Why it helps
Smaller, more powerful drivetrains run higher drum speeds, more horsepower, higher loads and higher energy absorption. That energy becomes heat, which can degrade and destroy transmissions.
The Pro-Series band is made of Kevlar fibers with solids and resins. It resists heat up to 700°F, gives higher holding capacity and more durability, and stays stable in high-energy conditions. The Kevlar fiber blend has a higher friction coefficient, and the anchors are heat-treated for mechanical strength.
Notes
They require higher drum speeds, more horsepower, increased loading and higher energy absorption.
