DAYCO BELT XTX5045

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 Greater secondary acceleration at high rpm's and as primary acceleration increases Faster and more consistent throttle response, higher speed and quicker throttle response at mid-speed acceleration Tested and proven to be reliable at well over 12,000 rpm Offers better performance during deceleration (more responsive engine braking) Operates at a cooler running temperature Provides more power to track Belt length is measured by OC (Outer Circumference). Belt width is measured by top width.
