Shop Parts in this Guide

Kit Includes:
2 front bumpstop extensions (1.75" OD x 1.5" tall)
2 bolts (10mm x 55 mm) for front bumpstops
2 rear bumpstop extensions (1.75" OD x 2" tall)
2 bolts (10mm x 65mm) for rear bumpstops
4 spring spacers


1. Jack up the vehicle by the frame and secure it with jack stands.

2. Remove the shocks.

3. Remove the rubber bump stops by grasping the bump stops and pulling down with a side to side motion.

4. Use a 15mm socket to remove the bolt inside both bump stop cups.

5. Remove the springs.

6. With 16mm socket and new bolt (10mm x 55mm 1.5 pitch) replace the bump stop cup placing the spacer between the bump stop cup and the bump stop pedestal.

7. Reinstall the springs, placing black spring spacers above the springs.

8. Reinstall shocks.

The rear of many TJs sits higher than the front. Combining spring spacers with the factory rubber insulator on the TJs front will provide closer to two inches of additional lift to help level the vehicle out.


Adverse handling characteri­stics and drive line angles may result when combining 1.25 or 1.5-inch spring spacers with aftermarket lifts. The use of any spring spacer in addition to TeraFlex suspension systems will void any warranty claims on TeraFlex springs.
