Rear Traction Upgrade for Asphalt Racing

The XRAY 303722-O Aluminium Rear Lower 1-piece Suspension Holder is crafted for the rear bulkhead area of XRAY T4 cars. It is optimised to boost traction on asphalt surfaces where grip is typically low to medium. Installing this holder helps deliver a steadier rear end and tighter, more controlled corner exits.

Fitment Notes and Setup Tips

This holder is intended to be used alongside the right aluminium holder #303716-O and left aluminium holder #303717-O. It is ideal for drivers who want to fine-tune rear geometry for specific asphalt track conditions, enabling precise setup adjustments.

Material and Machining

Produced from Swiss 7075 T6 aluminium and CNC machined, this component balances strength with reduced weight. The material choice gives durability for race use while keeping mass low to preserve agility.
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 this fit my XRAY T4 without modifications?

Yes, the holder is designed for XRAY T4 rear bulkheads and fits as intended when paired with the specified left and right aluminium holders. Minor setup tweaks may be needed depending on your chassis layout.

How does the 1-piece lower holder affect handling?

By changing lower rear mount stiffness and geometry, the part improves rear stability on low-to-medium grip asphalt and smooths throttle inputs through corners.

Is Swiss 7075 T6 a good choice for durability?

Swiss 7075 T6 aluminium offers a strong strength-to-weight ratio common in high-performance RC parts, providing reliable rigidity while keeping weight down.
