The JAZRIDER JR-THS13-BK black aluminium rear gear box is engineered as a straightforward replacement for the stock plastic housing on Tamiya Hotshot, Super Hotshot, Boomerang and Bigwig. It focuses on durability and everyday usability for hobbyists who want a low fuss upgrade.
Made from machined aluminium, the JR-THS13-BK increases resistance to impact and wear while keeping serviceability in mind. The housing preserves standard bearing seats and gear locations so original components can usually be reused.
Fitment follows the original mounting points and requires only standard RC hand tools. Check gear mesh, bearings and seals during installation and re-use existing fasteners where possible for a reliable fit.
