The Pro Comp kit includes four lower-tubular control arms, a track-bar mounting bracket, sway-bar links, bumpstop pad with extension, and assorted mounting hardware. Pro Comp’s taller coil springs and MX-6 shocks are not part of the basic package, but should be installed as well for optimum performance, along with a steering stabilizer.

1. After greasing the lower control arm ends, press in the red polyurethane bushings by hand, then tap in the bronze sleeves with a soft mallet.

2. For improved control and strength, the control arms have a tubular design, instead of the stamped steel on the factory units, and are fitted with stiffer polyurethane bushings rather than soft rubber ones.

3. After making sure the suspension is well-supported, remove the stock lower control arm in the front and bolt in the longer lower control arm. Before dropping the suspension, add more slack in the brake line by unbolting the brake-line bracket. Also, remove the forward skidplate so the front driveshaft has sufficient clearance.

4. The Pro Comp springs are not only taller, but more tightly wound.

5. Next, drill a pilot hole for the bumpstop pad and thread the hole for a bolt.

6. Mechanic’s tip: Zip-tie the pad to the inside of the spring to simplify installation, so you don’t have to compress the spring to fit in above the pad. Use a pry bar to compress the spring when fitting it into the perch.

7. Bolt on the pad securely.

8. Install the longer Pro Comp MX-6 shock. Fasten the rubber boot with zip-ties after bolting the shock in place.

9. Install mounting hardware, along with bushings and sleeves, on the longer sway-bar links.

10. Then bolt the links on the factory mounts.

11. Here’s how the front suspension looks once the Pro Comp control arm, shock, spring, and sway-bar link are installed.

12. Replace stock shock for steering stabilizer with Pro Comp’s stabilizer shock.

13. After installing bushing in the end of the adjustable track bar, drill a 5/8-inch hole in the factory mounting bracket. Next, bolt on the adjustable rod end (leave the other end loose for installation later on when the vehicle is back on its wheels).

14. Here’s the toughest part of the install, way up inside the chassis. Remove the four 6mm bolts that secure the transfer-case pivot bracket to the floorpan (access them by lifting the floor carpet on the driver’s side of the cockpit). Then install shifter drop bracket into the factory mounting location.

15. The skidplate needs to be lowered for driveshaft clearance. After unbolting the air pump for the lockers from the rear skidplate, lift the pump higher up in the chassis, and zip-tie it temporarily out of way. Then remove the rear skidplate. Reinstall skidplate with spacers (bronze colored).

16. Moving to the rear, make sure the rearend is well supported, and unbolt the traction bar to allow rear suspension to droop and then remove the shock, spring, and control arm from each side. Then install the Pro Comp control arm in the factory mount.

17. Bolt on the bumpstop spacer and install the new Pro Comp lift spring.

18. The spacer bracket for the track bar bolts on, but additional bolt holes need to be drilled as well. The bracket fits in a tight spot; patience is required to secure it properly.

19. Remove the stock end links for the sway-bar and replace them with the longer Pro Comp units.

20. The Pro Comp shocks bolt right into the factory mounts.

21. The Pro Comp Mud Terrain tires (305/70R16) and the new, 16x8” Xtreme Alloy Series 1023 wheels do a nice job filling up the wheelwells. (Note that this larger tire won’t fit on the factory mount for the spare, but there’s a conversion kit available through 4Wheel Parts to change the upper brake light and rear bumper.)

22. Here’s how the rearend should look after the Pro Comp lift kit is installed.

23. Once the vehicle is back on its wheels, don’t forget to attach the passenger side of the track bar.

24. Also, be sure to have the alignment checked and adjusted as well.
