Yes, the Air Lift SlamAir for Lowered trucks. 59210 (Part #BBCG59210) is designed to fit the 2004-2014 Ford F-150.
The Air Lift SlamAir for Lowered trucks. 59210 (Part #BBCG59210) fits 2004-2014 Ford F-150 models. The 2014 model year is the last year covered by this part number. For newer models, check for an updated version.
The Air Lift SlamAir for Lowered trucks. 59210 (Part #BBCG59210) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The SlamAir air spring kit (part number 59210, model MN-686) is an air suspension system designed for lowered Ford F-150 trucks. It uses pneumatic air springs to support the vehicle's weight and maintain a custom ride height. The kit allows you to adjust ride height and load-carrying capacity by adjusting air pressure, and can help level the vehicle when loaded.
The SlamAir kit (59210) is designed for Ford F-150 trucks that have been lowered. However, the manual states this is a universal kit for custom applications and cannot guarantee fit on every vehicle, as fitment depends on the type of lowering kit installed and optional equipment present. You may need to modify or weld the upper bracket depending on your specific lowering setup. Contact Air Lift customer service at (800) 248-0892 to confirm compatibility with your truck's year and lowering configuration.
Yes. The manual includes specific installation instructions for shackle drop installations (also called shackle hanger installations). The L-bracket installation process differs from flipped axle applications, but the kit is designed to work with both types of lowering. Follow the "For Shackle Drop Installations" section on page 8 of the manual.
Yes. The manual includes specific installation instructions for flipped axle lowered applications. The L-bracket installation process differs from shackle drop installations, but the kit is designed to work with both types of lowering. Follow the "For Flipped Axle Lowered Applications" section on page 7 of the manual.
The kit requires a minimum of 5 inches of clearance between the frame and the tire when the air spring is fully inflated. This clearance must be measured at the custom ride height of the lowered vehicle.
The manual states that any type of load assist product could affect brake performance on vehicles equipped with a rear brake proportioning valve. Air Lift recommends checking with your vehicle's dealer before installing this product. If your vehicle does not have a rear brake proportioning valve or is equipped with an anti-lock brake system, installation will have no effect on brake system performance.
No. The installation of the SlamAir kit does not alter the Gross Vehicle Weight Rating (GVWR) or payload of your vehicle. You must check your vehicle's owner's manual and never exceed the maximum load listed for your truck. The kit helps distribute weight more evenly but does not increase the vehicle's weight-carrying capacity.
Required tools include: hoist or floor jacks, 2 safety stands, safety glasses, torque wrench, ratchet with 3/8", 9/16", and 1/2" deep well sockets, very sharp 3/8" and 9/16" drill bits, 3/8" nut driver, 1/2", 3/4", 7/16", and 1-1/16" open-end or box wrenches, heavy-duty drill, hose cutter or sharp knife, air compressor or compressed air source, and spray bottle with dish soap and water solution.
The kit includes: 2 air springs (part 58482), 1 installation tool with nut (10549), 2 upper brackets (07940), 2 lower brackets (03616), 2 clamp bars (01426), 2 U-bolts (10583), 2 3/4" nylon nuts (18454), 12 3/8" flat washers (18444), 8 3/8" oversized flat washers (18447), 12 3/8" nyloc nuts (18435), 2 1/2"-13 x 7/8" bolts (17124), 2 1/2" flat washers (18414), 8 3/8"-16 x 4" bolts (17145), 2 swivel air fittings (21848), 4 centering pin spacers (13400), 2 L-brackets (10867), 4 short frame spacers (13231), 4 long frame spacers (13399), 1 air line assembly (20086), 6 zip ties (10466), 2 valve caps (21230), 2 5/16" flat washers (18405), 2 rubber washers (21234), 2 star washers (18411), and 4 5/16" hex nuts (21233).
The manual recommends replacing the U-bolts with new ones (not provided in the kit) when installing the L-brackets. This is noted as a recommendation rather than a requirement, but Air Lift advises new U-bolts for both shackle drop and flipped axle installations.
Custom ride height is the distance between the bottom edge of the wheel-well and the center of the hub when the vehicle is in its lowered condition. To determine it: (1) remove unusual loads and examine the vehicle from the side on a level surface, (2) if necessary, use a jack to raise the rear end so the vehicle achieves the desired lowered ride height. The vehicle must be at this custom ride height during bracket positioning and upper bracket attachment.
The manual does not mention disconnecting the battery as part of the installation procedure.
Yes. The manual states to raise the vehicle and remove the wheels as the first step in the installation process.
Before drilling, you must check the back side of the frame for clearance issues such as brake lines, gas lines, and electrical lines. All obstacles need to be temporarily relocated to clear the area. The brake line and exhaust hanger on the inside of the frame behind the axle may need to be relocated permanently because of the mounting hardware. Additionally, maintain a distance of 1.25" above the upper bracket for valve clearance, and if needed, it may be necessary to bend the flange on the inner wheel well seam to obtain this clearance.
Yes. You must drill 3/8" holes through the frame for the upper bracket mounting hardware. Additionally, the inside holes must be enlarged from 3/8" to 9/16" to accommodate frame spacers. You also need to drill a 5/16" hole for the inflation valve. A heavy-duty drill with very sharp 3/8" and 9/16" drill bits is required.
Yes. The air line assembly must be cut in two equal lengths. When cutting, use a hose cutter, razor blade, or sharp knife to make a clean, square cut. Do not use wire cutters or scissors, as these tools may flatten or crimp the air line, causing leaks around the O-ring seal inside the elbow fitting. You will also cut off air line leaving approximately 12" of extra when connecting to the air fitting.
The manual states that the brake line and exhaust hanger on the inside of the frame behind the axle may need to be relocated permanently because of the mounting hardware that attaches the upper bracket to the frame. For clearance when drilling the frame, it will be necessary to unbolt and move the brake line bracket on the driver side, and possibly the exhaust hanger on the passenger side. Whether relocation is permanent depends on your specific vehicle configuration.
It may be necessary to bend the flange on the inner wheel well seam to obtain the required 1.25" clearance above the upper bracket for air fitting clearance. This is not required on all vehicles but should be checked during positioning of the upper bracket.
The U-bolt attaching the lower bracket to the leaf spring should be torqued to 16 ft/lbs.
The lower mounting bolt of the air spring should be tightened to a maximum of 15 ft/lbs.
The nylon nut on the upper thread post of the air spring should be tightened to 4 ft/lbs. Do not overtighten.
The swivel air fitting should be hand-tightened first, then sealed by tightening one and a half turns with a 7/16" open-end wrench, being careful to tighten on the metal hex nut only. Do not overtighten. The fitting is pre-coated with sealant.
The leaf spring U-bolts should be torqued to stock specifications for your vehicle. The manual does not provide a specific torque value, as this varies by vehicle model and year.
The manual does not provide a specific torque value for the upper bracket mounting bolts. The instruction states to "tighten securely" after installing the 3/8"-16 x 4" bolts with frame spacers.
You must drill a 5/16" hole to install the inflation valves.
Popular locations for the inflation valves are: (1) the wheel well flanges, (2) license plate recess in bumper, (3) under the gas cap access door, or (4) through the license plate itself. Whatever location you choose, make sure there is enough clearance around the inflation valves for an air chuck to be easily applied.
Insert the air line into the 90° swivel fitting until it bottoms out. Approximately 9/16" of air line should be in the fitting. This is a push-to-connect fitting.
Route the air line along the frame to the air fitting on the air spring. Keep at least 6" of clearance between the air line and heat sources such as exhaust pipes, muffler, or catalytic converter. Avoid sharp bends and edges. Use the plastic tie straps to secure the air line to fixed, non-moving points along the chassis. Tie straps should be tight but not pinch the air line. Leave at least 2" of slack to allow for any movement that might pull on the air line.
Keep at least 6" of clearance between the air line and heat sources such as exhaust pipes, muffler, or catalytic converter.
The minimum air pressure should be maintained at all times. The manual specifies a minimum of 10 PSI. 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 will void the warranty.
Never inflate the air springs beyond 100 PSI. Although the air springs are rated at a maximum inflation pressure of 100 PSI, the air pressure actually needed is dependent on your load and GVWR. Always maintain normal ride height and never exceed your vehicle's maximum gross vehicle weight rating.
Do not try to inflate the air springs until they have been properly secured to the vehicle. During alignment, inflate the air spring to approximately 10 PSI with the bottom of the air spring still loose. After checking for leaks at 30 PSI, deflate the springs to the minimum pressure required to restore the custom ride height, no less than 10 PSI.
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 in order to take the tension off of the air springs.
If it becomes necessary to raise the vehicle by the frame, make sure the system is at a minimum pressure of 10 PSI to reduce tension on the suspension and brake components. Use of on-board leveling systems does not require deflation or disconnection.
Before operating, perform these checks: (1) Clearance test — inflate air springs to 60 PSI and ensure at least 1/2" clearance from anything that might rub (tire, brake drum, frame, shock absorbers, brake cables). (2) Leak test — inflate to 30 PSI and check all connections for leaks. (3) Heat test — ensure at least 6" clearance from heat sources. (4) Fastener test — recheck all bolts for proper torque. (5) Road test — drive 10 miles and recheck for clearance, loose fasteners, and air leaks. Inflate springs to 25 PSI (50 PSI if loaded) for the road test.
Inflate the air spring to 30 PSI and spray all connections and the inflation valves with a solution of 1/5 liquid dish soap and 4/5 water. Spot leaks easily by looking for bubbles in the soapy water. After the test, deflate the springs to the minimum pressure required to restore the custom ride height, no less than 10 PSI.
A 2-4 PSI loss after initial installation is normal. Check the air pressure again after 24 hours. If the loss is more than 5 PSI, retest for leaks.
After 30 days or 500 miles (whichever comes first), recheck the air spring system. If any part shows signs of rubbing or abrasion, identify the source and move it if possible. If relocation is not possible, the air spring may need to be remounted. Check all fasteners for tightness. If professionally installed, consult the installer.
Recheck air pressure after the vehicle has been used for 24 hours. If the pressure has dropped more than 5 PSI, there is a leak that must be fixed. Either fix the leak yourself or return to the installer for service.
Check the air pressure weekly to maintain optimal performance and ride height.
If the air springs are properly installed and maintained, they can last indefinitely.
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 more effort. You do not need to purchase an on-board compressor system.
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. Always add air to the springs in small quantities, checking the pressure frequently, as sleeves require less air volume than a tire and inflate quickly.
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 1/5 liquid dish soap and 4/5 water and look for bubbles to identify leaks.
If there is a problem with the swivel fitting: (1) Check the air line connection by deflating the spring and removing the line by pulling the collar against the fitting and pulling firmly on the air line. Trim 1" off the end of the air line, ensuring the cut is clean and square. Reinsert the air line into the push-to-connect fitting. (2) Check the threaded connection by tightening the swivel fitting another 1/2 turn. If it still leaks, deflate the air spring, remove the fitting, and re-coat the threads with thread sealant. Reinstall by hand tightening as much as possible, then use a wrench for an additional two turns.
If there is a problem with the inflation valve: (1) Check the valve core by tightening it with a valve core tool. (2) Check the air line connection by removing the air line from the barbed type fitting. Do not cut the air line completely off, as this will nick the barb and render the fitting useless.
Use the slotted adjustment in the lower bracket to correctly align the air spring between the upper and lower brackets. This can be accomplished by tapping it inboard (towards the vehicle) or outboard (towards the wheel) for proper alignment. There should be a symmetrical cushion of air around the base of the air spring when correctly positioned. Once aligned, tighten the lower mounting bolt securely to a maximum of 15 ft/lbs.
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. You may need to maintain different pressures on each side of the vehicle if loads such as water, fuel, and appliances cause the vehicle to be heavier on one side. As much as a 50 PSI difference between sides is not uncommon.
If the vehicle has a rough and harsh ride, it may be due to either too much pressure or not enough. Try different pressures to determine the best ride comfort. Start with the vehicle level or slightly above, and adjust the pressure up and down to find the best ride.
If the vehicle rocks and rolls, adjust the air pressure to reduce movement. Stability issues include roll control, bounce, dive during braking, and sponginess. Tuning out these problems usually requires an increase in pressure.
If the front of the vehicle dives while braking, increase the pressure in the front air bags if equipped.
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 the piston reaches the bottom of the sleeve.
The SlamAir kit (59210) is designed for lowered Ford F-150 trucks with shackle drop or flipped axle installations. Fitment depends on your specific lowering kit and optional equipment. Contact Air Lift at (800) 248-0892 to confirm compatibility.
The brake line and exhaust hanger on the inside of the frame behind the axle may need to be relocated permanently because of the mounting hardware. You will need to unbolt and move the brake line bracket on the driver side and possibly the exhaust hanger on the passenger side for drilling clearance.
Lower bracket U-bolt: 16 ft/lbs. Upper nylon nut on air spring: 4 ft/lbs. Lower mounting bolt: 15 ft/lbs maximum. Swivel air fitting: hand-tighten, then 1.5 turns with 7/16" wrench. Leaf spring U-bolts: stock specifications.
Minimum: 10 PSI (required at all times to maintain air spring shape). Maximum: 100 PSI (never exceed). Actual pressure needed depends on your load and vehicle GVWR. Failure to maintain minimum pressure voids the warranty.
Perform clearance test at 60 PSI (1/2" minimum from tire, brake drum, frame, shocks, cables), leak test at 30 PSI, heat test (6" clearance from exhaust), fastener test (recheck torque), and 10-mile road test at 25 PSI (50 PSI if loaded).
Check air pressure weekly. Maintain normal ride height. Never exceed 100 PSI. Adjust pressure when loading to maintain ride height. Add air in small quantities. If raising by frame, maintain minimum 10 PSI. Recheck system at 30 days or 500 miles for rubbing or loose fasteners.
First, check the air line connection: deflate the spring, remove the line by pulling the collar and pulling firmly, trim 1" off the end with a clean square cut, and reinsert into the fitting. If still leaking, 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, hand-tighten, then use a wrench for two additional turns.
Check the valve core by tightening it with a valve core tool. If that does not work, check the air line connection by removing the air line from the barbed fitting. Do not cut the air line completely off, as this will nick the barb and render the fitting useless.
There is a leak that must be fixed. Leak test the air line connections, threaded connection of the elbow into the air spring, and the inflation valves using a soapy water solution. Check for dirt debris in the valve core. Inspect air lines for pinches (tie straps may be too tight), holes, cracks, kinks, or folds. If these steps do not solve the problem, the air spring may have failed. Call Air Lift at (800) 248-0892 for assistance or a replacement.
Use the slotted adjustment in the lower bracket to correctly align the air spring between the upper and lower brackets by tapping it inboard (towards the vehicle) or outboard (towards the wheel). There should be a symmetrical cushion of air around the base of the air spring when correctly positioned. Once aligned, tighten the lower mounting bolt securely to a maximum of 15 ft/lbs. If rubbing persists after 30 days or 500 miles, the air spring may need to be remounted.
