Installation requires a professional mechanic. The overall vehicle must be in
excellent working condition; repair or replace all worn parts.
Read instructions several times before starting. Be sure you have all needed
parts and know where they install. Read each step completely as you go.
NOTES:
- The ball joints DO NOT come pre-greased—They MUST be greased prior to installation.
- Front end alignment is necessary.
- A foot-pound torque reading is given in parenthesis ( ) after each appropriate fastener.
- Do not fabricate any components to gain additional suspension height.
- Prior to drilling or cutting, check behind the surface being worked on for any wires, lines, or hoses that could be damaged.
- After drilling, file smooth any burrs and sharp edges.
- Prior to attaching components, be sure all mating surfaces are free of grit, grease, excessiveundercoating, etc.
- A factory service manual should be on hand for reference.
FRONT INSTALLATION
Save all factory components and hardware for reuse, unless noted.
-
Place vehicle in neutral. Raise front of vehicle with a jack and secure a jack stand beneath each frame rail, behind the lower control arms. Ease the frame down onto the stands, place transmission in low gear or “park”, and chock rear tires. Remove front tires.
-
Disconnect the battery.
-
Remove front splash guard; mark the skid plates (driver and passenger) then remove.
-
Loosen the two control arm bolts.
-
Remove the nuts securing the tie rod ends to the knuckle. Using the appropriate puller tool, separate the tie rod end from the knuckle.
-
Measure and record the amount of exposed threads above the nut on the anti-sway bar link. On each side, loosen and remove the bushings and hardware attaching the anti-sway bar link to bar body.
-
Support the lower control arm with a jack as not to interfere with the removal of the lower bolts.
-
Mark the location of each strut (driver and passenger side) as well as the outermost stud of each strut for later reference during re-assembly.
-
Remove the two bolts securing the strut to the lower control arm, followed by the three nuts securing the strut to the frame. Remove the strut while taking precautions not to damage any other vehicle components.
-
Mark the position of the alignment cam bolt washers on the frame.
-
Disconnect the brake line bracket from the upper control arm.
-
With the control arm still supported with a jack. Remove the upper ball joint nut and, using the appropriate puller tool, separate the upper control arm ball joint from the knuckle.
-
Remove the upper control bolts and remove the upper control arm from the vehicle.
-
Install the new upper control arm (55-11-3600/3700 driver side and 55-12-3600/3700 passenger side)in the frame using the factory hardware. Do not tighten at this time. NOTE:
NOTE: Grease the ball joint prior to installation. -
Using a cutoff wheel or similar tool, trim the (3) OE Strut studs down to the top most thread.
-
Insert 10mm carriage bolts into the top of the strut spacer (#55-23-3600). Slide push nut onto the carriage bolts to hold bolts in place for installation.
-
Attach the strut spacer to the top of the strut assembly using supplied 10mm flange nuts. Tighten the flange nuts (40).
-
Attach the lower end of the strut to the lower control arm using the factory hardware in the forward hole and the supplied 10mm x 65mm bolt in the rearward hole.
-
Tighten the 10mm carriage bolts at the top with the stock nuts (45) and the factory hardware at the bottom (40) of the strut assembly.
-
Connect the new control arm to the steering knuckle using the supplied castle nut and cotter pin.
-
Connect the factory brake line bracket to the upper control arm with the supplied 1/4” self-tapping bolt. Note: The bracket may need to be bent slightly to start the bolt; it can be bent back to the original position once the bolt is tightened.
-
Attach the tie rod end to the knuckle using the factory nut and tighten (44).
-
Reattach the anti-sway bar links to the lower control arm and the anti-sway bar body. Tighten until the exposed thread dimension previously recorded is reached.
-
Mark on the rear crossmember the spot where the front differential is the closest to the rear crossmember.
-
Remove the rear crossmember. Support the differential with a jack and remove the rear differential bolts.
-
Carefully lower the differential enough to install the new thin spacers (55-06-3600) between the frame and the differential mount and secure using the factory hardware; do not tighten at this time.
-
Remove the front differential bolts and lower the differential down to enough to install the thick spacers (55-05-3600) between the frame and the differential mount and secure the supplied 12mm bolts and factory nuts; do not tighten at this time.
-
Tighten the rear differential bolts and then the front. (75) It is important to tighten the rear differential bolts first to ensure proper alignment of the differential.
-
Using the marks made earlier on the rear crossmember as a guide, use a hammer to form a slight depression in the crossmember to allow for clearance around the differential. The depression should be about 1/8” deep.
-
Reinstall the rear crossmember using the factory hardware. (154). Make sure the differential is no closer than 1/8” from the factory rear crossmember.
-
Reuse the factory 10mm bolts removed from the upper splash shield and secure the new belly pan (55-04-3600) to the frame. The belly pan uses two (2) bolts in the front and one (1) in the rear. (40)
-
Reinstall the plastic splash guard by using the factory hardware at the top and the supplied 10mm x 35mm bolts at the bottom. (30)
-
Install the factory passenger side skid plate; placing the supplied spacers (#1-26-7055) between the skid plate and the crossmember. Secure using the supplied 10mm x 35mm bolts. (40)
-
Reinstall the plastic splash guard by using the factory hardware; only one bolt will be used to attach it to the driver’s side skid plate. (30)
-
Reinstall the tires and wheels. Tighten the lug nuts (95) in the sequence shown. 36. When the tires / wheels are installed, always check for and remove any corrosion, dirt, or foreign material on the wheel mounting surface, or anything that contacts the wheel mounting surface (hub, rotor, etc.). Installing wheels without the proper metal-to-metal contact at the wheel mounting surfaces can cause the lug nuts to loosen and the wheel to come off while the vehicle is in motion.
-
Retighten lug nuts at 500 miles after any wheel change, or anytime the lug nuts are loosened. Failure to do so could cause wheels to come off while vehicle is in motion.
-
With the vehicle still on jack stands, and the suspension “hanging” at full extension travel, check all components for proper operation and clearances. Pay special attention to clearance between the tires / wheels and brake hoses, driveshaft, etc.
-
Lower vehicle to the floor.

- Reinstall the coil spring and raise the axle enough to hold the coil spring in place.
- Place the new shock bracket (55-31-3600 driver side, 55-32-3600 passenger side) into the axle mount.
- Use the factory shock hardware in the factory location to loosely secure the new shock bracket.
- Use the supplied 7/16” carriage bolt and flange nut in the forward hole to secure the new shock bracket to the axle mount. Tighten. (52)
- Tighten the factory shock bolt. (115)
- Install the shock into the new bracket and secure using the supplied 9/16” hardware. Tighten. (115)
- Place the new bump stop spacer (55-35-3600) on the axle mount and insert the supplied 3/8” bolt through the bracket and the axle mount.
- Place the supplied 3/8” flange nut into the supplied flange nut holder (55-36-3600) and from the rear of the vehicle over the link arm, slide the holder with the nut over the axle and start the nutonto the bolt. Once the nut is snug, remove the flange nut holder and tighten the bolt. (33)
- If equipped with air shocks, very carefully remove the plastic 90 degree fittings from the factory links and install them onto the new supplied link arm (55-34-3600).
- Reinstall the new link arm assembly into the vehicle into the factory location.
- Reattach the brake hose bracket to the axle using the factory hardware.
- Attach the ABS clip back to the frame in the factory location.
- Reconnect the sway bar link to the sway bar body.
- Reinstall the tires and wheels. Tighten the lug nuts (95) in the sequence shown.
- When the tires / wheels are installed, always check for and remove any corrosion, dirt, or foreign material on the wheel mounting surface, or anything that contacts the wheel mounting surface (hub, rotor, etc.). Installing wheels without the proper metal-to-metal contact at the wheel mounting surfaces can cause the lug nuts to loosen and the wheel to come off while the vehicle is in motion.
- Retighten lug nuts at 500 miles after any wheel change, or anytime the lug nuts are loosened. Failure to do so could cause wheels to come off while vehicle is in motion.
- Check all hardware for proper torque specifications.
- With the vehicle on the ground, check all components for proper operation and clearances. Pay special attention to the clearance between the tires / wheels, brake hoses, wiring, etc. Check tire/ wheel clearance with the fenders/bumper as well as with the steering knuckle.
- Realign vehicle to factory OEM specifications. It is necessary to have a proper and professional wheel alignment performed by a certified alignment technician. Align the vehicle to factory specifications. It is recommended that your vehicle alignment be checked after any off-road driving.

IMPORTANT PRODUCT USE AND SAFETY INFORMATION / WARNINGS
As a general rule, the taller a vehicle is, the easier it will roll over.
Offset, as much as possible, what is lost in rollover resistance by increasing
tire track width. In other words, go “wide” as you go “tall”; always use as
wide a tire and wheel combination as feasible to enhance vehicle stability. We
strongly recommend, because of rollover possibility, that the vehicle be
equipped with a functional roll bar and cage system. Seat belts and shoulder
harnesses should be worn at all times. Avoid situations where a side rollover
may occur.
Generally, braking performance and capabilities are decreased when
significantly larger / heavier tires and wheels are used. Take this into
consideration while driving. Also, changing axle gear ratios or using tires
that are taller or shorter than factory height will cause an erroneous
speedometer reading. On vehicles equipped with an electronic speedometer, the
speed signal impacts other important functions as well. Speedometer
recalibration for both mechanical and electronic types is highly recommended.
Do not add, alter, or fabricate any factory or aftermarket parts to increase
vehicle height over the intended height of the SUPERLIFT® product purchased.
Mixing component brands is not recommended.
