XRAY XR363321 Aluminium Rear Lower Holder +2, 7075‑T6

The XRAY XR363321 Aluminium Rear Lower Suspension Holder +2 (Rear) is a precision 7075‑T6, 5mm component designed for high‑grip conditions. Recommended for carpet and other high‑traction tracks, it helps the car rotate more freely and drive more cleanly through corners. Part number XR363321 ensures an exact match to XRAY’s racing specification.

This holder integrates XRAY’s I.S.S. (Integrated Suspension Settings) concept. By using eccentric suspension bushings within the aluminium block, together with additional suspension shims, suspension geometry can be adjusted quickly and consistently. First introduced on the XB8 and adapted for the 1/10 XB4 platform, I.S.S. makes trackside tuning fast and repeatable.
