XRAY 302771 - X4 Precision Aluminum Lower Bulkhead Front L / Rear R  [XR-302771]

XRAY 302771 - X4 Lower Bulkhead for Strength and Accuracy

The XRAY 302771 - X4 Aluminum Lower Bulkhead is a purpose-built part for racers and hobbyists who demand consistent chassis geometry and dependable on-track behaviour. Its design focuses on reliable fitment and predictable steering response.

Centering Pins and Low Anti-Roll Bar Mount

Built with centering pins to make assembly straightforward, this bulkhead keeps geometry consistent across pit setups. The very low anti-roll bar mounting point positions the anti-roll bar wire beneath the drive shafts, lowering the centre of gravity to aid mid-corner grip and balance.

Swiss 7075 T6 Construction and Black Anodized Finish

Manufactured from Swiss 7075 T6 aluminum, the part combines light weight with high strength. The black anodized surface resists wear while adding a clean look. Precision 1mm milled grooves for ball bearing hubs shift the bulkheads 1mm closer to the chassis centre line on each side, helping to fine tune balance and tyre load.

Exact Fit for Front Left and Rear Right

This bulkhead is engineered specifically for the XRAY X4 chassis and fits the front left and rear right locations as a direct replacement or performance upgrade. The machining and tolerances ensure smooth integration with standard X4 components.
