GM Saginaw Power Steering Pump Single-Groove Steel Pulley - Black

This is a black steel single-groove V-belt pulley built for GM Saginaw power steering pumps with a 5/8" keyed shaft and a 5.750" outside diameter. It bolts onto Saginaw P-series keyed-shaft pumps used across a range of GM V-belt accessory drive systems, including small block and big block Chevy setups.

This pulley is a common replacement for a worn, cracked, or mismatched power steering pulley, and is also used when building a fresh Saginaw pump drive on street rod, hot rod, muscle car, and custom accessory drive builds. It's commonly paired with Saginaw pumps found on Camaro, Chevelle, Nova, C10, and GMC C/K trucks.

This pulley requires a keyed 5/8" Saginaw pump shaft and is not compatible with press-fit Saginaw pump shafts or GM Type II (TC) power steering pumps. Confirm shaft type, groove width, and pulley offset before ordering. Hardware is not included. Sold individually.
