GM Pulley 6 Rib Alum Power Steering

The GM Pulley 6 Rib Alum Power Steering by March Performance is a lightweight aluminum replacement pulley engineered for General Motors vehicles requiring power steering accessory drive optimization. This component is essential for builders and enthusiasts looking to reduce overall engine accessory weight, improve underhood aesthetics, and fine-tune serpentine belt systems during engine rebuilds or performance modifications. Whether you're restoring a classic GM muscle car or upgrading a modern platform, this pulley delivers precision engineering in a compact 6.3 x 4.7 x 6.4-inch form factor.

Constructed from durable aluminum alloy, the GM Pulley 6 Rib features six-groove serpentine belt compatibility, ensuring proper belt tension and power transmission to your vehicle's steering pump without slippage or wear. The March Performance pulley design integrates seamlessly into OEM accessory drive configurations while reducing rotating mass—a critical factor when building high-revving engines or implementing lightweight performance builds. At just 1.6 pounds, this pulley minimizes parasitic load on the crankshaft compared to heavier cast-iron factory alternatives, contributing to improved throttle response and engine efficiency without compromising steering system reliability or pump flow.

Ideal for restomod builders, vintage drag racers, and street performance enthusiasts, this pulley suits any GM application where weight reduction and belt drive modernization matter. Installation requires proper serpentine belt routing verification and tension adjustment to factory specifications—standard procedure during any accessory drive overhaul. Ensure compatibility with your specific GM engine generation and power steering pump design before ordering; March Performance's engineering guarantees correct rib pitch and diameter for OEM fit and function.
