Drive Components

Shop TrailMaster Mid XRX-R drive components, including belt-drive kits, torque-converter pulleys and bushings, drive chains, master links, sprockets, chain adjusters, rear axles, axle bearings and mounting hardware.

Match your reverse-equipped Mid XRX-R, production year and engine version before ordering. Compare belt specifications, chain size, sprocket tooth count, shaft dimensions and bearing numbers with your original parts. Review individual fitment notes rather than assuming every component fits both 6.5hp and 7hp versions.
