40 Series Torque Converter Kit for 8-16HP Go Karts

Upgrade your go-kart, ATV, or mini bike with this 40 Series Torque Converter Kit from TouSuaRSi, designed for engines between 8-16HP. This kit features asymmetric drive and driven pulleys that reduce engine strain while optimizing torque delivery, resulting in greater low-speed power and smoother acceleration. The kit includes a 5.3in driver pulley, an 8.1in driven pulley, and a high-quality belt (0.8in x 0.4in) for reliable performance.

Built with wear-resistant iron and aluminum, the pulleys ensure durability and efficient heat dissipation, while built-in overload protection and ventilation holes enhance safety during rugged use. The torque converter engages at 2350±200rpm, making it ideal for off-road adventures. Suitable for 10T (#40/41 420 chain) or 12T (#35 chain) sprockets (chain sold separately), this kit is a must-have for performance-driven riders.
