Power Steering Conversio n Kit 58-64 Chevy Box U-

The Power Steering Conversion Kit 58-64 Chevy Box U- by BORGESON transforms the steering response and driver control of classic 1958–1964 Chevrolet A-Body vehicles by upgrading from manual to power-assisted steering. This conversion kit addresses the heavy steering effort inherent in early manual boxes, significantly reducing driver fatigue during extended driving and improving maneuverability in parking and low-speed situations. Classic car enthusiasts and restoration specialists rely on this kit to modernize steering feel while maintaining authentic underhood appearance and original mounting points.

The kit features a Delphi 600 power steering box fabricated from cast iron, engineered specifically for GM A-Body chassis geometry and steering column integration. Power steering operates by channeling hydraulic pressure through internal porting within the box, reducing the mechanical advantage required at the steering wheel—typically cutting steering effort by 60–70% compared to manual operation. The conversion includes all necessary joints and shaft components to facilitate seamless integration with the existing steering column and tie-rod linkage, requiring only standard hydraulic pump and hose routing during installation. Iron construction ensures durability and heat dissipation under continuous operation, while the Delphi engineering maintains precise steering response and directional stability expected in vintage Chevrolet platforms.

Restorers upgrading 1958–1964 Chevy A-Body models—including Bel Air, Impala, and Chevelle platforms—will find this power steering conversion kit essential for modernizing driving dynamics without sacrificing original aesthetic integrity. Installation requires mechanical competency in steering system work and coordination with engine-mounted pump installation; professional automotive technicians familiar with mid-century Chevrolet chassis should handle fitting to ensure proper alignment and leak-free operation. At 30.24 lbs, the completed assembly is manageable for under-vehicle positioning, and the compact footprint (16.5 x 9 x 16.65 inches) accommodates standard engine bay layouts of the era.
