TAMIYA Hotshot Rear Gear Box Housing - JR-THS13-LB Upgrade for Hotshot/Super Hotshot/Boomerang/Bigwig by Jazrider  [JR-THS13-LB]

Blue anodized aluminum rear gear housing for TAMIYA Hotshot

The JR-THS13-LB aluminum rear gear box is a direct-fit upgrade that swaps the original stamped plastic housing for a precision-machined aluminum unit finished in blue anodize. The metal housing gives a more rigid mount for internal gears and bearings compared with the stock piece.

Use case and installation: positioned as the rear gearbox housing, this component maintains the spur and pinion alignment inside the rear chassis section. It is suitable for builders seeking a tougher housing to limit drivetrain flex during heavier loads or tuning trials.

Fitment notes: the housing follows the original mounting layout and bolt pattern used by the listed TAMIYA models for straightforward installation. The removable cover points remain the same so routine access to gears and bearings is preserved.

For RC enthusiasts wanting a firmer rear gearbox mounting on vintage TAMIYA Hotshot designs, this aluminum housing offers a simple metal replacement while retaining original geometry.
