Cloyes B10245 Product Description
Cloyes pulleys are engineered for smooth, reliable belt operation in even the toughest conditions. Designed with OE-level precision, high-durability materials, and advanced corrosion resistance, they help maintain optimal belt alignment, minimize vibrations, and extend the life of the entire system. Built to meet or exceed OE specifications, Cloyes pulleys ensure a perfect fit and long-lasting performance you can trust. Pro Tip: Belt drive system components wear out at the same rate. For optimal performance and fewer comebacks, inspect pulleys at 60,000 miles and replace them—along with belts, tensioners, and other components—at 90,000 miles. Industry-leading warranty & support and dedicated technical support to ensure hassle-free installation and performance.
