GTC Torque Converters Precision Made High Quality means Top Performance and Durability from GTC
Torque Converters dramatically improve Take Off Power, Acceleration, Climbing Ability and Top End Speed on Gokarts, Minibikes and other Small Vehicles. Vehicles currently using a Centrifugal Clutch can easily upgrade to a TC2 Torque Converter
Bench Test Video
Back in 1998, Gokarts USA's initial testing of the GTC Torque Converter proved highly successful. The TC2 was road tested on a Little Bad Ass Minichopper with a 5hp Tecumseh Engine. The TC2 model 1002 was used which has a 3/4" Bore and #40/41P Chain. The performance impressed our technicians. The low end power and torque was strong enough to raise the front wheel with just barely applying the throttle. Take off and acceleration was also remarkably impressive. Taking on a steep hill from a complete stop, the TC2 smoothly down shifted and pulled the 200-pound rider up the hill with ease. On level ground, at maximum throttle, the TC2 shifted into a very high overdrive ratio and gave us an impressive top speed of 52mph from this stock 5hp Tecumseh. All in all, the TC2 performed significantly better than the stock TAV2 the bike originally came with  
The TC2 Torque Converter is a complete kit that includes both drive and driven clutches, belt, billet aluminum engine mounting plate with a built-in jackshaft and sprocket, all hardware and installation instructions

High Performance
The TC2 is a High-Performance asymmetrical torque converter system in which the sheave faces have different angles. The system operates with the torque sensing cam in an outboard position allowing for in-line operation of the unit. The primary benefit of this design is that it allows proper alignment of the final drive chain to be on the same side of the vehicle as the torque converter. Moreover, the angle on the movable sheave being set at 18 degrees enables the unit to raise the belt to a larger pitch diameter with less travel of the sheave. This allows the unit to achieve higher overdrive ratios at maximum RPM

·         In-Line Operation

·         Powerful Low Ratio

·         Smooth Shifting on Load Demand

·         Infinite High / Low Ratios

·         High Performance Overdrive


The TC2 provides Neutral engagement at Engine Idle. At 2200 RPM, the system engages for a Powerful Low Ratio for great takeoff speed. At Mid Range, the TC2 instantaneously shifts ratios based upon RPM and Load Requirements. Finally, the High-Performance Overdrive engages for maximum speed
