Tamiya TT01/TT02 Universal Swing Shaft Titanium + Alloy-7075 with Shims by GPM TTT2233  [TTT2233]

Universal swing shaft for TT01/TT02

The GPM TTT2233 universal swing shaft is an aftermarket RC-scale replacement designed for Tamiya TT01 and TT02 chassis. It combines titanium and Alloy-7075 components and ships as a 1pr set with shims to help fine-tune endplay and driveline alignment. This article focuses on fit, installation considerations, and the part’s role in chassis tuning rather than marketing claims.

Compatibility: the component is intended for the TT01 and TT02 platforms, fitting the universal drive locations used on those chassis. Installation typically reuses stock retaining hardware and requires basic disassembly of the front or rear differential assemblies to replace the original swing shafts. Check clearance around bulkheads and drive cups during fitting to avoid binding.

Tuning role: swapping to a mixed titanium and 7075-alloy shaft aims to offer improved wear resistance at high-stress contact points while keeping rotating mass in check, and the included shims allow small positional adjustments to minimise side-to-side play. In practice, this part serves to increase service life of the swing joint area and provide a firmer feel under load when compared with softer stock components.

For hobbyists replacing worn swing shafts or seeking a stiffer driveline response on TT01/TT02 chassis, this GPM TTT2233 set provides a direct aftermarket option that includes shims for straightforward alignment adjustments.
