Rear fixed shock holder tailored to X4F setups

This RC-scale rear fixed shock holder is made to change shock geometry in controlled, repeatable steps. The mount raises the shock position by +1mm to free up additional suspension travel and accepts thin shims so you can fine-tune the shock angle in small increments.

Machined from Swiss 7075 T6 aluminium and finished in black anodize, the part is supplied as a set of two pieces for the rear end. It offers three selectable flex positions to alter local mount stiffness and influence rebound response without changing springs or shock internals.

Fitting is simple: remove the original rear shock holder, fit this component, select the desired flex position, then add or remove shims to reach the target shock angle and travel. After installation, verify alignment and clearances so the shock shaft can travel through its full stroke unimpeded.

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

How does the +1mm rise affect travel and leverage?

Raising the mounting point by +1mm increases available vertical travel and slightly changes leverage on the shock shaft, producing modest differences in compression and rebound feel that can be used to tune ride height and initial compliance.

What is the purpose of the thin shims?

Thin shims go between the holder and chassis to alter the shock angle in fine steps. They let you adjust roll center and shock leverage precisely without changing shock mounts or using different-length shock bodies.

What are the material and finish benefits?

The component is CNC machined from Swiss 7075 T6 aluminium for high strength-to-weight and finished with black anodize to resist wear and corrosion under track conditions.

Will this fit every X4F rear configuration?

This holder is designed for X4F rear end arrangements. Confirm the chassis mounting points and clearances on your specific X4 series rear setup before final installation to ensure proper fit and shock travel.
