PPM-8052 JK REAR LOWER CONTROL ARMS
Instructions
GENERAL NOTES
• These instructions are also available on our website: www.synergymfg.com. Check the
web-site 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 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 come 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 lower control arms. For 3-4.5” of lift,
we recommend a length of 20.25” measured from the center to center of the bushings.
This length works well when using the stock length upper control arms and for longer
upper control arms when using a CV style rear drive line. If you need to point the pinion
up to use a CV style rear driveline, try to only lengthen the upper arms and leave the
lowers at 20.25”.
3. Remove the existing lower control arms. If you are just replacing the lower control
arms, they can be replaced one at a time with the vehicle sitting on level ground, without
removing the tires & wheels or any other suspension part.
4. Install the new control arms with the bushing at the axle end and the flex joint at the
frame end. Position the arm with the pinch bolt and the grease zerk in the flex joint on the
top of the control arm. Reuse the factory mounting bolts.
5. Tighten the factory control arm bolts to 125 ft-lbs, once final length adjustments are
made, tighten the pinch bolt to 80 ft-lbs.
6. Grease the flex joints using extreme pressure moly based grease.
