Crankshaft Pulley Sb Chevy Lwp Double Lower Chrome is a crankshaft pulley for the listed engine/accessory-drive configuration. The crank pulley transfers engine rotation to belt-driven accessories, so groove count, diameter, water-pump style and belt alignment all have to match the rest of the drive system.
Verify the engine family, long/short water-pump configuration and accessory alignment before installation. Misaligned pulleys can throw belts and accelerate bearing or belt wear.
