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

TT01/TT02 universal swing shaft upgrade

The TTT2233 universal swing shaft is an aftermarket RC-scale replacement made for Tamiya TT01 and TT02 chassis. It pairs titanium contact surfaces with Alloy-7075 construction and ships as a 1pr set with shim washers to help fine-tune endplay and driveline alignment. This description concentrates on fit, installation advice, and the part's role in chassis tuning rather than promotional claims.

Compatibility: designed to fit the universal drive locations used on TT01 and TT02 platforms. Installation commonly reuses stock retaining hardware and requires basic removal of the front or rear differential assemblies to swap the original swing shafts. Inspect bulkhead clearances and drive cup seating during fitting to avoid binding or unwanted contact.

Tuning role: replacing stock swing shafts with a mixed titanium and 7075 alloy assembly aims to reduce wear at high-stress contact points while keeping rotating mass reasonable. The included shims permit small positional adjustments to limit lateral play. In everyday running this part can extend service life around the swing joint and provide a firmer driveline feel compared with softer original shafts.

For hobbyists changing out worn swing shafts or seeking a tighter driveline response on TT01 and TT02 chassis, the TTT2233 set offers a direct aftermarket replacement with shims for straightforward alignment tweaks.
