XRAY 302979 Aluminium Rear Fixed Shock Holder +1mm — X4F Swiss 7075 T6 (2 pcs)  [XR-302979]

Rear fixed shock holder for X4F

This is an RC-scale rear fixed shock holder designed to alter shock geometry in small, repeatable steps. The holder raises the shock mount by +1mm to increase suspension travel, and it accepts thin shims to refine the shock angle in more precise increments.

Construction uses Swiss 7075 T6 aluminium with a black anodized finish, supplied as a set of 2 pcs for the rear end. The part provides three selectable flex positions to influence local mount stiffness and tune rebound behavior without changing the shock or spring package.

Installation is straightforward: replace the existing rear shock holder with this piece, orient the mount to the required flex position, then add or remove shims to achieve the desired shock angle and travel. Check alignment and clearances after fitting to ensure the shock shaft moves freely through the full stroke.

Use this holder to fine-tune rear suspension geometry on X4F platform cars, trading small changes in shock angle and travel to dial handling and traction without swapping major components.
