Yes, the Air Lift RIDE CONTROL KIT 59526 (Part #BBCG59526) is designed to fit the 2002-2006 Chevrolet Avalanche 2500.
The Air Lift RIDE CONTROL KIT 59526 (Part #BBCG59526) fits the following vehicles: 2002-2006 Chevrolet Avalanche 2500; 1996-2002 Chevrolet Express 1500; 1996-2002 Chevrolet Express 2500; 1970-1974 Chevrolet G10 Van; 2000-2010 Chevrolet Suburban 2500; 2002-2014 Ford E-150; 1975-1978 GMC G15; 1996-2002 GMC Savana 1500; 1996-2002 GMC Savana 2500; 2000-2009 GMC Yukon XL 2500. Always verify your specific year, make, and model before ordering.
The Air Lift RIDE CONTROL KIT 59526 (Part #BBCG59526) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, Air Lift part number 59526 is compatible with 2000 and up 3/4 Ton Suburban and Avalanche models. However, these models mount the air springs behind the axle, unlike most other vehicles which mount forward of the axle. This is a critical fitment difference that must be observed during installation.
Yes, Air Lift part number 59526 is compatible with 1995 and older Chevrolet and GMC vans. These vehicles require a self-tapping frame bolt in the upper forward mounting hole on the passenger side only. Drill a 5/16" hole (no larger) for the self-tapper, but do not install it at this time. All other attachments use the standard 3/8" x 5" bolts.
Yes, Air Lift part number 59526 is compatible with Ford vans and Suburbans. These vehicles have C-section type frame rails and require 3/8"-16 x 1.5" washer head frame bolts instead of the standard 3/8" x 5" bolts. The oversized washers are not necessary for these vehicles.
Air Lift recommends checking with your vehicle dealer before installing this load assist product if your vehicle is equipped with a rear brake proportioning valve, as any type of load assist product could affect brake performance. If your vehicle does not have a rear brake proportioning valve or is equipped with an anti-lock type brake system, installation will have no effect on brake system performance.
You must have a minimum of 6 inches of clearance between the tire and the outside of the frame rail to provide adequate space for the air spring when fully inflated. This measurement should be taken during the ride height determination phase before beginning installation.
The maximum inflated diameter of the air spring is 4.5 inches. You must check that nothing is rubbing against the air spring within this diameter, including the frame, suspension components, or any other vehicle parts.
Required tools include: a drill with a 3/8" drill bit (with at least 4.25" effective length for boxed frame vehicles), a 5/16" drill bit, a 7/16" open end wrench, a standard tube cutter or sharp knife for cutting air lines, a center punch, and an open end wrench for tightening the lower mounting bolt. The kit includes an Air Lift installation tool designed to simplify correct mounting height and alignment.
The kit includes: upper and lower brackets, one installation tool, 1/2" flat washers, 1/2" HHCS bolts, a Pal nut (flange down), nylon nuts, a 3/8" U-bolt with flat washers and nylon lock nuts, 3/8"-16 x 5" bolts, 3/8" flat washers, oversized flat washers, 3/8" nylon lock nuts, a swivel elbow fitting, air lines, tie straps or clips, self-tapping screws, and a rubber washer for the inflation valve. Specific fastener quantities and applications are detailed in the installation sections.
Ride height is defined as the distance between the bottom edge of the fenderwell to the center point of the wheel with the vehicle at the desired height without a load. Measure this distance before beginning installation and record it. All Air Lift kits are designed to be installed and operate at normal ride height. After measuring, jack up the rear of the vehicle or raise it on a hoist, then raise the axle or lower the frame until the leaf spring is at ride height in the unloaded condition.
The manual does not specify whether the battery must be disconnected. Contact Air Lift technical support at 1-800-248-0892 Ext. 2 for guidance specific to your vehicle.
For most vehicles, mount the bracket assembly forward of the axle. However, 2000 and up 3/4 Ton Suburban and Avalanche models must mount behind the axle. The preassembled bracket/tool unit is set on the leaf spring at the appropriate location, with the hook end of the lower bracket placed over the existing U-bolt or spring retainer.
Place the upper bracket onto the threaded end of the tool and rest it on the bottom Pal nut (flange down). Thread a nylon nut onto the tool to hold the bracket in place. Attach the lower bracket to the bottom of the installation tool using a 1/2" flat washer and 1/2" x 7/8" bolt, leaving it just loose enough to adjust in and out. Set the preassembled unit on the leaf spring, then use the nuts on the threaded portion of the tool to adjust the upper bracket up and down so the flanges are flat against the frame rail and all four mounting holes are on the flat middle section of the frame rail. Do not place holes directly on the radius bend of the frame.
Torque the lower bracket U-bolt to 16 ft-lbs. The U-bolt is secured to the leaf spring using the provided flat washers and lock nuts.
Yes, drilling is required. You must drill 3/8" holes through the frame rail for the upper bracket mounting bolts. For boxed frame vehicles, you will need a drill bit with at least 4.25" effective length. You must also drill a 5/16" hole for the inflation valve. Before drilling any frame holes, ensure all hydraulic lines, gas lines, and electrical wires have been moved aside on both sides of the frame rail.
Yes, you must cut the air line in two equal lengths using a standard tube cutter, razor blade, or very sharp knife. A clean square cut is essential to prevent leaks. Cut off excess air line squarely before installing it into the fitting.
Torque all upper bracket frame bolts to 20 ft-lbs. This applies to all four mounting holes after they have been drilled and the bolts installed.
Torque the upper nylon nut to 4 ft-lbs. Do not over tighten.
Install the elbow fitting finger tight plus 1 1/2 turns. Use a 7/16" open end wrench, being careful to tighten on the metal hex nut only. Do not over tighten. The fitting is precoated with thread sealant.
Cut the air line squarely. Push and slightly turn the cut end of the air line into the fitting as far as it will go. This is a self-locking fitting. When properly seated, a click can be heard or felt. The air line should go in 9/16".
Route the air line along the frame from the inflation valve location to the air springs. Use tie straps or provided clips and self-tapping screws to attach the air line to the frame rail. It is not necessary to drill a hole for the self-tapping screws; simply drive the screw through the frame section. Attach the air line to the chassis with the provided plastic straps. Keep the air line at least 12 inches from the exhaust system to prevent melting.
Select a location for the inflation valves in the rear bumper area or rocker panel flange, ensuring that each valve will be protected and accessible with an air hose. Drill a 5/16" hole for the inflation valve and mount as illustrated in the manual. The rubber washer goes on the outside for weather sealing.
You must maintain a minimum of 5 p.s.i. air pressure at all times. The minimum air pressure keeps the air spring in shape, ensuring that it will move throughout its travel without rubbing or wearing on itself. Failure to maintain correct minimum pressure voids the warranty.
The maximum air pressure is 100 p.s.i. However, the air pressure actually needed depends on your load and vehicle GVWR, which may be less than 100 p.s.i. Check your vehicle owner's manual and do not exceed the maximum load listed for your vehicle. Do not exceed your vehicle's Gross Vehicle Weight Rating (GVWR).
No. Do not try to inflate the air sleeves until they have been properly secured to the vehicle. Compressed air can cause injury and damage to the vehicle and parts if not handled properly.
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. If you need to raise the vehicle by the frame, make sure the system is at minimum pressure (5 p.s.i.) to reduce tension on the suspension and brake components.
After inflating to 60 p.s.i., check all fittings and the inflation valve core with a solution of 1/5 dish soap to 4/5 water for leaks. Check that you have clearance all around the air spring at its fully inflated diameter (4.5"). Verify that the sleeve rolls back down over the bottom piston after the vehicle is lowered. Recheck air pressure after 24 hours; a 2-4 p.s.i. loss after initial installation is normal. If pressure has dropped more than 5 p.s.i., retest for leaks with the soapy water solution.
Check the air pressure weekly. Always maintain at least 5 p.s.i. air pressure. Recheck air pressure after 24 hours of initial installation; a 2-4 p.s.i. loss is normal. If pressure drops more than 5 p.s.i., use a soapy water solution to check all air line connections and the inflation valve core for leaks.
Inflate your air springs to 60 p.s.i. before adding the payload. After the vehicle is loaded, adjust your air pressure to level the vehicle and for ride comfort. When increasing load, always adjust the air pressure to maintain the 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.
Yes. When carrying a payload, it is helpful to increase the tire inflation pressure in proportion to any overload condition. Air Lift recommends a 2 p.s.i. increase above normal (not to exceed tire manufacturer maximum) for each 100 lbs. total overload on the axle.
If the air springs are properly installed and maintained, they can last indefinitely. Proper maintenance includes checking air pressure weekly, maintaining at least 5 p.s.i. minimum pressure, adjusting pressure to maintain normal ride height under load, and ensuring the air spring is not the suspension limiter in compression or extension.
No. Adding air springs will not change the weight ratings (GAWR, GCWR, and/or GVWR) of your vehicle. Exceeding the GVWR is dangerous and voids the Air Lift warranty. You must not exceed your vehicle manufacturer's maximum Gross Vehicle Weight Rating.
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, though it requires significant effort.
Air Lift 59526 fits cars, vans, light trucks and motorhomes. Special fitment rules apply: 2000+ 3/4 Ton Suburban/Avalanche mount behind the axle; 1995 and older Chevy/GMC vans require a self-tapping bolt on the passenger side; Ford vans/Suburbans need 3/8"-16 x 1.5" washer head bolts. Check with your dealer if your vehicle has a rear brake proportioning valve. You need minimum 6" clearance between tire and frame rail.
You need a drill with 3/8" and 5/16" bits (3/8" bit requires 4.25" length for boxed frames), 7/16" open end wrench, tube cutter or sharp knife, center punch, and an open end wrench for the lower bolt. The kit includes an installation tool to ensure correct mounting height and alignment.
Yes. You must drill 3/8" holes through the frame rail for the upper bracket (4.25" bit length required for boxed frames) and a 5/16" hole for the inflation valve. Before drilling, move all hydraulic lines, gas lines, and electrical wires aside on both sides of the frame rail.
Lower bracket U-bolt: 16 ft-lbs. Upper bracket frame bolts: 20 ft-lbs (all four holes). Upper nylon nut on air spring: 4 ft-lbs. Elbow fitting: finger tight plus 1½ turns using 7/16" wrench on the hex nut only. Do not over tighten.
Maintain minimum 5 p.s.i. at all times. Maximum is 100 p.s.i., but actual pressure needed depends on your load and vehicle GVWR (which may be less). Start at 60 p.s.i. before loading, then adjust to maintain normal ride height under load. Do not exceed your vehicle's GVWR.
Inflate to 60 p.s.i. and check all fittings and valve core with soapy water (1/5 dish soap, 4/5 water) for leaks. Verify 4.5" clearance around the fully inflated air spring. Confirm the sleeve rolls back down over the piston when lowered. Recheck pressure after 24 hours; 2-4 p.s.i. loss is normal. If loss exceeds 5 p.s.i., retest for leaks.
Check air pressure weekly. Maintain minimum 5 p.s.i. always. Before loading, inflate to 60 p.s.i., then adjust pressure to maintain normal ride height under load. For each 100 lbs. overload, increase tire pressure 2 p.s.i. (not exceeding tire max). If air leak suspected, use soapy water to test connections and valve core before removing the sleeve.
Add air pressure until the sleeve 'pops' back over the piston. Do not exceed 100 p.s.i. If the sleeve fails to roll back down, this indicates insufficient air pressure to support the load or suspension geometry issue.
A 2-4 p.s.i. loss after initial installation is normal. If pressure has dropped more than 5 p.s.i., use a solution of 1/5 dish soap to 4/5 water to check all air line connections and the inflation valve core for leaks. Test each connection and the valve core thoroughly. If a leak is found, reseat the air line in the fitting or tighten the valve core.
The maximum inflated diameter of the air spring is 4.5 inches. If rubbing is occurring, you may have insufficient clearance. Check that you have at least 6 inches of clearance between the tire and the outside of the frame rail. Verify the air spring is properly aligned by inflating to approximately 10 p.s.i. and using the slotted adjustment in the lower bracket to center the air spring so there is a symmetrical cushion of air around the lower base. Rubbing against another component voids the warranty.
Your vehicle is not level. Raise the air pressure in the air springs to correct this problem and level the vehicle. Adjust pressure up or down to achieve level. If the vehicle is heavier on one side due to loads such as water, fuel, or appliances, it may be necessary to maintain different pressures on each side; as much as a 50 p.s.i. difference is not uncommon.
A rough and harsh ride may be due to either too much pressure or not enough pressure. Try different pressures to determine the best ride comfort. Start with the vehicle level or slightly above, and adjust pressure up and down to find the best ride. If you suspect the air bags have bottomed out, increase the pressure.
Stability issues include roll control, bounce, dive during braking, and sponginess. Tuning out these problems usually requires an increase in pressure. Adjust the air pressure up to reduce movement and improve stability. Stability should be the priority, as it translates into safety; you may need to sacrifice a perfectly level and comfortable ride for better stability.
If the front of the vehicle dives while braking, increase the pressure in the front air bags if equipped. This will improve stability during braking.
