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

Stiffer driveline for TL01

A hard steel 38mm universal swing shaft set designed for the Tamiya TL01 chassis, model TL1238S. These shafts replace the stock items to address play and wear while keeping the original chassis geometry intact.

The pair is supplied ready for direct replacement in TL01 applications. Typical fitting involves removing wheel hubs and drive cups, swapping in the 38mm shafts, and checking clearances through suspension movement and steering angles. Tighten fasteners to TL01 torque settings and ensure compatibility with your existing drive cups and universals before finishing assembly.

In setup terms, steel shafts alter driveline stiffness and wear patterns, offering firmer power delivery at the cost of slight added weight compared to lighter alloys. They suit drivers who prioritise durability and less axial play during repeated practice or club runs.

Use these 38mm hard steel shafts as a straightforward durability upgrade for TL01 swing shafts and confirm fitment with your drive cups prior to use.
