Fixed rear shock bracket for precise X4F tuning

This rear fixed shock bracket is engineered to shift shock geometry in small, repeatable steps. By raising the mount +1mm it increases suspension travel range and accepts thin shims so you can micro-adjust the shock angle.

Constructed from Swiss 7075 T6 aluminium with a black anodized coating, the item is supplied as a pair for the rear end. The design provides three different flex positions to affect local mount stiffness and tune rebound characteristics without altering the spring or damper internals.

Installation is direct: remove the existing rear shock holder, fit this piece, select the flex position you need, and then add or remove shims to set the precise shock inclination and travel. Always check that the shock shaft clears the whole stroke after fitting.

Fit this holder to dial in the rear geometry on X4F-platform cars, tuning small angle and travel changes to improve balance and traction without swapping shocks.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will the +1mm change weaken the setup?

No. The +1mm adjustment is small and the part's 7075 T6 construction maintains strength. The change alters leverage modestly rather than compromising mount integrity.

How fine are the shim increments?

Using thin shims allows very small angle changes. This makes it possible to step the shock angle in subtle increments for sensitive roll center and leverage adjustments.

What finish is applied to the part?

The holder is black anodized after machining to help resist corrosion and surface wear during routine use.

Do I need other parts to fit this on an X4F?

It is intended to replace the stock rear holder directly on X4F rear ends. Check your mounting hardware and clearances; standard fasteners and shims are typically sufficient.
