The XRAY 364115 shaft, made from premium HUDY Spring Steel, is engineered to sharpen the behaviour of your multi-adjustable slipper clutch. Its narrower profile reduces rotating mass while a hardened, dark finish raises wear resistance, making it a practical upgrade for XRAY XB4 2020 and 2021 setups.
A straightforward modification for racers and hobbyists aiming for crisper clutch feel and longer service life.
