This aluminium front gear box is produced to fit Tamiya Hotshot, Super Hotshot, Boomerang and Bigwig chassis and is identified as model JR-THS12-LB. The blue-anodized housing replaces the plastic case to offer improved stiffness while keeping factory mounting points intact.
Installation is intended for hobbyists familiar with Hotshot-series maintenance and uses the existing screw and alignment locations. During installation verify gear mesh and bearing seating, and normally reuse the existing internal drive components unless you plan an internal upgrade. The housing aims to stabilise front gear alignment and reduce flex under heavy loads, helping preserve consistent front drivetrain operation.
This JR-THS12-LB aluminium front gear box provides a practical upgrade path for Hotshot-series cars, improving front drivetrain rigidity while preserving the original mounting layout and gear geometry.
