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 help restore caster to factory specs on
3” lifted trucks
1. The control arms are the same left and right.
2. 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.
3. Reuse the factory mounting bolts. We recommend installing the axle end control arm
bolts from the inside so there is minimal rock damage to the exposed thread on the
end of the bolt.
4. Tighten the factory control arm bolts to the following specs, depending on size.
(Note, do not torque until vehicle is sitting at ride height)
14mm (9/16” bolts) – 125 ft-lbs
16mm (5/8” bolts) – 145 ft-lbs
18mm (3/4” bolts) – 200 ft-lbs
