Power Steering Pump Pulley Single V-Groove

The Power Steering Pump Pulley Single V-Groove (part number 8485B) is a precision-engineered replacement component for Tuff Stuff Saginaw-style power steering pump systems. This 5.8-inch diameter pulley is designed to accept a single V-belt configuration and features a press-on attachment method, making installation straightforward for technicians and experienced rebuilders working on classic muscle cars, hot rods, and performance engine builds.

Manufactured from steel with a durable black powder-coat finish, this V-belt pulley resists corrosion and wear in high-heat engine compartments. The single-groove design accommodates standard V-belts used in serpentine or traditional belt-drive configurations, ensuring reliable power transmission from the engine to the steering pump. The 5.8-inch diameter balances rotational efficiency with the torque requirements of Saginaw pump designs, commonly found in vintage and restomod applications where original equipment compatibility is essential.

This pulley is ideal for engine builders, restoration specialists, and enthusiasts rebuilding complete power steering systems on vehicles that originally equipped Saginaw pumps. Whether restoring a first-generation Camaro, Pontiac GTO, Chevelle, or similar era muscle car, or modernizing the cooling and accessory drive of a custom engine swap, this component delivers OEM-level fitment and performance. The press-on configuration allows for easy removal and installation without specialized tools, making it practical for both professional shops and serious DIY builds.
