TAMIYA Tractor Trucks Precision Universal Drive Shaft 92-128mm TTT-92128-BK by Jazrider  [TTT-92128-BK]

Universal prop shaft, adjustable

This universal drive shaft is intended for TAMIYA Tractor Trucks, supplied in black steel and adjustable between 92 and 128mm. It is aimed at builders seeking a metal replacement or upgrade to span gearbox output and axle input on tractor-truck RC models.

To fit, verify the centre-to-centre distance of your couplers lies within the 92-128mm window, match splines or couplers and slide the shaft into position. After securing, confirm concentricity and check endplay by hand before running the model to avoid drivetrain binding. This assumes compatible couplers and driveline hardware are already present.

Using an adjustable shaft makes it easier to fine-tune driveline alignment after chassis changes or suspension travel variations, reducing visible slack. The steel material offers improved wear resistance and dimensional stability over plastic alternatives, beneficial for longevity and consistent driveline performance.
