The late-model factory power steering pump on the Mopar Gen III Hemi engines has too much pressure for the steering box on most older muscle cars & trucks. These special Saginaw type II power steering pumps produce the proper pressure, and the pulley is sized to operate the pump at the proper speed when used with the existing drive system on Gen III Hemi engines. The hardline adapter moves the power steering hose connection to a more accessible location for easy installation & maintenance. Black anodized finish on the mounting bracket and pulley
