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

Aftermarket universal swing shaft for TT01/TT02

The TTT2233 universal swing shaft is an aftermarket RC-scale replacement intended for Tamiya TT01 and TT02 chassis. It combines titanium contact areas with Alloy-7075 sections and is supplied as a 1pr set with shim spacers to help set endplay and driveline alignment. This overview highlights fitment, installation considerations and the component's role in chassis setup rather than promotional language.

Compatibility: made for the universal drive mounting points used on TT01 and TT02. Installation typically reuses the stock retaining parts and requires removal of either the front or rear differential to swap the shafts. Check for adequate clearance around bulkheads and the drive cups when fitting to prevent rubbing or binding.

Tuning role: using titanium at the joint surfaces with 7075 alloy elsewhere aims to improve wear characteristics where it matters while keeping rotating mass controlled. The included shims permit small positional corrections to reduce side-play. In real world use the part can increase service life in the swing joint area and produce a firmer driveline feel relative to softer factory shafts.

For modelers replacing worn swing shafts or dialing in driveline stiffness on TT01/TT02 cars, the TTT2233 set provides a direct aftermarket choice complete with shims for simple alignment tweaks.
