XRAY 303711-O Aluminum Rear Lower Suspension Holder T4 Off-Road to On-Road  [XR-303711-O]

Stiffen your T4 rear end with a precision suspension holder

The XRAY 303711-O Aluminum Rear Lower Suspension Holder fits at the front of the rear bulkhead on T4 models and is CNC machined from Swiss 7075 T6 aluminum. The component gives a stiff, precise mount that helps preserve suspension geometry under load while keeping weight low.

Designed around high grip performance

Made for high-traction tracks, this holder increases rotation and sharpens steering response. That improvement in rotation may slightly lower rear traction, so it is best matched with setups that favour agility. The part includes suspension adjustment features inspired by XRAY's XB8, adapted for 1/10 on-road use.

Long-lasting CNC build for reliable geometry

The CNC-cut 7075 T6 aluminum construction offers a lightweight yet resilient solution that resists bending after impacts. The mounting allows free movement of suspension arms, aiding traction and producing smoother cornering behaviour.
