Tamiya TL01 38mm Hard Steel Swing Shaft Replacement TL1238S by GPM  [TL1238S]

Reinforced TL01 swing shafts

This 38mm hard steel universal swing shaft set is built for the Tamiya TL01 chassis, model TL1238S. It replaces stock swing shafts with a tougher steel option to help eliminate play and slow wear without changing chassis geometry.

The component ships as a matched pair suitable for direct installation in TL01 setups. Installation normally requires removing wheel hubs and drive cups, fitting the replacement shafts, and confirming there is no interference during full suspension and steering movement. Apply correct TL01 fastener torque and check the fit with your existing drive cups and universal joints before completing the job.

From a tuning perspective, hard steel shafts increase stiffness and durability, producing sharper drivetrain response while adding modest weight compared with lighter materials. They are recommended where robustness and reduced axial backlash are priorities for regular running.

Choose this set for a simple, rugged steel swap on TL01 swing shafts and always verify drive cup compatibility before tightening fasteners.
