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

TT01 drivetrain link with titanium durability

The TTT130 titanium dog bone from GPM is made as a direct replacement for Tamiya TT01 drivetrains that use 30mm dog bones. It connects the outdrives to axle cups and is suitable where original parts are worn or when builders want a firmer drivetrain feel.

Fabricated in titanium, this dog bone offers enhanced corrosion resistance and surface hardness compared with plain steel or polymer alternatives, while still coping with typical model running loads. It aims to reduce wear at the rotating joint during regular track or practice sessions.

Installation takes place on TT01 setups that accept 30mm dog bones; always check cup and axle fitment before tightening. Regular maintenance is straightforward: inspect cups for wear, clean pivot surfaces, and apply a small amount of RC-compatible grease to preserve smooth operation and lower noise.

For tuning, replacing flexible or worn components with a titanium dog bone can change drivetrain feedback and extend service intervals; this should be viewed as a subtle performance refinement, not a handling overhaul.

A practical upgrade for TT01 owners looking to lower wear and maintain consistent drivetrain behaviour without changing geometry.
