Tamiya TT02/TT02B Alloy Middle Shaft Joint by GPM TT2B315  [TT2B315]

Alloy middle shaft joint for TT02/TT02B

This alloy middle shaft joint is an aftermarket replacement part produced by GPM for use with Tamiya TT02 series chassis. It is intended as an RC-scale drivetrain component to replace a worn or damaged middle joint, helping to restore alignment and reduce play in the transmission path.

The part is described as an alloy piece; installers should treat it as a standard drivetrain replacement: remove the centre driveshaft section on the TT02/TT02B chassis, inspect adjacent ball bearings and splines for wear, fit the joint with correct orientation, and secure fasteners to factory torque recommendations. No specialised tools beyond common hobby tools are implied.

In tuning context this joint serves a maintenance and incremental-performance role rather than a major performance upgrade, its main purpose being to maintain consistent drivetrain geometry during practice or race preparation on TT02 platforms.
