Yes, the Air Lift SlamAir for lowered trucks. 59202 (Part #BBCG59202) is designed to fit the 1988-2000 Chevrolet C2500.
The Air Lift SlamAir for lowered trucks. 59202 (Part #BBCG59202) fits 1988-2000 Chevrolet C2500 models. The 2000 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. 59202 (Part #BBCG59202) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The SlamAir kit is designed for vehicles with a Bell Tech notched frame section and rear leaf spring suspension. It bolts onto the Bell Tech C-section reinforcement brace through existing holes behind the axle. Check that your vehicle has this specific frame type and reinforcement brace before purchasing. If you are unsure whether your vehicle has the required Bell Tech C-section, contact Air Lift technical support at (800) 248-0892.
Vehicles equipped with a rear brake proportioning valve may have brake performance affected by load assist suspension products. Air Lift recommends checking with your vehicle dealer before installing this kit. If your vehicle does not have a proportioning valve or is equipped with an anti-lock brake system, no adjustment or modification is required.
No. Adding air springs will not change the weight ratings (GAWR, GCWR or GVWR) of your vehicle. You must not exceed your vehicle manufacturer's maximum gross vehicle weight rating. Exceeding the GVWR is dangerous and voids the Air Lift warranty.
The manual does not specify all required tools. You will need a jack or hoist to raise the rear of the vehicle, a wrench or socket set to remove and install bolts and nuts, a standard tube cutter, razor blade or very sharp knife to cut the air line, and a drill with a 5/16 inch bit to create the inflation valve hole. A soapy water solution is needed to test for leaks. Consult the manual or contact Air Lift at (800) 248-0892 for a complete tool list.
The kit includes: 3/8 inch lock washers and 3/8-16x7/8 inch hex head bolts for upper bracket attachment; 3/8 inch flat washers, 3/8 inch lock washers and 3/8-16x2 inch hex head bolts for lower pedestal attachment; 1/2 inch x 1.5 inch carriage bolts, flat washers, lock washers and 1/2 inch nuts for upper bracket to frame rail attachment; 3/8 inch flat washers and 3/8 inch lock nuts for U-bolt clamp bar attachment; plastic straps for air line routing; and inflation valves. The manual does not confirm whether all fasteners are included or if some must be sourced separately.
The manual does not mention disconnecting the battery. This is a mechanical suspension kit with no electrical components, so battery disconnection is not required.
The manual does not specify whether professional installation is required. The installation involves removing wheels, unbolting and rebolting suspension components, drilling a hole for the inflation valve, and cutting and connecting air lines. If you are not comfortable with these tasks, professional installation is recommended. Contact Air Lift at (800) 248-0892 for installer referrals.
1. Jack up rear of vehicle and remove rear wheels. 2. Remove four rear mounting bolts, nuts and washers from the frame rail through the Bell Tech C-section reinforcement brace. 3. Install the straight fitting into the air port on the air spring finger tight plus two turns, place the retaining collar on top, insert carriage bolts into lower holes of upper bracket, and attach air spring to upper bracket with 3/8 inch lock washer and 3/8-16x7/8 inch hex head bolts, tightened to 15 ft. lbs. 4. Position lower bracket with slots offset outboard towards the tire. 5. Attach lower pedestal to air spring with 3/8 inch flat washer, 3/8 inch lock washer and 3/8-16x2 inch hex head bolt, left loose for later adjustment. 6. Set unit on leaf spring, insert carriage bolts through frame rail holes, push lower bracket forward until it contacts axle or spring retainer bracket, mark location, remove assembly and tighten lower mounting bolts to 15 ft. lbs. 7. Set assembly back on leaf spring, attach upper bracket to frame rail using 1/2 inch x 1.5 inch carriage bolts, flat washers, lock washers and 1/2 inch nuts, tightened to 50 ft. lbs. 8. Attach lower bracket by inserting U-bolt over front of lower bracket, slide clamp bar onto U-bolt with short leg forward, lock short leg under edge of spring retainer bracket, install 3/8 inch flat washer and 3/8 inch lock nuts, tightened to 20 ft. lbs. 9. Repeat steps 2-8 for passenger side. 10-13. Install inflation valves and air lines.
The lower bracket is marked left for driver side and right for passenger side. The slots in the lower bracket must be offset outboard towards the tire. Position the hook of the lower bracket in relationship to the upper bracket as shown in Figure 2 of the manual. The lower bracket is slotted for front-to-back adjustment; push it forward until it contacts the axle or spring retainer bracket.
The 3/8-16x2 inch hex head bolt that attaches the lower pedestal to the air spring should be left loose for later adjustment (Step 5). After you position the lower bracket forward until it contacts the axle or spring retainer bracket and mark the location (Step 6), you then tighten the lower mounting bolts to 15 ft. lbs. The lower pedestal bolt is tightened as part of the U-bolt clamp bar assembly in Step 8.
Yes. You must drill a 5/16 inch hole in the rear bumper area or rocker panel flange to mount the inflation valve. The manual specifies that the hole should be drilled where the valve will be protected and accessible with an air hose. No other drilling is required; the kit bolts into existing holes in the Bell Tech C-section reinforcement brace.
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. The air line will insert 5/8 inch into the fitting.
Upper bracket to air spring: 3/8-16x7/8 inch hex head bolts, tightened to 15 ft. lbs. Lower mounting bolts (frame rail): 15 ft. lbs. Upper bracket to frame rail: 1/2 inch x 1.5 inch carriage bolts with 1/2 inch nuts, tightened to 50 ft. lbs. Lower bracket U-bolt clamp bar: 3/8 inch lock nuts, tightened to 20 ft. lbs.
1. Select a location for the inflation valve in the rear bumper area or rocker panel flange where it will be protected and accessible. 2. Drill a 5/16 inch hole. 3. Cut the air line in two equal lengths with a clean square cut using a tube cutter, razor blade or sharp knife. 4. Route the air line along the frame to the inflation valve location, attaching it to the chassis with provided plastic straps. Keep the air line at least 12 inches from the exhaust system to prevent melting. 5. Leave sufficient air line slack to prevent strain on the valve stem during normal axle motions. 6. Cut off excess air line squarely and install it into the fitting by pushing and slightly turning the cut end as far as it will go. You will hear or feel a definite click when the air line is seated. The air line will go in 5/8 inch. 7. Repeat for the right side.
The air line must be kept at least 12 inches from the exhaust system to prevent the air line from melting. Route the air line along the frame and attach it to the chassis with the provided plastic straps.
The minimum air pressure is 5 p.s.i. You must maintain at least 5 p.s.i. at all times to prevent chafing and keep the air spring in shape. Failure to maintain minimum air pressure will void the warranty. A 2-4 p.s.i. loss after initial installation is normal.
The maximum air pressure is 100 p.s.i. However, this pressure may represent too great a load on some vehicles. Check your vehicle owner's manual and do not exceed the maximum loads listed for your vehicle. Do not exceed your vehicle manufacturer's maximum gross vehicle weight rating.
No. The air spring must not be the suspension limiter in either extension or compression. Most vehicles have a hard rubber compression stop on the rear suspension, and the shock absorber is usually the limiter in full extension. If the air spring becomes the suspension limiter, it will be damaged and the warranty will be voided.
1. Inflate the air springs to 30 p.s.i. 2. Check all fittings and valve core with a soapy water solution for leaks. 3. Check that there is proper clearance all around the air spring when inflated; there must be sufficient clearance on all sides. 4. 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., re-test for leaks with a soapy water solution.
Check the air pressure weekly. Always maintain at least 5 p.s.i. to prevent chafing and keep the air spring in shape.
If the air springs are properly installed and maintained, they can last indefinitely. Proper maintenance includes checking pressure weekly, maintaining at least 5 p.s.i. at all times, and checking for leaks if pressure drops.
Use a soapy water solution to check all air line connections and the inflation valve core before removing the air spring. This will help you identify where the leak is located so you can address it without unnecessary disassembly.
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. 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 suspension and brake components.
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 more effort. When inflating, add pressure in small quantities and check frequently, as the air spring sleeves require much less air volume than a tire and inflate much quicker.
1. Inflate your air springs to 60 p.s.i. before adding the payload. 2. After the vehicle is loaded, adjust air pressure to level the vehicle and for ride comfort. 3. When carrying a payload, increase tire inflation pressure in proportion to the 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. 4. Do not exceed the maximum load recommended by your vehicle manufacturer.
The kit is designed for vehicles with a Bell Tech notched frame and rear leaf springs. It bolts onto the Bell Tech C-section reinforcement brace through existing holes behind the axle. Verify your vehicle has this specific frame type before purchasing.
Upper bracket to air spring: 15 ft. lbs. Lower mounting bolts: 15 ft. lbs. Upper bracket to frame rail: 50 ft. lbs. Lower bracket U-bolt clamp bar: 20 ft. lbs.
The air line must be kept at least 12 inches from the exhaust system to prevent melting. Route it along the frame and secure with provided plastic straps.
Inflate to 30 p.s.i. and check all fittings and valve core with soapy water for leaks. Verify clearance around the inflated air spring. Recheck pressure after 24 hours; a 2-4 p.s.i. loss is normal.
Check weekly and maintain at least 5 p.s.i. at all times. If pressure drops more than 5 p.s.i. after initial installation, test for leaks with soapy water.
Yes, for short-term service work. For prolonged hoist time, support the axle with jack stands. If raising by frame, reduce system pressure to 5 p.s.i.
A 2-4 p.s.i. loss after initial installation 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. Apply the soapy water to each connection and look for bubbles indicating the leak location.
Ensure the air line is cut squarely with a clean edge using a tube cutter, razor blade or very sharp knife. Push and slightly turn the cut end of the air line into the fitting as far as it will go. You will hear or feel a definite click when the air line is properly seated. The air line should go in 5/8 inch. If it does not click or seat, the cut may not be square; trim the end and try again.
If the vehicle's headlights are shining into the trees or the vehicle is leaning to one side, raise the air pressure to correct the problem and level the vehicle. Start with the vehicle level or slightly above level, and add air pressure as needed. It may be necessary to maintain different pressures on each side of the vehicle if loads such as water, fuel or appliances cause uneven weight distribution.
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. However, stability should be the priority over a perfectly level and comfortable ride. If the vehicle has stability issues such as roll control, bounce, dive during braking or sponginess, increase the pressure to address these problems.
Stability issues including bounce, sway and body roll usually require an increase in air pressure. Adjust the air pressure up to reduce movement and improve stability. If the vehicle rocks and rolls, adjust the air pressure to reduce this movement. Stability translates into safety and should be the priority.
If the front of the vehicle dives while braking, increase the pressure in the front air bags if equipped. However, this kit is for rear suspension only. If you have front air bags from another Air Lift product, adjust their pressure to reduce brake dive.
If it is suspected that the air springs have bottomed out, increase the air pressure. Bottoming out occurs when the air spring compresses fully and the internal components contact each other. Increasing pressure will prevent this condition. Failure to maintain minimum pressure or allowing bottoming out will void the warranty.
