This forward and reverse gear box transmission kit is designed for shaft-driven off-road vehicles powered by 110cc to 150cc horizontal engines. It provides a complete drivetrain solution, allowing smooth switching between forward and reverse operation.
The kit includes a transmission gear box, a 16.7 inch (425mm) drive shaft, and a differential case assembly. Together, these components ensure efficient torque transfer and stable drivetrain performance across various terrains.
Built with hardened gears and a reinforced housing, this unit is engineered for durability and long-term use in demanding off-road environments. The precision-machined 6-spline input shaft and 20mm output shaft help maintain secure connection and reliable power delivery.
This system is widely compatible with many ATV, go-kart, buggy, quad, and utility vehicle builds using 110cc–150cc horizontal engines. It is ideal for replacement, upgrade, or DIY custom projects.
