The purpose of this publication is to assist with the installation of the LoadLifter 5000 series
air spring kits. All LoadLifter 5000 series kits utilize sturdy, reinforced, commercial-grade
single or double, depending on the kit, convolute bellows.
The air springs are manufactured like a tire with layers of rubber and cords that control
growth. LoadLifter 5000 kits provide up to 5,000 pounds (2,268kg) of load-leveling support
with air adjustability from 5-100 PSI (.34-7BAR).
It is important to read and understand the entire installation guide before beginning
installation, as well as, read and understand the entire user guide before performing any
maintenance, service or repair.

GETTING STARTED
COMPRESSED AIR CAN CAUSE INJURY AND DAMAGE TO THE VEHICLE AND PARTS
IF IT IS NOT HANDLED PROPERLY. FOR YOUR SAFETY, DO NOT TRY TO INFLATE THE
AIR SPRINGS UNTIL THEY HAVE BEEN PROPERLY SECURED TO THE VEHICLE.
1. Raise the vehicle and support the axle with safety stands, setting the safety stands
as wide as possible on the axle (fig. 2).
2. Drop the axle or raise the frame up to make room for the assemblies to be put into
position between the frame and axle.
3. Remove and discard the line holder located on the left (driver’s) side of the frame rail
on the inside of the frame, just forward of the axle (fig. 3).
Late model line holders may look different than the one pictured in Figure 3.
4. Pull up on and remove the pin holding the line holder in place on top of the frame
(fig. 4). Unhook the lines and remove the line holder. Discard the line holder.

5. Pull the ABS line holders attached to the bottom of the frame, behind the axle, on
the left (driver’s) and right (passenger’s) sides, out from the frame and remove from
the ABS line (fig. 5).
6. Use a small screwdriver to unhook the clamp from the line and remove. Discard the
clamp.
7. Install the small frame clamps (J) onto the ABS line where the stock line holders
were attached with the hole facing forward on the line (fig. 6). Do this for both sides.
8. Leave the ABS line hanging loose for later installation.
BECAUSE THE EMERGENCY BRAKE CABLE IS IN A LOCATION THAT MAKES IT
POSSIBLE TO RUB A HOLE IN THE SIDE OF THE AIR SPRING FLEX MEMBER, IT WILL
BE NECESSARY TO RELOCATE IT.

15. Install the large frame clamp onto the U-bolt (L), inside the frame on the left (driver’s)
side with the clamp pointing inboard toward the center of the vehicle (fig. 10).
16. Torque the U-bolt as specified in step 9 if using the U-bolt to mount the upper
bracket (fig. 10). If the truck has a fifth-wheel bracket use the center hole, instead of
the U-bolt, to mount the upper bracket. Attach the large frame clamp (I) using the
3/8” bolt (V), 3/8” flat washer (S) and nylon lock nut (R) supplied. Tighten to 10 lb.-ft.
(14Nm).
17. Remove the jounce bumper by unbolting it from the jounce bumper mounting cup
welded to the frame. Pull or pry the jounce bumper out of the cup with a screwdriver

BUILDING THE AIR SPRING ASSEMBLIES
1. Set a roll plate (E) over the top of the air spring (D) (fig. 12).
The radiused (rounded) edge of the roll plate (E) will be toward the air spring so that the air
spring is seated inside both roll plates.
2. Install the swivel fitting (F) into the top of the air spring finger tight plus one and a
half turns. Do not overtighten.
3. Install the upper bracket (A or B) onto the air spring (D) using four flat-head screws
(G) (fig. 13). Torque to no more than 20 lb.-ft. (27Nm).
4. Install the lower bracket (C) onto the bottom of the air spring using the flat-head
screws (G) (fig. 14). Torque to no more than 20 lb.-ft. (27Nm).

3. Set the left assembly (with the L on the bracket) on the left (driver’s) side of the axle.
Repeat for the right (passenger’s) side.
The fitting on both air springs will be inboard.
4. While raising the assembly, line up the bolt previously installed with the back hole on the
bracket. Set the new ABS line holder over the bolt once the upper bracket is in place
and cap with a flat washer (S) and nylon lock nut (R) (fig. 18). Leave loose at this time.
There are two ways to attach the front side of the upper bracket depending on whether
the truck has a fifth-wheel bracket running alongside the frame or not.
For vehicles with NO fifth-wheel bracket along the side of the frame, perform the
following steps:
On late model vehicles, there is a heat shield above and forward of the axle, on the
passenger (right) hand side of the vehicle that will be in the way of the U-bolt. For models
without a heat shield, proceed to step 7.
HEAT SHIELD HAS SHARP EDGES, USE CAUTION WHEN REMOVING THE BOLT.
5. Using a ratcheting wrench, remove the bolt that holds the heat shield on the frame above
and forward of the axle. Set the bolt aside (fig. 19).
6. Set a U-bolt (L) into position around the frame (fig 20). Set spacer (KK) between the frame
and heat shield and reattach the heat shield with the stock bolt previously removed.

around the frame (Fig. 20) and insert the U-bolt (L) through the holes in the upper bracket
forward of the axle (Fig. 21).
DO NOT PINCH THE LINES ON THE LEFT (DRIVER’S) SIDE FRAME RAIL.
8. Cap with flat washers (S) and nylon lock nuts (R). Position the front upper bracket
onto the frame rail so the center hole is in the middle of the frame and there is
sufficient clearance between the fitting and the stock jounce bumper cup.
9. Torque the U-bolts to 10 lb.-ft. (14Nm). Repeat for the other side.
10. Figure 22 shows the U-bolt installed on models that have the heat shield above the axle
with spacer installed on passenger’s (right) side, forward of the axle. Continue with
Lower Bracket Installation.
For vehicles with a fifth-wheel hitch bracket that runs alongside the frame, perform
the following steps:
11. Center the upper bracket in the middle of the frame rail, make sure there is sufficient
clearance between the fitting and the stock jounce bumper cup, and drill a 5/16”
hole in the frame using the center hole in the front side of the upper bracket as a
template (fig. 23). Install the washer-head self-tapping screw (N) in the hole (fig. 24).
Torque to 15 lb.-ft. (20Nm). Repeat for the other side.

Installing the Air Lines
Air lines are routed from the air springs to Schrader valves. LoadLifter 5000 series air
lines come in two styles: nylon and braided stainless steel. Begin by choosing locations
for the Schrader valves and drill a 5/16” (8mm) hole, if necessary (Fig. 28).
KEEP AT LEAST 6” (150MM) OF CLEARANCE BETWEEN ALL AIR LINES AND THE
EXHAUST SYSTEM. AVOID SHARP BENDS AND EDGES.
INSTALLING NYLON AIR LINES
1. Cut the air line in half. Make clean, square cuts with a razor blade or hose cutter
(Fig. 29). Do not use scissors or wire cutters.
2. Use zip ties to secure the air line to fixed points along the chassis. Do not pinch or kink
the air line. The minimum bend radius for the air line is 1 ” (25mm) . Leave at least 2”
(50mm) of slack in the air line to allow for any movement that might pull on the air line.
3. Install the Schrader valve in the chosen location (Fig. 30).

Clearance test — Inflate the air springs to 40-60 PSI (2.8-4.1BAR) and make sure
there is at least 1/2” (13mm) clearance from anything that might rub against each
sleeve. Be sure to check the tire, brakes, frame, shock absorbers and brake cables.
Leak test before road test — Inflate the air springs to 40-60 PSI (2.8-4.1BAR) and
check all connections for leaks. All leaks must be eliminated before the vehicle is
road tested.
Heat test — Be sure there is sufficient clearance from heat sources, at least 6” (152mm)
for air springs and air lines. If a heat shield was included in the kit, install it. If there is no
heat shield, but one is required, call Air Lift customer service at [phone].
Fastener test — Recheck all bolts for proper torque.
Road test — The vehicle should be road tested after the preceding tests. Inflate the
springs to recommended driving pressures. Drive the vehicle 10 miles (16km) and
recheck for clearance, loose fasteners and air leaks.
Operating instructions — If professionally installed, the installer should review the
operating instructions with the owner. Be sure to provide the owner with all of the
paperwork that came with the kit.
INSTALLATION CHECKLIST
1. Check air pressure weekly.
2. Always maintain normal ride height. Never inflate beyond 100 PSI (7BAR).
3. 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.
FOR SAFETY AND TO PREVENT POSSIBLE DAMAGE TO THE VEHICLE, DO NOT EXCEED
