Tamiya TT-02 Universal Swing Shaft Upgrade - TT02-13117-RD by Jazrider  [TT02-13117-RD]

Aluminum swing shaft upgrade for TT-02 drivetrains

The TT02-13117-RD aluminum universal swing shaft set is an aftermarket drivetrain upgrade designed for direct fit on Tamiya TT-02 chassis. Machined aluminum with a red finish increases shaft stiffness and helps preserve drivetrain geometry under routine hobby loads.

As a replacement for the stock swing shafts, this set reduces play in the universal joint area to deliver smoother torque transfer between the gearbox and the wheels during cornering and hard acceleration. It is a service and tuning component rather than a redesign of the drivetrain.

Installation is simple for anyone experienced with TT-02 maintenance: remove existing drive pieces, check the new shafts against the originals for correct fit, slide into position, and confirm free rotation and clearance through suspension travel. Apply a light spline grease where metal-to-metal contact occurs and validate there is no binding after a short test run.

Use this part as part of a broader tune-up, combined with fresh grease, correctly seated bearings, and an appropriately set differential. Intended for RC model use only and not for any real vehicle application.
