The XRAY 365444 central dogbone shaft universal joint offers a heavy duty central driveline upgrade for XB4 chassis. Built from HUDY Spring Steel, it helps reduce routine servicing while maintaining reliable performance in both front and rear positions.
HUDY Spring Steel provides strong fatigue resistance and consistent material behaviour under load, which lowers the chance of unexpected failure. The joint is precision made to work with XB4 2021 Carpet and Dirt Specs so the car responds predictably across track types.
Specifically tailored for the XRAY XB4 series, this central dogbone joint fits carpet and dirt variants and can be installed quickly using standard hobby tools to minimise pit time between runs.
