TAMIYA Hotshot / Super Hotshot / Boomerang / Bigwig Aluminum Front Gear Box by JAZRIDER JR-THS12-LB  [JR-THS12-LB]

Aluminum front gearbox for Tamiya chassis

This aluminum front gear box is a direct-fit replacement intended for Tamiya Hotshot, Super Hotshot, Boomerang and Bigwig chassis, provided by JAZRIDER as model JR-THS12-LB. It is supplied in blue anodized appearance and serves as a sturdier alternative to the original plastic housing, intended for those who want a more rigid front drivetrain assembly while maintaining stock mounting points.

Installation is straightforward for hobby technicians familiar with Tamiya Hotshot family maintenance, using existing screws and alignment points. During installation check gear mesh and bearing seating, and reuse original drive components unless an upgrade is specified. The part's role in tuning is to stabilize front gear alignment, reduce flex under load, and provide a consistent mounting surface for spur and pinion arrangements on the front drivetrain.

For hobbyists maintaining or tuning Tamiya Hotshot series cars, this JAZRIDER aluminum front gear box offers a practical upgrade path to improve front drivetrain rigidity and long-term serviceability while keeping original mounting layout and gear geometry.
