Tamiya TT01 Aftermarket Titanium Dog Bone 30mm TTT130 by GPM  [TTT130]

Titanium replacement dog bone for TT01 drivetrains

The GPM TTT130 titanium dog bone is an aftermarket drivetrain link for Tamiya TT01 chassis that require 30mm dog bones. It serves as the rotating connection between outdrives and axle cups and is intended for replacements or light tuning changes.

Titanium gives the component better resistance to corrosion and wear than many steel or plastic alternatives, while still matching the load expectations of model-scale use. The design helps maintain a smooth rotating joint during club sessions and everyday running.

Installation is quick on TT01 assemblies that accept 30mm dog bones; verify cup and axle sizing before tightening fixings. For maintenance, check mating cups regularly, keep pivot faces clean, and use a small amount of recommended RC grease to limit wear and noise.

When used as a tuning upgrade, moving from polymer or worn steel dog bones to titanium can change drivetrain feel and longevity slightly; treat this as a refinement rather than a major performance upgrade, and always recheck clearances after fitting.

Ideal as a robust spare or incremental upgrade on TT01 cars where longevity and consistent drive feel are priorities.
