1x Pair of Rear upper arms
The GKTech Z33 350z Rear upper camber arms give you the ability to adjust and tune your vehicle's rear camber.
When you lower your car negative camber is introduced. This reduces the contact patch of your tyres and thus available traction. Our rear camber arms are a direct replacement of the OEM arm and will correct this issue.
- Feature high quality Teflon lined pillow ball spherical bearings which eliminate the flex found in factory rubber bushing offering a more direct and predictable feel.
- 4130 Chromoly construction
- fixed On car adjustment points with no need to remove the arm to adjust
- +/- 10mm of adjustment equated to approximately +/- 2.25 degrees of adjustment
- Retains factory swaybar mount point
- Unique design that doesn't have REIB for maximum strength
