The Exotek Slash 2WD Drag HD Steel CVD Axle Set is a heavy duty hardened steel CVD upgrade kit for the Traxxas Drag Slash, Bandit and Traxxas Slash based conversions that use the narrow Bandit arm setup. Reduced parts count and all steel construction insures reliable racing without fear of deforming or popping out the stock plastic axle sets. The included differential cups use set screws instead of the straight pin to remove slop and reduce vibrations. Requires blue thread lock and cvd oil or grease for installation.
