bolt into the lower spring pad (ref. step #12). Rotate the coil to

index the spring with lower coil cup.

17. Install the spring retainer clamp removed in step #5.

18. Install longer front shocks. Bar pins may need to be put through the

bottom shock eyes (use light grease).

19. Install adjustable front track bar per instructions supplied with track

bar. Make final adjustment when weight is on vehicle and axle is

centered.

20. Install sway bar quick disconnects per instructions supplied with

disconnects (see photo 2 for typical installation).

-REAR AXLE-

21. Remove the rear shocks.

22. Remove the rear sway bar end links.

23. Support the rear axle.

24. Disconnect rear track bar at axle.

25. Remove all four factory control arms.

26. Remove the rear springs.

27. Remove the plastic dust shield that covers the bolt securing the rear

track bar to the mount on the axle housing and discard.

28. Remove the Torx head bolt (t55) and disconnect axle end of track

bar. If not done previously

29. Install track bar bracket using the supplied ½” bolt and spacer (the

spacer goes in the location vacated by the track bar to prevent the

bracket from deforming when the bolt is tightened - see photo 3 for

similar installation).

30. With the track bar bracket in place, drill two 5/16” holes in the axle

mount where the plastic dust shield was previously located, one on

top and one on angled surface.

31. Install the 5/16” hardware in the holes drilled in step #30. If

required, use supplied horseshoe shim to take up space between

bracket and axle mount at top 5/16” bolt.

32. Install the track bar in the track bar bracket using the Torx bolt

removed in step #28. It may be easier to do this later with weight

on the vehicle.

33. Set lower control arm length to 17.5” for 4.5” lift. Install the lower

control arms with the rubber bushing at the uni-body and super flex

end at the axle. The offset tube should be mounted as low as

possible (zerk on top - see photo 4). Use the factory hardware at

the uni-body and supplied bolt at the axle mount (don’t fully tighten

until vehicle is back on the ground).

34. Set upper control arm length 3/8” longer than stock for a good

starting point (see troubleshooting for drive shaft vibration/pinion

angle adjustment). Install the upper control arms using the factory

hardware (don’t fully tighten until vehicle is back on the ground).

Super flex end should be at axle with zerk on top (see photo 5).

35. Remove the rubber insert from the rear bump stop. Remove the

bump stop cup. Place the spacer between the bump stop cup and

the frame member of the uni-body using the supplied longer metric

hardware (see photo 6). Reinstall rubber bump stop.

36. Install springs. Spring compressors may be helpful.

37. Install replacement sway bar end links.

38. Install longer rear shocks.

39. If installing RE2120 transfer case drop kit (see slip yoke vibration in

troubleshooting) install it now. Support cross member with floor

jack. The cross member is factory mounted with two studs and two

bolts. The studs will have to be removed with a stud remover or by

double nutting them and backing them out. One side at a time,

lower the cross member just enough to insert the spacers at each

bolthole and install bolts and washers.

40. Install all tires.

41. Lower vehicle to ground and adjust front track bar to center front

axle per instructions supplied with track bar.

42. Thoroughly bleed brake lines and check for leaks.

43. Double-check all nuts and bolts to factory torque specs.

44. Test drive and note location of steering wheel. Adjust drag link to

center steering wheel.

45. Align vehicle as soon as practical. A good rule of thumb is minimum

factory caster and maximum factory toe-in.

46.

Recheck all bolts after 50 miles and again after every off road

excursion.
