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

Precision titanium drive link for TT01

The GPM TTT130 is a titanium dog bone designed as a direct replacement for Tamiya TT01 chassis that use 30mm dog bones. It provides the rotating link between outdrives and axle cups, suitable for replacing worn parts or fine-tuning drivetrain response.

Titanium construction improves surface hardness and reduces corrosion compared with standard steel or plastic parts, while still matching the load requirements of scale RC running. The component helps maintain smooth rotation and resist wear during normal club and practice use.

Fitting is simple on TT01 layouts that accept 30mm dog bones; check axle and cup fit before locking components in place. Standard upkeep includes periodic inspection of cups for wear and light lubrication of pivot interfaces with an RC-compatible grease to keep noise down and extend component life.

Using titanium in place of polymer or aging steel dog bones can subtly alter drivetrain feedback and extend service life; this should be considered an incremental durability and refinement upgrade rather than a dramatic performance modifier.

A sensible upgrade for TT01 owners seeking reliable drivetrain performance and lower replacement frequency without altering core geometry.
