The TT02-13117-RD universal swing shaft set is an aftermarket component intended for direct installation on Tamiya TT-02 chassis. Made from aluminum and finished in red, the shafts are designed to stabilise the swing shaft connection and support drivetrain alignment under everyday hobby conditions.
Replacing the stock swing shafts, this set functions as a tuning or replacement item to reduce looseness in the universal joint area and promote smoother transfer of torque from the gearbox to the wheels during acceleration and cornering. It is not a structural modification to the chassis.
Installation follows standard TT-02 service practices: remove affected drive parts, check the new shafts against the originals for correct engagement and length, install, and confirm free rotation and suspension clearance. Use light spline grease at metal-to-metal contact points and re-evaluate after a short test run.
Use alongside routine servicing such as fresh grease, inspected bearings, and correct differential setup for optimal results. Intended for RC model use only and not for use in real vehicles.
