Heavy-Duty Drive Power: The Detroit Diesel OEM AC Belt Advantage

Measuring 105.94 inches in effective length with a precision-molded 8-rib profile, it provides superior surface contact that virtually eliminates slippage and "belt squeal" when your AC compressor kicks on under heavy loads.

This advanced material is specifically formulated to resist the extreme under-hood temperatures, oil exposure, and continuous flexing that causes cheap aftermarket belts to crack and snap.
