High Precision Lower Suspension Holder for T4 Racing

The XRAY 303713-O Aluminum Lower Suspension Holder is a CNC machined upgrade made from Swiss 7075 T6 aluminum to reinforce the left lower mount on XRAY T4 series cars. Built for repeatable performance, it delivers the strength needed for frequent track use without compromising setup consistency.

Compatibility and Tuning Options

This left-side holder fits standard rear suspension layouts and is ARS compatible, offering extra roll center positions so racers can dial in handling for different track surfaces. The geometry supports fine adjustments to rear roll and balance for tighter cornering and improved stability.

Benefits of Swiss 7075 T6 Aluminum

Swiss 7075 T6 aluminum provides an excellent strength-to-weight ratio, making it ideal for high stress suspension parts. Using this alloy in the XRAY 303713-O gives a reliable, stiff mounting point that stands up to racing loads while keeping mass to a minimum.
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 chassis?

It is designed for the XRAY T4 series left lower suspension position and works with standard and ARS setups; verify your chassis uses the same mount layout before ordering.

Is installation difficult for club racers?

Installation is a direct swap with common hand tools; we recommend using thread locker on steel hardware and checking alignment after fitting.

Will this change handling or weight distribution?

The part adds minimal mass while increasing stiffness, which can alter roll response; expect subtle changes that are best tuned with shock and sway bar adjustments.
