XRAY 303711-O Aluminum Rear Lower Suspension Holder T4 Race Fit  [XR-303711-O]

Precision rear lower suspension holder for the T4 chassis

The XRAY 303711-O Aluminum Rear Lower Suspension Holder is a carefully machined component made to sit at the front of the rear bulkhead on the T4 series. Constructed from Swiss 7075 T6 aluminum, this holder delivers a strong, accurate mounting point that helps the car retain geometry under load while keeping weight down.

Set up for high grip circuits

Built with high-traction tracks in mind, this part increases the car's rotation and tightens steering feel. That added rotation can slightly reduce rear traction, so it works best for drivers chasing sharper turn-in and quicker corner transitions. The part incorporates suspension adjustment options originally seen on XRAY XB8 models, now adapted for 1/10 on-road tuning.

Rugged CNC construction and consistent geometry

Made by CNC from Swiss 7075 T6 aluminum, the suspension holder gives a lightweight yet durable support for the T4 platform. The design resists deformation after hard impacts and lets the suspension arms move freely in their mounting points to sustain traction and smoother cornering behaviour.
