PPM-8054 JK REAR UPPER CONTROL ARMS

Version 1.1

GENERAL NOTES:

• These instructions are also available on our website; www.synergymfg.com.

Check the website before you begin for any updated instructions and additional

photos for your reference.

• The installation of these control arms will allow you to correctly align the rear

axle and pinion angle after a suspension lift kit is installed.

• These control arms feature a double adjuster sleeve which allows you to adjust the

length of the arm without removing the arm from the vehicle.

1. The control arms are pre-assembled to the shortest length. Make any length

adjustments by only turning the adjuster sleeve so there is equal thread on the flex

joint and adjuster sleeve. Make sure the grease zerk on the flex joint is aligned with

the pinch bolt on the control arm.

2. We recommend that you preset the length of the upper control arms before

installation. We assume you are also using adjustable lower control arms and are

installing these upper control arms to point the pinion up for the installation of a CV

style rear driveline. We recommend that the lower control arms be set to a length of

20.25” center to center of the bushings. The length of the uppers will depend on the

desired pinion angle; the following table will give you a good starting point to set the

length of the upper control arms. Pinion angle adjustment should be made with the

upper control arms, keep the lower at 20.25”.

3. Remove the existing upper control arms.

4. Install the new control arms with the bushing at the frame end and the flex joint at the

axle end. Position the arm with the pinch bolt and the grease zerks on the bottom of

the control arm. Reuse the factory mounting bolts.
