BBC LWP 2 Groove Water Pump Pulley Chrome

The BBC LWP 2 Groove Water Pump Pulley Chrome is a precision-engineered cooling system component built for big-block Chevrolet engines running long-water-pump configurations. This chrome-finished pulley replaces the factory unit and serves as a critical interface between your serpentine belt drive system and the water pump shaft. Whether you're building a street engine, restoring a classic muscle car, or upgrading an existing BBC platform, this pulley ensures reliable coolant circulation and maintains proper belt tension across your accessory drive.

Manufactured by Specialty Products Company, this unit features a two-groove design optimized for dual-belt or single-serpentine configurations common in high-performance BBC builds. The chrome plating provides corrosion resistance in harsh underhood environments while delivering the polished appearance demanded by show-quality restorations and custom engine bays. The pulley's 6.75-inch outer diameter and precisely machined bore ensure concentricity with your water pump shaft, reducing vibration and extending serpentine belt life. At just over 2 pounds, it's lightweight enough for racing applications while maintaining the structural integrity needed for continuous-duty street and truck use.

This pulley is essential for anyone converting a BBC to long-water-pump orientation, upgrading from points to serpentine ignition systems, or refreshing aging cooling systems on Chevrolet big-blocks. Compatibility spans generations of BBC applications—from 1965–1995 production engines to modern crate motors—provided your water pump inlet aligns with the long-water-pump standard. Installation requires basic hand tools and takes approximately 15–30 minutes once the accessory drive is accessible. Pair it with a quality serpentine belt, proper belt tensioner, and your choice of alternator and power steering pulleys to complete a bulletproof cooling and accessory drive system.
