42mm TRF/TT-02 Swing Shaft, RC spare part

The TRF/TT-02 42mm Swing Shaft (Hard) is a drivetrain upgrade part for RC chassis builds that need efficient power transfer through an assembly type universal shaft. Each pack contains 2 silver metal shafts marked A 42, with a reinforced construction and a hard anodized finish that supports repeated use in running setups where the driveline is under regular load. A key detail lies in the shaft geometry: the drive pin and cross shaft are positioned 90 degrees apart, a layout that promotes smoother rotation when power is applied. That mechanical relationship helps the universal shaft work with less interruption through the turn of the drivetrain, which is especially useful when a chassis is set up with stronger power systems. The different thickness compared with standard counterparts gives these parts a more reinforced specification for replacement, maintenance, or tuning work. The 42 mm size is intended for direct use with TT-02 Type-S and TB Evo.6 chassis cars, making the pair a focused option for keeping those platforms running cleanly. In workshop use, the shafts suit routine rebuilds, worn-part replacement, or a driveline refresh before the next session on track. The 2-piece pack also provides the matching pair needed for balanced installation within the compatible universal shaft setup.
