Power Steering Pulley 2 Groove Keyway 66-76 GM

The Power Steering Pulley 2 Groove Keyway 66-76 GM by Billet Specialties is a precision-engineered replacement component designed for classic General Motors vehicles from 1966 to 1976. This pulley drives the power steering pump via V-belt engagement, maintaining consistent hydraulic pressure delivery to your steering system. Whether you're restoring a vintage Chevrolet, Pontiac, or Oldsmobile, or upgrading your classic GM muscle car's underhood aesthetics, this polished aluminum pulley combines form and function in one reliable package.

Machined from premium aluminum and finished to a mirror polished surface, this 2-groove pulley features a 6-inch diameter and a keyway design that ensures positive drive engagement with your Saginaw power steering pump shaft. The two-groove configuration accommodates standard V-belt systems common to mid-period GM applications, distributing load evenly across both ribs for smooth, efficient power transmission. At just 1.43 pounds, the lightweight construction reduces parasitic load on your engine while the polished finish resists corrosion and maintains its showroom appearance through years of underhood exposure.

Mechanics and restorers working on 1966–1976 GM platforms will appreciate this pulley's direct compatibility with Saginaw power steering pump assemblies, eliminating guesswork during installation. The keyed bore accepts standard shaft keys, providing the mechanical lock-up necessary for reliable operation under all steering loads. Ideal for frame-off restorations, engine rebuilds, or underhood cosmetic upgrades, this polished pulley delivers both OEM-correct function and custom appearance that elevates any classic GM engine bay.
