TAMIYA Hotshot Compatible Front Gear Box Aluminum Upgrade JR-THS12-LB by Jazrider  [JR-THS12-LB]

Sturdy aluminum front gearbox tailored to Tamiya Hotshot platforms

This precision-machined aluminum front gear box is intended to replace the factory plastic housing on Tamiya Hotshot, Super Hotshot, Boomerang and Bigwig cars and is offered as model JR-THS12-LB. The blue-anodized case adds rigidity and resists wear better than the original plastic while preserving stock mounting points.

Installation suits hobbyists experienced with Hotshot-series maintenance; the part uses the existing screw pattern and alignment features. During the fitment process, inspect gear mesh and bearing positions, and normally retain your original internal components unless performing a full drivetrain upgrade. The strengthened housing helps keep front gears aligned and reduces flex under load for more consistent operation.

For enthusiasts working on Hotshot-family rigs, the JR-THS12-LB aluminum housing provides a reliable upgrade to reduce drivetrain play and improve long-term serviceability without changing gear geometry.
