Compatible with Tamiya DT-Series: Aluminum Gear Box (Blue) - JR-THNE06-LB by Jazrider  [JR-THNE06-LB]

Tamiya DT-series Metal Gear Housing Overview

The JR-THNE06-LB aluminum gear box is an aftermarket part engineered for Tamiya DT02, DT03, DT04 and Hornet EVO RC chassis. Produced from CNC-machined aluminum with a blue anodised finish, it replaces the standard plastic housing to provide a more rigid mounting surface for spur and pinion gears and greater resistance to wear during upgraded use.

Installation guidance: this product is intended as a direct replacement for the specified Tamiya platforms, matching original mounting points and bearing positions so motor and gear alignment remain unchanged. When installing, check gear teeth and bearing fit before final assembly. Apply a small amount of thread-lock on metal-to-metal fasteners if they interface with shared chassis threads.

Why fit it: using a metal gearbox reduces flex where the spur mounts, improving gear mesh stability under increased torque from high-power motors or altered gearing. The aluminum case also aids thermal dissipation compared with plastic alternatives, which can benefit longer sessions.

Recommended for model builders and competitors looking for a tough, direct-fit gearbox that improves chassis rigidity and gear reliability on Tamiya DT platforms.
