The Air Lift SLAM AIR 59103 (Part #BBCG59103) fits 1988-1998 Chevrolet C1500 models. The 2009 model year is the last year covered by this part number. For newer models, check for an updated version.
Yes, the Air Lift SLAM AIR 59103 (Part #BBCG59103) is designed to fit the 1988-1998 Chevrolet C1500.
The Air Lift SLAM AIR 59103 (Part #BBCG59103) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The SlamAir air spring kit is a load support system designed for custom lowered vehicles. It uses two air springs (part 58482) mounted between the frame and axle to maintain ride height and support load. The kit is universal for custom applications and includes all necessary brackets, air lines, fittings, and hardware for installation.
The SlamAir kit is universal for custom lowered vehicles, but Air Lift cannot guarantee it will fit every vehicle due to the wide variety of lowering kits on the market. You may need to modify or weld the upper bracket depending on your lowering kit type and optional equipment. The kit includes an installation tool to help check for obstacles and determine the best installation position. Consult Air Lift customer service at (800) 248-0892 if you have fitment questions.
The kit requires a minimum of 5 inches of clearance between the frame and tire for a fully inflated air spring. Measure this distance before installation to ensure adequate space.
Yes. The 1999 Silverado/Sierra has specific instructions that differ from other vehicles. The upper rearward hole must line up on a reinforcing frame ridge (if present), and a square spacer (part 13377) is inserted between the upper bracket and frame. Drill a 3/8" hole for the rear lower hole and a 5/16" hole for the forward lower hole. If your model does not have the reinforcing ridge, follow the same installation procedure in the same position. See pages 7–8 for detailed steps.
Yes. Many Dodge and Ford pickup chassis have an indent in the frame rail. Use two round spacers (part 13225) per side for Dodge, or one square spacer (part 13377) per side for Ford, behind the mounting holes in the upper bracket that fall into the indented area.
Required tools include: 1/2", 3/4", 7/16" and 1 1/16" open-end or box wrenches; ratchet with 3/8", 9/16" and 1/2" deep well sockets; torque wrench; 3/8" nut driver; sharp 3/8" drill bit; heavy duty drill; hose cutter, razor blade or sharp knife; hoist or floor jack; safety glasses; two safety stands; air compressor or compressed air source; and spray bottle with dish soap/water solution.
The kit includes: two air springs (58482), installation tool with nylon nut (10549), two upper brackets (07940), two lower brackets (03616), two clamp bars (01426), two nylon nuts (18454), two U-bolts (10583), four 3/8" × 1" self-tapping screws (17139), six 3/8" flat washers (18444), eight 3/8" oversized flat washers (18447), eight 3/8" lock nuts (18435), two 1/2" × 7/8" hex head cap screws (17124), two 1/2" flat washers (18414), two square spacers (13377), eight washer head frame bolts (17129), four round spacers (13225), two 90-degree swivel air fittings (21837), 16 feet of air line (20086), six zip ties (10466), two valve caps (21230), two M8 flat washers (18501), two rubber washers (21234), two star washers (18411), and four 5/16" hex nuts (21233).
The 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 the custom, lowered condition. To determine it: (1) remove unusual loads and examine the vehicle from the side on a level surface; (2) if leaf springs are sagging badly, use a jack to raise the rear end until the vehicle achieves the desired custom lowered ride height. The vehicle must be at this custom ride height during installation.
Raise the vehicle and remove the wheels. Ensure the vehicle is at custom lowered ride height. If using an axle contact hoist, place axle stands under the frame and lower the axle as needed. If using a frame contact hoist, place axle stands under the axle and lower the frame as needed. If using a jack with axle stands on the frame, use a floor jack to raise the axle. The vehicle must remain at custom ride height throughout installation.
The installation tool (part 10549) helps position the upper bracket for drilling and ensures proper air spring alignment. To assemble: (1) secure the upper bracket (07940) to the installation tool using the provided nylon nut (18454); (2) loosely attach the tool to the lower bracket (03616) using a 1/2" flat washer (18414) and 1/2" hex head cap screw (17124). Leave this connection loose for later adjustment. The tool is rigid and self-aligning. The upper bracket may need to be inverted depending on your lowering kit type.
Set the installation tool assembly on the leaf spring. Place the hook end of the lower bracket over the stock U-bolt or the edge of the upper spring retaining plate—this prevents the bracket from walking up the leaf spring. Attach the lower bracket using the supplied U-bolt (10583), lower clamp bar (01426), 3/8" flat washers (18444), and nylon lock nuts (18435). Torque to 16 lb.-ft. The bracket will pull down flat to the leaf spring when the nuts are tightened.
Using the slot in the lower bracket, push the upper bracket against the frame rail. Using the supplied nylon nuts (18454), adjust the upper bracket so that the legs are flat against the frame rail and all four holes are in the middle section of the frame. The mounting holes must stay 3/4" from the rounded edges of the frame rail. At least 1 1/2" must be left above the top of the upper bracket for air fitting clearance. The brackets can be mounted anywhere within the threaded range of the installation tool. On some models, the upper bracket may need to be inverted in a "legs up" position.
For vehicles other than 1999 Silverado/Sierra: drill two 3/8" holes for the lower mounting holes and two 5/16" holes for the upper mounting holes. Use the upper bracket as a template and center punch before drilling. Before drilling, check the back side of the frame for clearance issues such as brake lines, gas lines, and electrical lines. All obstacles must be temporarily relocated to clear the drilling area.
For 1999 Silverado/Sierra: drill a 3/8" hole for the lower rear hole (which lines up on the reinforcing frame ridge), a 5/16" hole for the forward lower hole, a 5/16" hole for the forward upper hole, and a 3/8" hole for the rear upper hole. Before drilling any holes, check the back side of the frame for clearance issues such as brake lines, gas lines, and electrical lines. All obstacles must be temporarily relocated.
Yes. Drilling is required to mount the upper bracket to the frame. You must drill between two and four holes depending on your vehicle type and installation method. A sharp 3/8" drill bit and heavy duty drill are required tools. Center punch each hole location before drilling. Before drilling, check the back side of the frame for brake lines, gas lines, electrical lines, and other obstacles that must be temporarily relocated.
Torque the lower bracket U-bolt (10583) with clamp bar (01426), flat washers (18444), and nylon lock nuts (18435) to 16 lb.-ft.
Torque all upper bracket frame bolts to 20 lb.-ft. This applies to the washer head frame bolts (17129) with oversized flat washers (18447) and lock nuts (18435) on non-Silverado/Sierra vehicles. For 1999 Silverado/Sierra, tighten the rear lower hole frame bolt securely after initial installation, then torque all fasteners to 20 lb.-ft. after drilling and installing all four holes.
Tighten the lower mounting bolt (17124) to 10 lb.-ft. using a 3/4" open end wrench. This is done after aligning the air spring with approximately 10 PSI of inflation.
Tighten the upper nylon nut (18454) to 4 lb.-ft. using a 1 1/16" open end wrench. Do not overtighten. This is done after aligning the air spring with approximately 10 PSI of inflation.
Install the 90-degree swivel air fitting (21837) into the top of the air spring (58482). Tighten with fingers first, then seal the fitting by tightening 1 1/2 turns with a 7/16" open-end wrench, being careful to tighten on the metal hex nut only. Do not overtighten. The swivel air fitting is precoated with sealant.
Minimum recommended air pressure is 10 PSI (0.69 BAR). Maximum air pressure is 100 PSI (7 BAR). Never inflate beyond 100 PSI. The actual air pressure needed depends on load and gross vehicle weight rating. Always maintain normal ride height regardless of load.
The air spring can compress to 3.0" and extend to 9.1". Regardless of load, air pressure should be adjusted so that ride height is maintained at all times. The shock absorber is usually the limiter on extension. If this is not the case, consider using limiting straps.
Choose locations for the Schrader valves that provide convenient access. Recommended locations include: inside the fuel tank filler door, inside rear wheel wells, or the license plate or rear bumper area. Drill a 5/16" (8mm) hole if necessary. Install the Schrader valve using the provided hex nuts, flat washer, star washer, and rubber washer.
Cut the 16-foot air line (20086) in half using a razor blade or hose cutter, making clean, square cuts. Do not use scissors or wire cutters. Use zip ties (10466) to secure the air line to fixed points along the chassis. Do not pinch or kink the air line. Leave at least 2" (51mm) of slack in the air line to allow for movement. The minimum bend radius for the air line is 1" (25mm).
Do not try to inflate the air springs 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 air springs must be fully mounted to both the upper and lower brackets before any inflation occurs.
No. The installation of this kit does not alter the Gross Vehicle Weight Rating (GVWR) or payload of the vehicle. You must check your vehicle's owner's manual and not exceed the maximum load listed for your vehicle. Gross Vehicle Weight Rating is the maximum allowable weight of the fully loaded vehicle (including passengers and cargo) and is shown on the vehicle's Safety Compliance Certification Label. Payload is the combined maximum allowable weight of cargo and passengers, calculated as GVWR minus Base Curb Weight.
Your vehicle may be equipped with a rear brake proportioning valve. Any type of load assist product could affect brake performance. Air Lift recommends checking with your dealer before installing this type of product. If your vehicle does not have a rear brake proportioning valve or is equipped with an anti-lock type brake system, installation of the load assist product will have no effect on brake system performance.
Keep at least 6" (152mm) of clearance between all air lines and the exhaust system. Avoid sharp bends and edges. Also ensure at least 6" (152mm) clearance from heat sources for both air springs and air lines. If a heat shield was included in the kit, install it. If one is required but not included, call Air Lift customer service at (800) 248-0892.
Complete the following checks before road testing: (1) Clearance test—inflate air springs to 60 PSI and verify at least 1/2" clearance from tire, brakes, frame, shock absorbers, and brake cables; (2) Leak test—inflate to 60 PSI and check all connections for leaks; (3) Heat test—verify 6" clearance from heat sources; (4) Fastener test—after 500 miles, recheck all bolts for proper torque; (5) Road test—drive 10 miles and recheck for clearance, loose fasteners, and air leaks.
With the top and bottom of the air spring still loose, inflate to approximately 10 PSI. Use the slotted adjustment in the lower bracket to 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. Then tighten the lower mounting bolt to 10 lb.-ft. and the upper nylon nut to 4 lb.-ft.
Check air pressure weekly. Always maintain normal ride height. Never inflate beyond 100 PSI (7 BAR). After 500 miles, recheck all bolts for proper torque. If the system develops an air leak, use a soapy water solution to check all air line connections and the inflation valve core before deflating and removing the air spring.
Use a spray bottle with a dish soap and water solution to check all air line connections and the inflation valve core. Spray the solution on all connections while the air springs are inflated to 60 PSI. Bubbles will form at any leak location. All leaks must be eliminated before the vehicle is road tested.
The SlamAir kit is universal for custom lowered vehicles, but fitment varies by lowering kit type and optional equipment. You may need to modify or weld the upper bracket. The kit includes an installation tool to check for obstacles. Contact Air Lift at (800) 248-0892 for fitment confirmation.
The kit requires a minimum of 5 inches of clearance between the frame and tire for a fully inflated air spring.
You need wrenches (1/2", 3/4", 7/16", 1 1/16"), ratchet with sockets, torque wrench, 3/8" nut driver, sharp 3/8" drill bit, heavy duty drill, hose cutter, hoist or floor jack, safety glasses, two safety stands, and air compressor.
Lower bracket U-bolt: 16 lb.-ft. Upper bracket frame bolts: 20 lb.-ft. Air spring lower mounting bolt: 10 lb.-ft. Air spring upper nylon nut: 4 lb.-ft. Air fitting: 1.5 turns with 7/16" wrench (do not overtighten).
Maximum air pressure is 100 PSI (7 BAR). Never inflate beyond this limit. Minimum recommended pressure is 10 PSI (0.69 BAR). Actual pressure needed depends on load and vehicle GVWR.
Inflate to 60 PSI and check: (1) at least 1/2" clearance from tire, brakes, frame, shocks, and cables; (2) all connections for leaks using soapy water; (3) 6" clearance from heat sources. After 500 miles, recheck all bolts for proper torque.
Check air pressure weekly. Maintain normal ride height. Never exceed 100 PSI. After 500 miles, recheck all bolts for proper torque. Use soapy water to check for leaks if pressure drops.
With the air spring inflated to approximately 10 PSI and the top and bottom still loose, use the slotted adjustment in the lower bracket to tap the air spring inboard (towards the vehicle) or outboard (towards the wheel) until there is a symmetrical cushion of air around the base of the air spring. Once properly aligned, tighten the lower mounting bolt to 10 lb.-ft. and the upper nylon nut to 4 lb.-ft.
Use a spray bottle with a dish soap and water solution to check all air line connections and the inflation valve core. Spray the solution on all connections while the air springs are inflated to 60 PSI. Bubbles will form at any leak location. All leaks must be eliminated before the vehicle is road tested. If leaks persist, contact Air Lift customer service at (800) 248-0892.
Inflate the air springs to 60 PSI and check for at least 1/2" (13 mm) clearance from the tire, brakes, frame, shock absorbers, and brake cables. If clearance is insufficient, the installation may not be suitable for your vehicle. Consult Air Lift customer service at (800) 248-0892 for guidance. Do not operate the vehicle if clearance is inadequate.
