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

Durable titanium dog bone for TT01 use

This titanium dog bone from GPM is an RC-scale drivetrain replacement for Tamiya TT01 chassis, sized at 30mm to replace worn or soft originals. It links outdrives to axle cups and is aimed at hobbyists tuning drivetrain feel or restoring dependable rotation.

With titanium construction the part improves resistance to corrosion and surface wear compared with common steel or polymer pieces, while remaining appropriate for model-scale loads. It provides a stable rotating connection suited to club track sessions and regular practice.

Fitment is straightforward on stock TT01 drivetrains that accept 30mm dog bones; confirm axle and cup dimensions before final assembly. Routine upkeep should include inspecting mating cups for wear and keeping pivot areas clean and lightly lubricated with RC-appropriate grease to reduce noise and extend service life.

As a tuning step, swapping polymer or worn steel dog bones for this titanium unit can subtly alter drivetrain feedback and durability; expect incremental changes rather than major handling shifts, and always verify mesh and clearance after installation.

Best used as a long-lasting replacement or modest upgrade on TT01 vehicles where builders want reduced wear while keeping original drivetrain geometry intact.
