spray all connections and the inflation valves with a solution of 1 part liquid dish soap and 4 parts water. Spot leaks by looking for bubbles in the soapy water. After the test, deflate the springs to the minimum pressure required to restore the system to normal ride height (do not deflate below 5 PSI). Check the air pressure again after 24 hours. A 2–4 PSI loss after initial installation is normal. If the loss is more than 5 PSI, retest for leaks and fix any problems before road testing.
Inflate the air springs to 35 PSI and ensure there is at least 1/2" clearance around each bellow, away from anything that might rub against them. Be sure to check the tire, brake drum, frame, shock absorbers, and brake cables. Additionally, ensure there is sufficient clearance from any heat sources—at least 6" for air springs and air lines. If any part shows signs of rubbing or abrasion during the 30-day or 500-mile test, identify and move the source if possible, or remount the air spring if relocation is not possible.
Before road testing, complete these checks: (1) Clearance test—inflate to 35 PSI and ensure at least 1/2" clearance around each bellow from tires, brake drums, frame, shock absorbers, and brake cables. (2) Leak test—inflate to 30 PSI and check all connections with soapy water solution; all leaks must be eliminated before road testing. (3) Heat test—ensure at least 6" clearance from heat sources. (4) Fastener test—recheck all bolts for proper torque. (5) Road test—inflate to 25 PSI (30 PSI if loaded), drive 10 miles, and recheck for clearance, loose fasteners, and air leaks.
Check the air pressure weekly. Always maintain normal ride height. Never inflate beyond 35 PSI. When increasing load, always adjust the air pressure to maintain normal ride height. Increase or decrease pressure from the system as necessary to attain normal ride height for optimal ride and handling. Remember that loads carried behind the axle (including tongue loads) require more leveling force (pressure) than those carried directly over the axle.
If the air springs are properly installed and maintained, they can last indefinitely. Proper maintenance includes checking air pressure weekly, maintaining normal ride height, never inflating beyond 35 PSI, and addressing any air leaks promptly using a soapy water solution to identify the source before deflating and removing the spring.
Recheck all bolts for proper torque after the initial installation. Re-torque after 100 miles. Additionally, perform a 30-day or 500-mile test (whichever comes first) to recheck the air spring system and ensure all fasteners remain tight. If any part shows signs of rubbing or abrasion, identify and move the source if possible, or remount the air spring if necessary.
Yes, the vehicle can be lifted on a hoist for short-term service work such as tire rotation or oil changes. However, if the vehicle will be on the hoist for a prolonged period of time, support the axle with jack stands to take the tension off the air springs. Use of on-board leveling systems does not require deflation or disconnection. If you need to raise the vehicle by the frame, make sure the system is at minimum pressure (5 PSI) to reduce tension on the suspension and brake components.
Always add air to the springs in small quantities, checking the pressure frequently. Cylinders require less air volume than a tire and inflate quickly. Start with the vehicle level or slightly above. When in doubt, always add air. Inflate your air springs to 30 PSI before adding the payload; this allows the air cylinder to properly mesh with the coil spring. After the vehicle is loaded, adjust your air pressure down to level the vehicle and for ride comfort. Never exceed 35 PSI maximum inflation pressure.
Use a soapy water solution to check all air line connections and the inflation valve core before deflating and removing the spring. Spray all connections and valves with a solution of 1 part liquid dish soap and 4 parts water. Look for bubbles to spot leaks. If you find a leak at a swivel fitting, check the air line connection by deflating the spring, removing the line, trimming 1" off the end with a clean square cut, and reinserting it. If the threaded connection leaks, tighten the swivel fitting another 1/2 turn. If it still leaks, deflate, remove the fitting, re-coat the threads with thread sealant, and reinstall by hand tightening as much as possible, then use a wrench for an additional two turns.
Check the valve core by tightening it with a valve core tool. If the leak persists, check the air line by removing it from the barbed fitting. Cut the air line off a few inches in front of the fitting and use pliers or vice grips to pull or twist the air line off the fitting. Do not cut off the air line completely, as this will usually nick the barb and render the fitting useless. If these steps do not resolve the problem, call Air Lift customer service at (800) 248-0892.
Inspect the air lines to be sure none are pinched. Tie straps may be too tight. Loosen or replace the strap and replace leaking components. Look for a kink or fold in the air line and reroute as needed. Ensure sufficient air line slack to prevent any strain on fittings during axle motions. Keep the air line at least 8 inches from the exhaust system to prevent melting.
If the vehicle's headlights are shining into the trees or the vehicle is leaning to one side, it is not level. Raise the air pressure to correct either of these problems and level the vehicle. It may be necessary to maintain different pressures on each side of the vehicle. Loads such as water, fuel, and appliances will cause the vehicle to be heavier on one side. If you are using Dual Air Line routing, you can adjust each side independently. Always maintain normal ride height and adjust pressure as necessary.
If the vehicle has a rough or harsh ride, it may be due to either too much pressure or not enough. Try different pressures to determine the best ride comfort. Stability issues such as roll control, bounce, dive during braking, and sponginess usually require an increase in pressure. Stability translates into safety and should be the priority, meaning you may need to sacrifice a perfectly level and comfortable ride. Adjust the pressure up and down to find the best ride.
If it is ever suspected that the air bags have bottomed out, increase the pressure. Bottoming out occurs when the air spring compresses completely and loses its support function. Increasing pressure will prevent this condition. If the front of the vehicle dives while braking, increase the pressure in the front air bags if equipped. Always maintain sufficient pressure to support the load and maintain normal ride height.
If the vehicle rocks and rolls, adjust the air pressure to reduce movement. Increasing pressure will improve stability and reduce body roll. Stability issues include roll control, bounce, dive during braking, and sponginess. Tuning out these problems usually requires an increase in pressure. Stability translates into safety and should be the priority.
If any part shows signs of rubbing or abrasion, identify the source and move it if possible. If it is not possible to relocate the cause of the abrasion, the air spring may need to be remounted. If professionally installed, consult the installer for service. Ensure at least 1/2" clearance around each bellow, away from anything that might rub against them, including the tire, brake drum, frame, shock absorbers, and brake cables.
No. Air pressure can be adjusted with any type of compressor as long as it can produce sufficient pressure to service the springs. Even a bicycle tire pump can be used, but it requires significant effort. Most users prefer an electric air compressor for convenience and speed.
When carrying a payload, it will be helpful to increase the tire inflation pressure in proportion to any overload condition. Air Lift recommends a 2 PSI increase above normal for each 100 lbs of additional load on the axle. This helps maintain proper tire performance and vehicle stability when carrying extra weight.
Air Lift Company provides a limited lifetime warranty to the original purchaser of its Load Support products, covering defects in workmanship and materials when used on cars and trucks as specified by Air Lift Company and under normal operating conditions. The warranty is subject to requirements and exclusions set forth in the full Limited Warranty and Return Policy available online at www.airliftcompany.com/warranty. Failure to maintain correct minimum pressure, bottoming out, over-extension, or rubbing against another component will void the warranty.
Yes, kit 60743 (MN-408) is designed specifically for the 2011 Toyota Sequoia 4WD. For other model years or configurations, contact Air Lift at (800) 248-0892 to verify fitment.
Yes. You must drill a 9/16" hole in the lower spring seat (required for Type 2 and Type 3 jounce bumper configurations) and a 5/16" hole for the inflation valve. Use the drilling template provided in the manual, printed at 100% scale.
The maximum air pressure is 35 PSI. Never inflate beyond this pressure. The minimum pressure is 5 PSI and must be maintained at all times. Actual pressure needed depends on your load and GVWR.
Ensure at least 1/2" clearance around each bellow from tires, brake drums, frame, shock absorbers, and brake cables. Maintain at least 6" clearance from heat sources. Check these clearances at 35 PSI before road testing.
First, check the air line connection: deflate the spring, remove the line by pulling the collar against the fitting and pulling firmly on the air line, trim 1" off the end with a clean square cut, and reinsert the air line into the push-to-connect fitting. If it still leaks, tighten the swivel fitting another 1/2 turn. If it continues to leak, deflate the spring, remove the fitting, re-coat the threads with thread sealant, and reinstall by hand tightening as much as possible, then use a wrench for an additional two turns.
Check the valve core by tightening it with a valve core tool. If the leak persists, check the air line by removing it from the barbed fitting. Cut the air line a few inches in front of the fitting and use pliers or vice grips to pull or twist the air line off. Do not cut the air line completely, as this will nick the barb and render the fitting useless. If the problem continues, call Air Lift at (800) 248-0892.
Inspect the air lines and loosen or replace any tie straps that are too tight. Look for kinks or folds in the air line and reroute as needed. Ensure sufficient air line slack to prevent strain on fittings during axle motions. Keep the air line at least 8 inches from the exhaust system to prevent melting.
Inspect the air line for holes and cracks and replace as needed. If the problem persists after replacing the air line and checking all connections, it may be caused by a failed air spring (either a factory defect or an operating problem). Call Air Lift at (800) 248-0892 for assistance.
If the headlights are shining into the trees or the vehicle is leaning to one side, raise the air pressure to level the vehicle. It may be necessary to maintain different pressures on each side if loads such as water, fuel, or appliances cause the vehicle to be heavier on one side. Adjust pressure as needed to maintain normal ride height.
If the ride is rough or harsh, it may be due to either too much or too little pressure. Try different pressures to determine the best ride comfort. If the vehicle rocks and rolls excessively, increase the pressure to improve stability. Stability issues such as roll control, bounce, dive during braking, and sponginess usually require an increase in pressure. Stability should be the priority over a perfectly level and comfortable ride.
If the air springs have bottomed out (compressed completely), increase the pressure immediately. Bottoming out indicates insufficient pressure to support the load. Increase pressure to prevent this condition and maintain normal ride height. If the front of the vehicle dives while braking, increase the pressure in the front air bags if equipped.
Identify the source of the rubbing or abrasion and move it if possible. Ensure at least 1/2" clearance around each bellow from tires, brake drums, frame, shock absorbers, and brake cables. If the source cannot be relocated, the air spring may need to be remounted. If professionally installed, consult the installer for service.
