1. Prior to installing this kit, with the vehicle on the ground, measure the heights of your vehicle. This measurement can be recorded from the center of the wheel straight up to the top of the inner fender lip. Record the measurements.

LF:__________ ,RF:___________, LR:__________, RR:___________

2. Place vehicle in park and chock the rear wheels. Using a 21mm socket, remove bolt securing the front track bar to the frame. Retain stock hardware. See Photo 1. Raise the front of the vehicle with a jack and secure a jack stand beneath each frame rail behind the front control arms. Ease the frame down onto the stands. Support the axle with a floor jack.

3. Remove the front tires/wheels, using a 19mm deep well socket.

4. Using a 18mm socket and wrench remove the bottom sway bar bolts. See Photo 2.

5. Using an 18mm socket and 19mm wrench, remove the top of the sway bar link.

5. Remove the front factory skid plate with a 18mm socket.



6. Remove the lower shock bolt using a 18mm socket and wrench. Using a 14mm wrench unbolt the top of the shock and remove. See Photo 3. Retain stock hardware.

7. On some models it will be necessary to remove the brake line bracket from the frame to allow the coils to be removed. Using a 10MM socket, remove the brake line bracket from the stock location.

8. Lower the axle with the floor jack to allow room for the coils to be removed. Remove stock coil springs. Retain upper coil isolators.

9. Remove the bolts securing the upper control arms to the axle and frame using a 18mm wrench/socket. It may be necessary to cut out the passenger side upper bolt as shown in Photo 4 to remove the control arm. A new bolt is supplied in the hardware bag to replace this factory bolt. Retain factory axle end hardware.



12. Next the upper and lower factory control arm pocket have to be removed to make clearance for the longer arms. This will be done using a plasma cutter or cut off wheel in a die grinder. Always use gloves and safety glasses.

13. First cut half of the lower control arm pocket on the passenger side as shown in Photo 5. Follow around the bottom edge where the bracket tapers down to the frame. Be careful not to cut through the frame. In Photo 6 you can see where the first cut is made.

POST INSTALLATION

IMPORTANT NOTE : The draglink must be adjusted to the center steering wheel BEFORE the vehicle is driven. Failure to do so will cause a computer error, odd handling, and poor performance

1. Adjust front draglink to center the steering wheel before driving by loosening the two bolts and turning the adjustment collar. See Photo 1 & 2

2. Check all fasteners for proper torque. Check to ensure there is adequate clearance between all rotating, mobile, fixed and heated members. Check steering for interference and proper working order. Test brake system.

3. Perform steering sweep. The distance between the tire sidewall and the brake hose must be checked closely. Cycle the steering from full turn to full turn to check for clearance. Failure to perform inspections may result in component failure.

4. Re-torque all fasteners after 500 miles and recheck after 1000 miles. Alignment must be checked by a qualified mechanic. Visually inspect components and re-torque fasteners during routine vehicle service.

5. Readjust headlights to proper settings.

6. Have a qualified alignment center realign the front end, to the factory specifications immediately.

Caster preferred 4.6 degree range ,- 1 degree
Camber preferred –0.25 degree range ,- 0.63 degree
Toe-in preferred 0.15degree range ,- 0.15 degree
