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 complete kit (part # 97-382) includes the power steering pump with reservoir, mounting plate, hardline adapter, and pulley. Individual replacement parts are also available separately.
