Race-Grade Rear Shock Mount for XB4 2021

The XRAY 363085 rear graphite shock tower fits the XB4 2021 HS chassis and is manufactured from 3.5mm graphite for a strong but light component. Its design tightens the upper shock mounting geometry to give clearer suspension feedback for lap-to-lap consistency.

Flexible Mounting for Track Tuning

This tower offers multiple roll centre options and extra wing mounting holes to tailor balance and downforce, making it straightforward to adapt the car to different grip conditions.

Specifications

  • Material: Premium-grade 3.5mm graphite
  • Compatibility: Fits XB4 2021 series
  • Features: Multiple shock and roll center positions

A solid upgrade for drivers wanting tighter handling control and more setup permutations on a variety of surfaces.
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.

Is this compatible with all XB4 variants?

This tower is made for the XB4 2021 series using the Horizontal Split Bulkheads configuration; confirm your chassis revision before fitting.

Does the graphite thickness make a big difference?

The 3.5mm graphite increases stiffness compared to thinner plates, which can sharpen turn-in and reduce unwanted flex under load.

Can I use my current wing mounts?

The extra wing mounting positions expand options, and in most cases existing wing hardware will work with the new tower layout.

Any setup tips for street circuits?

Try a higher roll centre and stiffer rear springs to reduce mid-corner understeer on abrasive street surfaces.
