Drive Belt for # 6500 & 6502

The Drive Belt for #6500 & #6502 is a critical serpentine belt designed to synchronize accessory drive operation on high-performance and racing engine builds. As an experienced mechanic knows, the belt routing and tension directly affect alternator charge rate, water pump circulation, and power steering responsiveness—making belt selection non-negotiable for reliable startup and consistent performance. This OEM-specification belt is engineered for both COMP CAMS #6500 and #6502 crate engines and compatible platform builds, delivering the precise fit and durability required in demanding automotive applications.

Manufactured to strict tolerances, the Drive Belt for #6500 & #6502 features consistent ribbing geometry and elastomer compound formulation that resists glazing, cracking, and premature wear under thermal stress. The belt's compact profile (12.1 inches in length, 6.4 inches width reference) integrates seamlessly into the factory pulley arrangement, ensuring proper wrap angle and belt deflection for maximum power transfer without slippage. Quality construction minimizes noise and vibration transmission to the engine block, critical factors when tuning ignition timing and validating baseline horsepower during dyno testing.

Builders and restorers working with COMP CAMS turnkey engines will appreciate the direct fitment of this belt specification—eliminating guesswork during final assembly and reducing potential downtime from incompatible routing. Whether you're completing a crate engine swap, rebuilding a vintage small-block platform, or maintaining a high-mileage performance build, proper belt selection ensures alternator output stabilizes electrical systems under load, protecting fuel injectors and ignition modules. Inspect and replace every 60,000 miles or upon visual signs of fraying, cracks, or hardening; preventive replacement during major service avoids roadside failure.
