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

Adjustable universal drive shaft

This is an RC-scale universal drive shaft designed for Tamiya Tractor Trucks, finished in black steel and adjustable across a 92 to 128mm span. The component is intended as a direct replacement or upgrade in model tractor-truck drivetrains where a steel, adjustable-length shaft is required to bridge the distance between gearbox output and rear axle input.

Installation is practical and mechanical: verify the measured centre-to-centre distance of the couplers on your model within the 92 to 128mm range, align the splines or couplers, and slide the shaft into position. Final fitment should be checked for concentricity and endplay before running the model to avoid binding in the drivetrain. This description assumes use with appropriate RC-scale couplers and driveline hardware already present on the model.

For tuning, adjustable length lets builders fine-tune driveline alignment and reduce visible slack where chassis modifications or suspension travel change the effective shaft span. As a steel part, it prioritises durability and dimensional stability compared with common plastic alternatives, making it suitable where metal shafts are preferred for longevity and straight-line driveline behaviour.
