6. Reuse the factory mounting bolts.
**NOTE** 8553-01 control arms feature joints which utilize 14mm (9/16”) hardware.
If vehicle is equipped with 12mm (1/2”) hardware, drill out factory control arm mounts to
9/16” and source new Gr8 mounting hardware or factory 14mm bolts for installation.
7. Tighten the factory control arm bolts to the following spec:
14mm (9/16” bolts) – 125 ft-lbs
8. Adjust upper arms for proper caster setting; between 5.0-8.0 degrees depending on preference. For a 3”
lifted vehicle, we recommend the following control arm lengths for proper axle location and caster setting:
Front Lower Control Arm: 19”
Front Upper Control Arm: 17”
9. Once satisfied with control arm lengths, tighten pinch bolt to 50 ft-lbs. Make sure the bushings are neutral
in the mounts at ride height prior to tightening the pinch bolts.
Installation is Complete
