Precision 7075 Aluminium Rear Holder for XRAY T4

The XRAY 303720-O Aluminum Rear Lower Suspension Holder is engineered to reinforce the rear bulkhead area of the XRAY T4. Machined from Swiss 7075 T6 aluminium, it gives a stiff, lightweight mounting point for the rear suspension components.

Consistent Geometry with ISS

Built with Integrated Suspension Settings (ISS), this component enables quick adjustments and repeatable geometry settings. The ISS system was carried over from the XB8 and adapted specifically for 1/10 on-road applications to improve setup consistency.

Smooth Articulation for Improved Grip

The fine CNC finish allows suspension arms to articulate with minimal binding, increasing traction and smoothing cornering behaviour. Drivers will notice steadier steering input and improved predictability on fast sections.
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.

Which T4 models will accept this holder?

The XRAY 303720-O is compatible with T4 chassis that use the standard rear bulkhead mounting layout, making it suitable for a wide range of T4 variants.

Does the material affect handling?

Yes. Using Swiss 7075 T6 aluminium increases stiffness at the mounting point, which can reduce flex and help maintain consistent suspension geometry under load.

How should I set up ISS positions?

Start from your normal baseline and adjust ISS increments to tune front to rear balance. Make small changes and test on your usual surface to find the best compromise between turn-in and mid-corner grip.
