Constructed with specially formulated, high temperature polychloroprene. Aramid fiber reinforcement construction increases horsepower capacity and more responsive engine braking during deceleration. Tested and proven reliable at over 12,000 rpms, for faster, more consistent throttle response and improved durability. Features deeper cogs on top and rounded cogs on bottom for ultimate flexibility, longer belt life and cooler running temperatures compared to leading competitors. Quicker throttle response at mid-speed acceleration. Greater secondary acceleration at high RPM. Reduction in slippage during the highest levels of torque. Increased horsepower capacity. Better performance during deceleration (more responsive engine braking). Cooler running than the leading competitors. 1-Year Warranty.
