The XRAY 361190 Rear Graphite Chassis Brace Deck is built to reduce unwanted rear flex and stabilise handling under load. Fabricated from 2mm high-grade graphite, the brace nests into the lower section of the rear composite brace and connects directly to the chassis, creating a firmer rear platform for the XB4 series.
The 2mm graphite plate offers a good balance between stiffness and mass, helping to maintain throttle response while strengthening the rear structure. This makes it a sensible choice for racers who want a dependable upgrade without a heavy penalty.
Designed specifically for the XRAY XB4 2021 Carpet and Dirt Specs, the part installs cleanly into stock layouts. Use it as a replacement or a tuning component to fine tune rear behaviour on both carpet and dirt tracks.
