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

Lightweight drivetrain upgrade for TT01

This GPM titanium dog bone is an RC-scale drivetrain replacement part intended for Tamiya TT01 chassis, specified at 30mm length. It serves as a direct drivetrain link between outdrives and axles where original parts wear or for hobbyist tuning to change drivetrain feel.

Made from titanium, the dog bone emphasizes corrosion resistance and surface hardness compared with common steel or plated parts, while remaining appropriate for model-scale loads. Its role is to provide a stable rotating connection that resists wear under typical club track and practice use.

Installation is straightforward on stock TT01 drivetrains that accept 30mm dog bones, check axle and cup fitment before final assembly. Routine maintenance includes inspecting mating cups for wear and keeping pivot interfaces clean and lightly lubricated with RC-appropriate grease to preserve life and reduce noise.

For tuning, replacing polymer or worn steel dog bones with a titanium unit can slightly change drivetrain feedback and longevity; expect modest changes in feel rather than dramatic performance jumps, and always verify mesh and clearance after installation.

This part is best used as a durable replacement or incremental upgrade on TT01 model cars where builders seek reduced wear and consistent drivetrain behaviour without altering core drivetrain geometry.
