XRay Aluminium Rear Lower 1 Piece Suspension Holder - Rear - Black - Rr

The XRay XR333722 Aluminium Rear Lower 1 Piece Suspension Holder (Rear) is a CNC-machined component for the rear of the rear bulkhead, produced from premium Swiss 7075‑T6 aluminium with a black finish. It retains the well‑proven NT1 geometry while providing durable, precise mounting of the rear suspension arms.

Redesigned rear arm mounts accept square composite eccentric bushings derived from XRAY’s T4 and XB4 platforms. This preserves vertical inner hinge pin adjustment and adds pin‑width tuning, expanding roll centre and geometry options. The narrower holder allows the arms to be mounted closer together for increased traction and a smoother feel through corners. The mounting system enables the arms to move very freely, improving cornering consistency.
