Yes, the LoadLifter 5000 Series kits (part numbers 57331 and 88331) are designed for the Nissan Titan. The manual does not specify model years or any exclusions based on cab style, bed length, or drivetrain, so contact Air Lift customer service at (800) 248-0892 or service@airliftcompany.com if you need to confirm fitment for your specific vehicle.
The two kits differ in the air spring component and roll plate finish. Kit 57331 uses air spring part number 58494 with zinc-plated steel roll plates (standard LoadLifter 5000). Kit 88331 uses air spring part number 58439 with black powder-coated roll plates (LoadLifter 5000 Ultimate). All other hardware is the same. You can identify which kit you have by examining the roll plates: silver zinc-plated indicates kit 57331, and black powder-coated indicates kit 88331.
Required tools include: standard and metric open-end or boxed wrenches (set), standard and metric regular and deep-well sockets (set), ratchet, torque wrench, 7/32 inch hex-key wrench (socket preferable), large screwdriver or equivalent, hose cutter, razor blade, or sharp knife, hoist or floor jack, 2 safety stands, safety glasses, air compressor or compressed air source, and spray bottle with dish soap/water solution.
Common parts in all kits include 4 roll plates (part 11967 or 11951 depending on kit) and 2 air springs (part 58494 for kit 57331 or 58439 for kit 88331). Additional hardware includes 2 lower brackets, 1 right-hand upper bracket, 1 left-hand upper bracket, 2 swivel elbow fittings, 4 flat-head screws, 4 hex flange bolts, 4 U-bolts for leaf springs, 4 frame U-bolts, 2 M8 hex flange bolts, 16 serrated flange nuts, 1 air line assembly, 6 zip ties, 2 lock washers, 2 rubber washers, 2 M8 flat washers, 4 hex nuts, 2 valve caps, and 2 self-tapping screws. See the Hardware and Tools Lists table on page 3 for part numbers.
The manual does not mention disconnecting the battery. However, the installation does involve working near the wiring harness and brake lines, so consult your vehicle's service manual or contact Air Lift customer service at (800) 248-0892 if you have concerns about electrical safety.
Yes. Step 1 of Preparing the Vehicle states: 'Remove the rear wheels.' The wheels must be removed to access the jounce bumper, mounting cup, and leaf springs where the air spring assemblies are installed.
Yes. Step 2 of Preparing the Vehicle requires you to remove the jounce bumper (if equipped) from the mounting cup and unbolt the mounting cup from the jounce bumper mounting bracket welded to the frame. The manual states to discard both the jounce bumper and mounting cup.
Drilling is required only for the Schrader valve installation. You must drill a 5/16 inch (8 mm) hole if necessary at the chosen location for the Schrader valve (inside the fuel tank filler door, inside rear wheel wells, or license plate/rear bumper area). No drilling is required for the main air spring assembly installation.
Yes. Step 2 of Installing the Air Lines requires you to cut the air line in half. Make clean, square cuts using a razor blade or hose cutter. Do not use scissors or wire cutters. After cutting, insert the air line into the fitting on the air spring assembly.
The installation sequence is: 1) Prepare the vehicle (lift, support with safety stands, remove wheels, remove jounce bumper and mounting cup, pry brake line holders for clearance). 2) Install upper brackets (set frame U-bolts, install upper brackets with M8 bolts and serrated flange nuts, adjust wiring harness if needed). 3) Assemble air springs (place roll plates on air springs, install swivel elbow fittings, flip and install lower brackets, flip again and loosely install hex flange bolts). 4) Install air spring assemblies (drop axle, set assemblies on leaf spring, raise axle to seat against upper bracket, install leaf spring U-bolts, torque lower and upper mounting hardware). 5) Install air lines (drill Schrader valve hole, cut air line, route and secure with P-clamp and zip ties, install Schrader valve). 6) Finish (raise axle, remove safety stands, install wheels, torque lug nuts).
1) Set the frame U-bolts (part K) over the frame, forward and rearward of the axle, on both driver's (left) and passenger's (right) sides. 2) Using a long socket, insert the M8 hex flange bolt (part M) through the passenger's (right) side upper bracket (part B). Position the upper bracket under the jounce bumper bracket while inserting the U-bolts through the mounting holes. 3) Install the M8 bolt into the jounce bumper mounting hole and tighten finger tight. Tighten the U-bolts finger tight using 3/8 inch-16 serrated flange nuts (part N). 4) Torque the M8 hex flange bolt first to 15 lb.-ft. (11 Nm), then tighten the 3/8 inch-16 serrated flange nuts evenly to 15 lb.-ft. (11 Nm). 5) Repeat for the driver's (left) side. Caution: Do not pinch any brake or stock wiring harness components between the U-bolt and frame.
1) Place the roll plates (part D) on the air springs (part E). Install the swivel elbow air fittings (part F) onto the air springs and tighten finger tight plus 1½ turns. 2) Flip both air springs over so the fitting is down. Install the lower brackets (part A) so that the 'window' on the bracket is on the same side as the fitting. Attach with 3/8 inch-24 x 3/4 inch flat-head screws (part G) and torque to no more than 20 lb.-ft. (27 Nm). Use caution when flipping to avoid damaging the fittings. 3) Flip both assemblies so the lower bracket is down. Loosely install the 3/8 inch-24 x 5/8 inch hex flange bolts (part H) in the top mounting holes. These bolts must stay loose for installation. Point the fittings inward toward the center of the air spring.
1) Drop the axle down low enough to place the assemblies onto the leaf spring. Set the assemblies into position, ensuring the fitting is on the tire (not frame) side of the vehicle and pointing inward toward the center. 2) Raise the axle until the hex flange bolts and fittings index into the large opening of the 'keyhole' mounting holes in the upper brackets. Raise the axle far enough to seat the upper spring assembly against the upper bracket. 3) Push the lower bracket/air spring assembly inward far enough to install the leaf spring U-bolts (part J) through the holes in the lower bracket. Install the U-bolts and loosely thread the 3/8 inch serrated flange nuts (part N) over them. Raise the axle all the way up and adjust the lower bracket forward or backward to align the air spring. Evenly torque the lower mounting hardware to 15 lb.-ft. (11 Nm). 4) Adjust the upper mounting bracket in and out to align the air spring and evenly tighten the upper flange bolts with a 9/16 inch boxed-end wrench until secure. Do not overtighten. 5) Rotate the fittings so they face outward for hose installation and routing.
1) Choose locations for the Schrader valves (inside fuel tank filler door, inside rear wheel wells, or license plate/rear bumper area) and drill a 5/16 inch (8 mm) hole if necessary. 2) Cut the air line in half using a razor blade or hose cutter, making clean, square cuts. Do not use scissors or wire cutters. 3) Route the air line along the top of the frame, in front or behind the axle, then down to the fitting. After cutting to length, insert the air line into the fitting. 4) Secure the air line to the upper jounce bumper mounting bracket by attaching a P-clamp (part I) around the hose and driving a #14-1/4 inch x 3/4 inch self-tapping screw (part L) using the small hole as a pilot. 5) Use zip ties (part BB) to secure the air line to fixed points along the chassis. Do not pinch or kink the air line. The minimum bend radius is 1 inch (25 mm). Leave at least 2 inches (50 mm) of slack to allow for movement. 6) Install the Schrader valve in the chosen location. Keep at least 6 inches (150 mm) clearance between all air lines and the exhaust system.
Torque specifications are: M8 hex flange bolt (part M) at upper bracket: 15 lb.-ft. (11 Nm). 3/8 inch-16 serrated flange nuts (part N) at upper bracket: 15 lb.-ft. (11 Nm). 3/8 inch-24 x 3/4 inch flat-head screws (part G) at lower bracket: no more than 20 lb.-ft. (27 Nm). Lower mounting hardware (leaf spring U-bolts and serrated flange nuts): 15 lb.-ft. (11 Nm). Upper flange bolts (part H): tighten until secure, do not overtighten. Wheel lug nuts: 100 lb.-ft. (135 Nm) in a criss-cross pattern.
On some models, it may be necessary to move the wiring harness inside the passenger's (right) side frame, forward of the axle, away from the corner of the upper bracket. Pull the Christmas tree hanger away from the frame and bracket, then zip tie the harness to the crossmember above the axle. The manual notes that Fig. 10 shows an acceptable installation with no further modification needed unless interference is more direct. Contact Air Lift customer service at (800) 248-0892 if you encounter direct interference.
The maximum air pressure is 100 PSI (7 BAR). Never inflate beyond this pressure. Although the air springs are rated at a maximum inflation pressure of 100 PSI (7 BAR), the air pressure actually needed is dependent on load and gross vehicle weight rating. Always maintain normal ride height and do not exceed the vehicle's maximum gross vehicle weight rating (GVWR) or payload rating as indicated by the vehicle manufacturer.
The minimum recommended pressure is 5 PSI (0.34 BAR). The system is adjustable from 5–100 PSI (0.34–7 BAR).
After installation, inflate the air springs to 40–60 PSI (2.8–4.1 BAR) and ensure there is at least 1/2 inch (13 mm) clearance from anything that might rub against each sleeve. Be sure to check the tire, brakes, frame, shock absorbers, and brake cables. Additionally, keep at least 6 inches (150 mm) of clearance between all air lines and the exhaust system, and at least 6 inches (152 mm) clearance from heat sources for air springs and air lines.
The minimum bend radius for the air line is 1 inch (25 mm). Avoid sharp bends and edges. Leave at least 2 inches (50 mm) of slack in the air line to allow for any movement that might pull on the air line.
The Installation Checklist requires: 1) Clearance test — Inflate to 40–60 PSI (2.8–4.1 BAR) and verify at least 1/2 inch (13 mm) clearance from tire, brakes, frame, shock absorbers, and brake cables. 2) Leak test — Inflate to 40–60 PSI (2.8–4.1 BAR) and check all connections for leaks before road testing. 3) Heat test — Verify at least 6 inches (152 mm) clearance from heat sources. 4) Fastener test — After 500 miles, 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. 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. Do not exceed the vehicle's maximum gross vehicle weight rating (GVWR) or payload rating.
Use a soapy water solution to check all air line connections and the inflation valve core. Spray the solution on all connections and look for bubbles, which indicate a leak. The manual recommends performing a leak test after installation by inflating the air springs to 40–60 PSI (2.8–4.1 BAR) and checking all connections for leaks before road testing. All leaks must be eliminated before the vehicle is road tested.
After installation, maintain at least 1/2 inch (13 mm) clearance from the tire, brakes, frame, shock absorbers, and brake cables. Keep at least 6 inches (150 mm) clearance between air lines and the exhaust system.
Perform a clearance test (1/2 inch minimum), leak test (inflate to 40–60 PSI), heat test (6 inches minimum from heat sources), and after 500 miles, recheck all bolts for proper torque. Road test for 10 miles and recheck clearance, fasteners, and leaks.
Check air pressure weekly. After 500 miles, recheck all bolts for proper torque.
Use a soapy water solution to check all air line connections and the inflation valve core. Spray the solution on all connections and look for bubbles, which indicate a leak. Inflate the air springs to 40–60 PSI (2.8–4.1 BAR) before testing. All leaks must be eliminated before the vehicle is road tested. If a leak is found, deflate and remove the air spring to repair or replace the affected component.
After installation, inflate the air springs to 40–60 PSI (2.8–4.1 BAR) and check for at least 1/2 inch (13 mm) clearance from anything that might rub against each sleeve, including the tire, brakes, frame, shock absorbers, and brake cables. If clearance is insufficient, adjust the position of the lower bracket forward or backward to align the air spring properly. If rubbing persists, contact Air Lift customer service at (800) 248-0892 for assistance.
After 500 miles of driving, recheck all bolts for proper torque. Refer to the torque specifications: M8 hex flange bolts at upper bracket: 15 lb.-ft. (11 Nm); 3/8 inch-16 serrated flange nuts at upper bracket: 15 lb.-ft. (11 Nm); lower mounting hardware: 15 lb.-ft. (11 Nm); 3/8 inch-24 x 3/4 inch flat-head screws at lower bracket: no more than 20 lb.-ft. (27 Nm); wheel lug nuts: 100 lb.-ft. (135 Nm). Retighten any loose fasteners to the specified torque value.
