XRAY 343047 Graphite 3.5mm Rear Upper Arm Holder - Race Tune  [XR-343047]

Precision Graphite Rear Upper Arm Support

The XRAY 343047 Graphite Rear Upper Arm Holder is a precision machined component built to refine rear suspension compliance. Fabricated from 3.5mm graphite, it provides a measured balance between rigidity and controlled flex for competitive driving.

Geometry Improvements for Sharper Handling

This rear upper arm holder features relocated eccentric bushing positions that allow the upper hinge pins to sit 2.5mm closer together. That change pairs with a narrower rear lower arm mount layout to help fine tune roll behaviour while the front and rear mounts remain anchored to the upper clamps for secure attachment under load.

Fitment Notes and Installation

Suited for cars with narrower rear bulkheads, this holder installs with standard hardware and keeps suspension alignment predictable. Correct fit ensures the rear end reacts consistently, aiding traction and corner exit stability.
