Introduction

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 han-dling and safety of the vehicle.
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.

Warning:

• 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 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 support the vehicle’s frame and any other heavy components.

7. Remove the front sway bar links at the axle and sway bar mounting points with the use of a 18mm socket and wrench. Retain hardware for reuse.

8. Disconnect the front brake lines from the axle using a 10mm wrench. (Note: The ABS wire may have to be unclipped from the brake line to allow the axle to be lowered to remove the coil springs.)

9. Disconnect the front axle differential vent hose from the differential housing with the use of needle nose pliers.

10. Lower the front axle slowly with the jack used to support the axle until the front coil springs become un-seated.

11. Remove the factory coil springs from the vehicle by slowly lowering the jack used to support the front axle until the coil springs can be removed. If using a coil spring compressor use caution.

12. With the front axle supported use 21mm and 24mm wrenches 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.

13. With the use of a 18mm wrench loosen the upper control arm hardware located at both the frame and axle mounts but do not completely remove until instructed. To gain access to the front upper control arm frame side hardware you will need to remove the factory heat shields with the use of a 10mm socket. Retain heat shields and hardware to be reused.

14. Adjust the supplied Rusty’s JK Wrangler Adjustable Front Upper Control Arms to the specified length in the chart below for your suspension height. (Note: The length of the control arms could need to be adjusted when the vehicle is being aligned as this is just an approximate starting length and can vary.)

50. Adjust the front drag link to in order to center the steering wheel by loosening the two bolts on the drag link adjustment collar and then and rotating the adjustment collar until the steering wheel is centered.

51. Retighten the two bolts on the drag link adjustment sleeve.

52. Readjust headlights to proper specs.

53. A professional front end alignment is required. If necessary, the vehicle can be driven to a local alignment shop, but the alignment should be performed as soon as possible.

54. Re-torque all fasteners after 500 miles and recheck after 1000 miles. Visually inspect all hardware components and retorque fasteners during routine vehicle service.

55. Installation is now complete. Cycle the steering lock-to-lock and double-check all of the components for.

Final Notes
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. Alignment specs are 7-degree positive castor, 0 camber and the toe should start at 0.

WARNING:  It is the owners’ responsibility to inspect all Rusty’s products for proper torque specs to prevent the 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 obstacles that may lie ahead. Please remember to preserve our right to enjoy public land through the proper use of off-road vehicles.
