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

Technical overview

The TTT130 titanium dog bone from GPM is engineered as a precision aftermarket drivetrain link for Tamiya TT01 platforms that use 30mm dog bones. It connects outdrives and axle cups with a focus on consistent running and reduced wear under typical model loads.

Manufactured for corrosion resistance and enhanced surface hardness, the titanium construction improves wear life compared to many common steel or polymer options while remaining appropriate for TT01 drivetrain stresses. The part supports consistent rotational behavior and lower long-term maintenance intervals.

Fitment on TT01 assemblies accepting 30mm dog bones is straightforward; verify cup and axle diameters before assembly and check engagement after installation. Routine service should include inspection of mating cups and light lubrication of pivot interfaces with a suitable RC grease to sustain quiet, reliable operation.

Intended as a precision, durable replacement component for TT01 builders seeking predictable drivetrain behaviour and extended service life.
