Remanufactured Power Steering Power Cylinder

The power cylinder is the external hydraulic ram that physically pushes or pulls the steering linkage on classic domestic vehicles (1960s–1970s). Mounted between the frame and the steering linkage, it receives high-pressure fluid from the control valve and converts that pressure into linear force at the linkage — the same job a modern integrated rack-and-pinion does in one unit. Common failure symptoms include fluid weeping from the cylinder rod seal, a soft or "mushy" feel at the steering wheel (internal piston bypass), assist that fades during prolonged steering input (worn cylinder bore), and visible damage to the cylinder body or rod.

Each cylinder is fully remanufactured to OE specification. The bore is honed and inspected for scoring, the piston is fitted with new seals, the rod is gauged for straightness and resurfaced if needed, and the rod-end seal is replaced. Every cylinder is hydraulic-tested for internal leakage and full-stroke performance before shipping. These fit vintage linkage systems of this era — verify your application in the fitment table.
