GM Saginaw Power Steering Pump 3/8" Single-Groove Aluminum Pulley - Black

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.

 

Aluminum Pulley Sized for Saginaw's Keyed Pump Shaft
Machined from aluminum with a 3/8" single-groove design, this pulley is built to mount on the keyed 5/8" shaft used by GM Saginaw power steering pumps, giving you a precise, lightweight replacement or upgrade over a worn or damaged factory-style pulley.

Keeps Belt Tension Consistent
A worn, cracked, or mismatched pulley can cause belt slip, noise, or inconsistent power steering assist. This single-groove aluminum pulley is sized to standard-drive specs, helping maintain proper belt alignment and tension across your Saginaw pump's accessory drive.
