This is a 3/8" single-groove aluminum pulley built for GM Saginaw power steering pumps with a 5/8" keyed shaft. It bolts onto Saginaw P-series pumps used across a wide range of GM V-belt accessory drive systems, including small block and big block Chevy setups.

This pulley is a common replacement for a stripped, cracked, or mismatched power steering pulley, and is also used when building a fresh Saginaw pump drive on street rod, hot rod, 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) belt setup.

This 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 shaft type, bore diameter, and pulley offset before ordering. Hardware is not included. Sold individually.
