Drive Belt Designed to maximize the performance of high-horsepower engines, Manufactured from specially formulated to high-temperature polymer and designed with deeper cogs on top and rounded cogs on the bottom, Faster and more consistent throttle response, higher speed and quicker throttle response at mid-speed acceleration, Greater secondary acceleration at high RPMs and as primary acceleration increases, Tested and proven to be reliable at well over 12,000 RPM, Operate at a cooler running temperature, better performance during deceleration (more responsive engine braking), Provide more power to track
