PULLEY BB CHEV A/C ADD-O

The PULLEY BB CHEV A/C ADD-O from TRANS-DAPT is a single-groove crankshaft pulley engineered for big block Chevy engine builds requiring air conditioning integration. This add-on pulley serves hot rodders, restomod builders, and serious engine shops who need to retrofit modern A/C systems onto classic or modified big block platforms without sacrificing OEM-style appearance or reliability. Whether you're upgrading a vintage muscle car or building a street engine, this pulley bridges the gap between traditional serpentine accessory drives and contemporary climate control demands.

Manufactured from durable steel and finished in polished chrome, the PULLEY BB CHEV A/C ADD-O features a 6.8-inch diameter and is specifically designed for short water pump configurations common in compact engine compartments. The single-groove V-belt profile ensures compatibility with standard belt routing while maintaining proper tension and load distribution across the air conditioning compressor and other driven accessories. The chrome finish not only delivers a professional, show-quality appearance but also provides corrosion resistance critical for long-term underhood durability in high-heat, high-humidity engine environments.

Installers working with big block Chevy engines—particularly those running short water pump setups in tight bays—will find this pulley indispensable for A/C retrofit applications where OEM pulleys lack A/C provisions. Weighing just 1.87 lbs, it minimizes rotating mass without compromising strength, making it suitable for both street and performance applications. Proper belt routing and tension adjustment during installation ensure optimal compressor engagement and extended belt life across all engine speeds.
