Overview:

The Holley Low Pressure Power Steering Kit is engineered specifically for Mopar Gen III Hemi engine swaps in classic muscle cars and trucks. Factory power steering pumps on late-model Gen III Hemi engines produce excessive pressure that can damage older steering boxes. This kit addresses that issue by providing a specially designed low-pressure Saginaw type II power steering pump that matches the requirements of vintage power steering systems.

Designed to work seamlessly with the factory “car style” accessory drive system, this kit ensures proper pump speed and pressure, protecting your steering components while maintaining reliable power assist. The kit also features a hardline adapter that relocates the power steering hose connection to a more accessible position, simplifying installation and future maintenance.
