Designed to maximize the performance of high-horsepower engines Manufactured from specially formulated high-temperature polymer compound and designed with deeper cogs on top and rounded cogs on the bottom Faster and more consistent throttle response, higher speeds and quicker throttle response at mid-speed acceleration Greater secondary acceleration at high rpm and as primary acceleration increases Reduction in slippage during the highest levels of torque Tested and proven to be reliable at well over 12,000 rpm Operates at a cooler running temperature Offers better performance during deceleration (more responsive engine braking) Provides more power to track.
