1:1 Pulley Kit for use w/o Power Steering

The 1:1 Pulley Kit for use w/o Power Steering from ALLSTAR PERFORMANCE is a critical component for engine builders and performance enthusiasts eliminating hydraulic power steering systems. This pulley conversion kit allows you to run a serpentine belt drive system at true 1:1 crankshaft-to-accessory ratio, ideal for vehicles undergoing complete steering system modifications or weight-reduction builds. Whether you're installing a manual steering box, upgrading to a modern electric power steering conversion, or simply removing unnecessary hydraulic components, this kit provides the proper mechanical engagement your accessory drives demand.

At 1:1 ratio, your water pump, alternator, and other belt-driven accessories rotate at identical speed to the crankshaft, eliminating the over-drive or under-drive characteristics typical of stock serpentine systems. This direct-drive design ensures optimal cooling efficiency and charging output without the parasitic losses or complexity of variable-speed pulleys. The kit's compact dimensions (8.6 x 8.5 x 8.75 inches) and manageable 5.13 lb weight make integration straightforward into tight engine compartments, while precision machining ensures accurate belt tracking and minimal vibration across RPM ranges from idle to extended high-speed operation.

Street rod builders, vintage truck restorators, and circuit-focused competitors benefit most from this conversion, particularly when combining manual or electric steering with custom cooling and charging demands. Installation requires removal of the factory power steering pump and idler pulley arrangement, followed by proper belt tensioning—a straightforward procedure for experienced mechanics familiar with serpentine systems. Verify your specific engine block and crankshaft configuration before ordering to ensure proper fit and clearance with your existing water pump and alternator placement.
