It bolts onto Saginaw P-series pumps used across GM accessory drive systems running a 1\/2\" belt, including small block and big block Chevy setups.\u003c\/p\u003e\n\u003cp\u003eThis pulley is a common replacement for a worn, cracked, or wrong-width pulley, and is also used when building a fresh Saginaw pump drive on street rod, hot rod, restoration, and custom accessory drive builds. It's commonly paired with Saginaw pumps found on Camaro, Chevelle, Nova, C10\/C20, and GMC C\/K trucks running a standard-drive (non-underdrive, non-overdrive) 1\/2\" belt setup.\u003c\/p\u003e\n\u003cp\u003eThis is a standard-drive pulley only — not underdrive or overdrive — and it is not compatible with press-fit Saginaw pump shafts or GM Type II (TC) power steering pumps. Confirm belt width, shaft type, and pulley offset before ordering, since this pulley is sized for 1\/2\" belts and will not properly seat a 3\/8\" belt. Hardware is not included.
