TAMIYA DT-03 Rear Dogbone 6061-T6 Aluminium DT3158A by GPM  [DT3158A]

Durable Rear Dogbone for DT-03

This rear dogbone is a robust replacement part made to connect the CVD output to the wheel hub on TAMIYA DT-03 drivetrains. It is intended to overcome the common failure point of stock plastic posts and offer more dependable torque transfer.

Made from solid 6061-T6 aluminium with a polished finish, the upgrade is built thicker than the original moulded posts to resist bending and breakage. The axle shaft measures 10mm in diameter, 1mm larger than the factory plastic pieces, and the kit contains 2 pieces for both rear posts.

Installation is a direct swap for DT-03 rear assemblies; check fitment and rotation clearance during trial assembly to avoid binding. Upgrading to thicker aluminium posts reduces rear link flex and helps maintain drivetrain consistency during aggressive throttle or when running heavier setups. Multiple colour finishes are offered by the supplier to match your rig.
