Tamiya TL01 38mm Universal Swing Shaft Set TL1238S by GPM  [TL1238S]

Durable TL01 swing shaft upgrade

A hard steel universal swing shaft set measuring 38mm, produced as model TL1238S for use with the Tamiya TL01 chassis. The steel shafts replace stock swing shafts to reduce play and slow the onset of wear without modifying chassis geometry.

The kit is supplied as a matched pair for straightforward replacement where TL01 swing shafts are used. Fitting usually involves removing hubs and drive cups, swapping the shafts, and checking for clearance through full suspension travel and steering movement. Secure fasteners to TL01 recommended torque and verify that your existing drive cups and universals are compatible before final assembly.

In practical tuning terms, switching to hard steel increases driveline stiffness and improves wear resistance, producing a sharper transfer of power with a modest weight increase versus lighter alloys. This makes the set useful for drivers who want durability and less driveline lash during repeated sessions.

Fit these 38mm hard steel shafts when you need a simple steel upgrade for TL01 swing shafts and always confirm drive cup fitment prior to running.
