If your truck has fifth-wheel hitch brackets along the side of the frame, the U-bolts cannot be used. Instead, the upper brackets are attached by drilling two 5/16" holes through the bottom of the frame and using self-tapping screws (part K), torqued to 15 lb.-ft. (20 Nm). The installation diagram notes that optional hardware (part K) is for vehicles with fifth-wheel hitches that have frame side plates.
Required tools include: metric and standard open-end box wrenches; ratchet with metric and standard sockets; drill with 5/16" bit; torque wrench; 13 mm ratcheting wrench; metric and standard hex key wrenches; hose cutter, razor blade, or sharp knife; hoist or floor jack; two safety stands; safety glasses; air compressor or compressed air source; and spray bottle with dish soap/water solution.
The kit includes: 2 air springs (58120), 2 × 90-degree swivel fittings (21837), 4 roll plates (11897), upper brackets right and left (07905, 07804), 8 × 3/8"-24 × 3/4" flat-head screws (17215), 2 lower brackets (03702), 4 U-bolts (11046), 12 × 3/8"-16 nylon lock nuts (18435), 12 × 3/8" flat washers (18444), 4 × 3/8" self-tapping screws (17129), 4 × 3/8"-16 × 3½" carriage bolts (17142), 2 clamp bars (01851), 5 M8 flat washers (18501), 3 M8-1.25 × 10 hex cap screws (17449), 1 × 3/8"-16 serrated flange lock nut (18422), 1 emergency brake cable bracket (26333), 6 zip ties (10466), 2 valve caps (21230), 4 × 5/16" hex nuts (21233), 2 × 5/16" rubber washers (21234), 2 star washers (18411), 1 air line assembly (20086), and 1 spacer (13955).
The manual does not mention disconnecting the battery. However, you must raise and support the frame with safety stands and lower the axle as far as possible before beginning installation.
Raise and support the frame with safety stands, then lower the axle as far as possible. Next, remove the jounce bumpers from both sides by prying them out with a pry bar or large screwdriver. Then remove the bolt holding the emergency brake bracket to the inside of the driver's (left) side frame rail, and remove the three bolts holding the brake lines and emergency brake cable to the rear axle jounce bumper strike plates.
1. Set a roll plate (C) on both ends of each air spring with the radiused (round) edge toward the spring. 2. Install the 90-degree elbow fitting (B) on top of the air spring and tighten finger-tight plus 1½ turns, tightening only on the metal hex nut—do not overtighten. 3. Install the upper bracket (D or E) onto the top of the air spring using 3/8" flat-head screws (F) and tighten securely. 4. Attach the lower bracket using the first and third holes on each bracket with two 3/8" flat-head screws (F), torqued to no more than 20 lb.-ft. (27 Nm), with the angled side of the lower bracket on the fitting side.
With the suspension hanging, set the left and right hand assemblies over the axle jounce bumper strike plates with the fittings on the inside of the frame. Position the upper brackets to nest around the jounce bumper mount attached to the bottom of the frame.
For trucks without a fifth-wheel hitch bracket: On late-model vehicles with a heat shield above and forward of the axle on the passenger's (right) side, remove the bolt holding the heat shield, set spacer (X) between the frame and heat shield, and reattach the heat shield with the stock bolt. Insert two U-bolts (H) onto the top of the frame through the upper bracket mounting holes, positioning them between the frame and brake lines/wiring. Cap with four 3/8" nylon lock nuts (I) and flat washers (J), torqued evenly in a criss-cross pattern to 10 lb.-ft. (14 Nm). For trucks with fifth-wheel hitch brackets: Drill two 5/16" holes through the bottom of the frame using the holes in the middle of the bracket as a template, and attach using self-tapping screws (K) torqued to 15 lb.-ft. (20 Nm).
Torque the U-bolts evenly in a criss-cross pattern to 10 lb.-ft. (14 Nm).
Attach the emergency brake cable removed during the Getting Started section using the emergency brake cable bracket (Q) and 3/8" serrated flange lock nut (P). Use the inside forward leg of the U-bolt on the driver's (left) side for the attachment and tighten securely. You may need to pinch the clamp together with pliers to align the holes enough to fit over the U-bolts.
1. Position the lower bracket to best align the air spring. 2. Insert two 3/8"-16 × 3½" carriage bolts (L) through the lower bracket mounting legs. 3. Insert the lower clamp bar (M) over the two carriage bolts and cap with two 3/8" nylon lock nuts (I) and flat washers (J), torqued evenly to 16 lb.-ft. (22 Nm). 4. Attach the brake lines and emergency brake cable that were removed earlier using the new M8 hex cap screws (O) and flat washers (N), tightened securely. 5. Attach the brake cable on the passenger's (right) side forward of the axle with a new M8-1.25 × 10 hex cap screw (O) and 3/8" flat washer (J), tightened securely. You may need to slightly bend this bracket to clear the edge of the lower bracket.
Torque the two 3/8"-16 × 3½" carriage bolts (L) with the lower clamp bar (M) evenly to 16 lb.-ft. (22 Nm).
Drilling is required only if your truck has fifth-wheel hitch brackets along the side of the frame. In that case, you must drill two 5/16" holes through the bottom of the frame using the holes in the middle of the upper bracket as a template. If your truck does not have fifth-wheel hitch brackets, no drilling is required for the upper brackets. However, you may need to drill a 5/16" (8 mm) hole for the Schrader valve location when installing the air lines.
On the passenger's (right) side of some models, it may be necessary to bend the heat shield slightly to gain access for the U-bolt to go over the frame correctly. On late-model vehicles with a heat shield above and forward of the axle, you must remove the bolt holding the heat shield, install a spacer (X) between the frame and heat shield, and reattach the heat shield with the stock bolt.
Choose the location for the Schrader valves (inside fuel tank filler door, inside rear wheel wells, or license plate/rear bumper area). Drill a 5/16" (8 mm) hole if necessary. Install the Schrader valve in the chosen location using the provided hardware: hex nut, flat washer, star washer, and rubber washer.
1. Cut the air line in half using a razor blade or hose cutter, making clean, square cuts. Do not use scissors or wire cutters. 2. Use zip ties to secure the air line to fixed points along the chassis without pinching or kinking it. Leave at least 2" (51 mm) of slack in the air line to allow for movement. The minimum bend radius for the air line is 1" (25 mm). 3. Keep at least 6" (152 mm) of clearance between all air lines and the exhaust system. Avoid sharp bends and edges.
Attach the metal heat shield to the exhaust where it is closest to the passenger's (right) side air spring. Slide the air line thermal sleeve over the air line and position it where the air line is closest to the exhaust. Maintain at least 6" (152 mm) of clearance between all air lines and heat sources.
The maximum inflation pressure is 100 PSI (7 BAR). However, the actual air pressure needed depends on load and gross vehicle weight rating. Never exceed 100 PSI or your vehicle's maximum GVWR or payload rating as indicated by the vehicle manufacturer.
The minimum recommended pressure is 5 PSI (0.34 BAR).
No. For safety and to prevent possible damage to the vehicle, do not exceed the maximum gross vehicle weight rating (GVWR) or payload rating as indicated by the vehicle manufacturer. The air springs provide load-leveling support but do not increase the vehicle's weight capacity.
1. Clearance test: Inflate to 40–60 PSI and verify at least ½" (13 mm) clearance from anything that might rub, including tires, brakes, frame, shock absorbers, and brake cables. 2. Leak test: Inflate to 40–60 PSI and check all connections for leaks using soapy water; all leaks must be eliminated before road testing. 3. Heat test: Verify at least 6" (152 mm) clearance from heat sources; install the heat shield if included. 4. Fastener test: Recheck all bolts for proper torque. 5. Road test: Drive 10 miles (16 km) and recheck for clearance, loose fasteners, and air leaks.
Check air pressure weekly. Always maintain normal ride height and never inflate beyond 100 PSI (7 BAR).
Use a soapy water solution to check all air line connections and the inflation valve core. If a leak is found, it must be repaired before the vehicle is used. If you cannot locate or repair the leak, contact Air Lift customer service at (800) 248-0892 or (517) 322-2144.
Inflate the air springs to 40–60 PSI (2.8–4.1 BAR) and use a spray bottle with dish soap/water solution to check all air line connections and the inflation valve core for bubbles, which indicate leaks. All leaks must be eliminated before the vehicle is road tested.
Yes, but the installation method differs. Instead of U-bolts, you drill two 5/16" holes through the frame and use self-tapping screws (part K) torqued to 15 lb.-ft. (20 Nm) to attach the upper brackets.
A torque wrench is essential. You also need a drill with 5/16" bit, metric and standard wrenches and sockets, hex key wrenches, hose cutter or razor blade, hoist or floor jack, safety stands, and an air compressor.
Torque the U-bolts evenly in a criss-cross pattern to 10 lb.-ft. (14 Nm).
Torque the carriage bolts (L) with the lower clamp bar (M) evenly to 16 lb.-ft. (22 Nm).
Only if your truck has fifth-wheel hitch brackets along the frame. In that case, drill two 5/16" holes through the bottom of the frame using the bracket holes as a template. Otherwise, no drilling is required for the upper brackets.
Keep at least 6" (152 mm) of clearance between all air lines and the exhaust system. Use the included heat shield and thermal sleeve where the air line is closest to the exhaust.
Never exceed 100 PSI (7 BAR). The actual pressure needed depends on your load and vehicle GVWR. Do not exceed your vehicle's maximum GVWR or payload rating.
Inflate to 40–60 PSI and check for leaks using soapy water, verify ½" clearance from tires and brakes, confirm 6" clearance from exhaust, recheck all fastener torque, then drive 10 miles and recheck everything.
Check air pressure weekly. Maintain normal ride height and never exceed 100 PSI.
