CNC Aluminum Rear Suspension Holder for XRAY T4

The XRAY 303720-O Aluminum Rear Lower Suspension Holder is CNC machined to improve the rear suspension support of your XRAY T4. Constructed from Swiss 7075 T6 aluminum, it mounts at the rear bulkhead to give a strong but light foundation for the suspension arms.

Built for Consistent Setup

This holder incorporates Integrated Suspension Settings (ISS) so you can make fast, repeatable geometry adjustments. The ISS concept, proven on the XB8, has been scaled to fit 1/10 on-road layouts to help keep alignment after minor impacts.

Better Traction and Corner Control

The precise CNC finish helps suspension arms pivot smoothly, improving traction and cornering balance. That smoother movement also sharpens steering response, useful for drivers chasing consistent lap times.
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 XRAY 303720-O fit every T4 variant?

Yes. The XRAY 303720-O is designed to match the mounting points of XRAY T4 models and replaces the standard rear lower suspension holder for a direct upgrade.

What is the material and why does it matter?

It is machined from Swiss 7075 T6 aluminum, which offers a high strength-to-weight ratio. That material keeps the hub rigid while minimizing added mass at the rear.

Any tips for installing and setup?

Use the original T4 mounting hardware and verify arm movement after installation. Start with your baseline ISS position and make small adjustments to suit track traction and steering feel.
