The JNDO Super 30 Series Torque Converter Kit is a comprehensive performance upgrade designed for small off-road vehicles. For enthusiasts looking to improve the mechanical efficiency of their ride, this kit replaces traditional clutch systems that struggle under high-demand conditions. By utilizing an asymmetrical design, the system provides a reliable solution for vehicles with larger tires or those navigating challenging terrains that require consistent torque delivery.
Advanced Asymmetrical Drive System
This torque converter operates on an asymmetrical principle where the sheave faces are set at different angles—18° on the movable side and 2 1/2° on the stationary side.This specific geometry allows the belt to reach a larger pitch diameter within the drive clutch during high-RPM operation. Consequently, the system can achieve a 0.90:1 ratio, providing a 10% overdrive that standard symmetrical systems cannot match. This alignment also ensures the drive chain remains on the same side of the vehicle as the P.T.O., simplifying mounting requirements in compact engine bays.
High-RPM Performance And Compatibility
The Super 30 Series Driver is specifically recommended for Stage 2 or higher engines running at 4000+ RPM, such as the 196cc, 212cc, and 225cc small block models. While stock motors at 3600 RPM may not see a performance change, high-RPM applications will experience improved acceleration and better top-end speed. The driver is rated for up to 15HP depending on the specific application, ensuring it can handle the power of modified small engines.
Installation And Component Quality
This kit is a reproduction of the 30 series TAV2 system and includes all components necessary for a full installation. Users receive two distinct sprockets—a 12-tooth sprocket for #35 chain and a 10-tooth sprocket for #41/40/420 chain—to ensure compatibility with various drive setups. The heavy-duty back plate and high-quality belt are engineered for durability and reliable engagement during off-road use. For proper maintenance and safety, it is essential to ensure the jackshaft nut is torqued correctly before use without overtightening, which could damage the internal bearings.
