Pulley - Power Steering Pump GM LS

The Holley Power Steering Pump Pulley for GM LS-Series engines is a precision-engineered component designed for builders and enthusiasts upgrading their LS powerplants with modern steering systems. This pulley interfaces directly with the power steering pump drive belt, transferring rotational energy from the engine's serpentine belt to pressurize your hydraulic steering system.

Whether you're building a restomod, swapping an LS into a classic platform, or upgrading your modern muscle car, a properly matched pulley ensures reliable steering assist without belt slip, vibration, or premature wear. Manufactured by Holley, a leader in automotive performance systems, this pulley is engineered to OEM specifications for LS-series compatibility, ensuring correct belt wrap and load distribution.

LS engine swappers and performance builders rely on Holley's pulley systems to maintain factory-grade steering feel in custom applications where original components don't fit or aren't available. The precise diameter and profile are critical—incorrect pulley sizing causes steering lag, belt chirp, or inadequate pump flow under high-demand conditions like tight parking or aggressive track work.
