INSTALLATION INSTRUCTIONS
Last Revised: 1.10.18

Introduction:

Read instructions several times before starting. Be sure you have all the needed parts and know where they  install. Read each step completely as you go. Exhaust modifications may be necessary. Prior to drilling or  cutting, check behind the surface being worked on for any wires, lines, or hoses that could be damaged.  After any drilling or cutting, remove burrs and grind smooth any surfaces. An inclinometer or similar tool  may be needed to measure driveshaft angles before and after the installation. Rusty’s recommends that this installation be performed by a certified automotive technician or a person  with professional mechanical knowledge. Installing this kit without this expertise may jeopardize the handling and safety of the vehicle.

Warning:

  • Seat belts and shoulder harnesses should be worn at all times.
  • It is the owners’ responsibility to inspect all Rusty’s products for proper torque specs to prevent loosening of components.
  • Re-check all bolts and nuts after the first 100 miles and after any off-road usage during the first 300 miles.
  • Although all of our products are made from the highest quality materials possible, they are not a substitute for Safe and Careful driving. In other words, have good safe on-road / off-road sense. Know the terrain, the speed limitations, and any obstacles that may lie ahead. Please remember to preserve our right to enjoy public land through the proper use of off-road vehicles.

Before Starting Installation:

  1. Carefully Read all warnings and instructions completely before beginning.
  2. Verify all parts have been received in this kit by checking the parts list on page#2 of this document.
  3. Only install this kit on the vehicle for which it is specified.
  4. Park the vehicle on a clean, dry, flat, level surface and block the tires so the vehicle cannot roll in either direction.
  5. Be certain the vehicle is safely secured on jack stands or a vehicle lift prior to working around or under a vehicle. Never rely on a jack alone to support a vehicle’s weight; use appropriately rated stands to sup-

Front Installation Instructions

  1. Raise vehicle and place jack stands under the frame. Chock the rear tires to prevent any accidental movement. Note: Save all factory components and hardware for reuse, unless noted.
  2. Remove the tires and wheels.
  3. Remove the stock shock absorbers using a 15mm wrench. The stock bolts and nuts on the bottom of the  shock will be reused. (Note: In order to access to the upper shock studs will be obtained through the en gine compartment. It also may be necessary to temporarily remove the washer fluid reservoir to access  the driver side upper shock mount nut.) 
  4. Remove the sway bar links on both sides using a T-55 Torx bit /19mm wrench and a 15mm for the upper  nut.
  5. Support the front axle with the floor jack.
  6. Remove the track bar from the axle housing on passenger side using a 15mm wrench. Retain factory bolt  and flag nut for re-use.
  7. Remove the factory coil spring retainer clips with a 13mm wrench. Retain the hardware for re-use.
  8. Slowly lower the jack used to support the front axle until the coil springs can be removed. If using a coil  spring compressor use caution! (Note: Use caution to not overextended the brake lines, if needed you  can remove the brake calipers from the rotors to allow the axle to be lowered further. If you remove the  brake calipers do not let allow them to hang from the brake lines as this may cause damage to the lines  or fittings. We suggest using a bungee cord or similar device to hold the caliper up out of the way tempo rally.)
  9. With the front axle supported use a 21mm wrench to remove the mounting hardware for the factory  front lower control arms at the lower control arm axle and frame mounts. Retain factory hardware, as it  will be reused.
  10. With the front axle lowered, install the supplied front coil springs. (Note: Make sure to seat the coil  spring wrap into the lower spring cup. 
  11. Reinstall the factory coil spring retainers with a 13mm wrench.
  12. Install the supplied 16-1/4”fixed lower control arms with the short side bend at the axle end to clearance  the lower axle control arm mount as illustrated below using the factory hardware. (Note: If you upgraded  to the optional Rusty’s adjustable lower control arms adjust them to 16-1/4” center hole to center hole,  and install the fixed end of the control arm at the axle mount and the adjustable end is positioned at the  frame mount.)

Lower Control Arm Measurement: 16-1/4” Center to Center Length

  1. Remove the driver side upper control arm by removing the factory hardware at the upper control arm  axle and frame mounting points. Retain factory hardware, as it will be reused. (Note: This is a great time  to inspect and replace the axle housing upper control arm bushings if needed, however, removal is not  needed for installation of this suspension kit.)
  2. Install one of the supplied fixed upper control arms using the factory hardware. The axle side mounting  point of the supplied fixed upper control arms will have two offset mounting holes. Measure from the  center of the hole in the fixed bushing end to both mounting holes in order to determine which  mounting point is correct for your lift height. For the installation of this kit, you will use the shorter dis tance of 15-1/4” center hole to center hole. Refer to the image below for correct installation orientation.  (Note: Install the fixed upper control arm so that the extra mounting hole is positioned above the hole  used to mount the control arm to the axle mount.) Axle Side Frame Side Upper Control Arm Measurement: 15-1/4” Center to Center Length
  3. Repeat steps 13-14 on the passenger side of the vehicle.
  4. The caster adjustment bolts on the lower control arm frame mounts can be adjust if needed to add more  castor. However the final alignment should be preformed by a professional alignment shop.
  5. Install the track bar in the factory location axle mount using factory hardware. Do not attach the frame  end of the new track rod at this time. Installation is to be completed once the vehicle is lowered to the  ground using the instructions provided with the adjustable front track bar.
  6. Install the supplied Rusty’s front shocks into their upper mounting position with the supplied hardware.  (Torque to 17 ft. lbs.) (Note: It is a good idea to take a wire brush and clean any excess paint from the  threads on the stud to prevent the nut from tightening properly.)
  7. Install the lower end of the shock to the axle using the factory hardware. (Torque to 20 ft. lbs.)
  8. Install the supplied Rusty’s Forged Adjustable Sway Bar Quick-Disconnects and install using the supplied  instructions.
  9. Reinstall the wiper reservoir if removed.
  10. Install the front wheels and tires. Jack up the vehicle, remove jack stands and lower the vehicle to the  ground.
  11. At this time refer to the supplied instructions with the Rusty’s front adjustable track bar and complete  the adjustment and installation of the track bar. 
  12. Front installation is completed!

Rear Installation Instructions

25. Remove the factory shocks, keeping the hardware and discarding the old shocks.

26. Raise rear of the vehicle and place jack stands under frame. Chock the front tires to prevent any accidental  movement.

27. Remove the tires and wheels.

28. Remove the clip that fastens the rear brake line to the factory bracket. Pull the brake line towards the axle  until it drops out of the factory bracket.

29. Support the rear axle with a floor jack.

30. Unbolt the U-bolts and carefully lower the axle by lowering the floor jack slowly. Retain the U-bolt plates  for reuse. (Note: Use caution not to over extend the rear brake line.)

31. Unbolt the leaf springs at the front frame mounting points and remove the lower rear shackle bolts using a  21mm wrench. (Note: Inspect the hardware once removed and replace if needed.)

32. Remove the factory spring packs and discard.

33. Grind or cut off the excess length of rear bumper bolt that is located directly behind the shackle at the  frame mounting point in order to allow more clearance when the shackle pivots towards the rear of the  vehicle. Refer to the image below.

Grind or cut off the excess length   of this bolt.

34. Install the new spring packs with the factory hardware removed in step 27; it’s a good idea to grease the  threads on the spring bolts, mount the frame end first and then the shackle. Jack up axle into position, be  sure to align center pins. (Note: Do not torque hardware until instructed.)

35. Slowly raise the axle up into position and be sure the center pins align with the holes in the axle pads on  each side.

36. Position the supplied U-bolts and factory spring plates into position. Install a flat washer followed by the  nut then tighten the hardware. (Torque to 75 ft. lbs.)

37. Install the bushings and sleeves in the new Rusty’s shocks. Install them on the vehicle with the factory  hardware. (Torque upper bolts to 18 ft. lbs. and lower bolts to 40 ft. lbs.) (Note: Please note the orientation of the rear shocks.

CORRECT:

Mount RX-100 series shocks with the body down and   shaft pointing up.

38. Reinstall the tires and wheels and lower vehicle.

INCORRECT:

DO NOT MOUNT RX-100 Series  Shocks with the Shaft pointing  towards the ground. This will  cause poor handling and ride  quality.

39. Remove the jack stands and lower the vehicle to the ground.

40. Tighten the leaf spring and shackle hardware to the torque specifications. (Torque the frame bolts to  100 ft. lbs. and shackle bolts to 25 ft. lbs.)

41. Tighten the lug nuts to the factory torque specifications.

42. Install the Rusty’s Rear Stainless Steel Brake Hose using the supplied instructions. 43. Install the supplied Rusty’s Transfer Case Drop Kit using the supplied instructions. 44. Installation Completed!

Alignment Recommended Specifications At this point there should be no parts left but installing the stickers. The vehicle will need to have an alignment as soon as possible, if you don’t you may get the “death wobble”, poor tire wear or just a bad handling  vehicle.

  • Toe: Should be set at 0 to 1/32” Toe Out
  • Castor: 7.5 Degrees Positive
  • Camber: 0

Tighten hardware to torque specifications called for the components below with the vehicle resting at ride  height to prevent preloading any of the joints or bushings.

  • Control Arms
  • Leaf Springs
  • Shackles
  • Track Bars

It is the owners’ responsibility to inspect all Rusty’s products for proper torque specs to prevent loosening of  components. Seat belts and shoulder harnesses should be worn at all times. Re-check all bolts and nuts after  the first 300 miles and after any off-road usage during the first 300 miles. Although all of our products are  made from the highest quality materials possible, they are not a substitute for Safe and Careful driving. In  other words, have good safe on-road / off-road sense. Know the terrain, the speed limitations, and any obsta cles that may lie ahead. Please remember to preserve our right to enjoy public land through the proper use of
