Borgeson Street & Performance Quick Ratio Chevy C10 Power Steering Box. Borgeson Universal now offers an all new modern quick ratio power steering box to replace the Saginaw/Delphi 800 series in 68-86 Chevy C10 trucks. This all new power steering box has a quick 12.7:1 ratio with firm modern steering feel. The Borgeson Street & Performance power steering box will bolt directly to the stock location and fit to the original power steering pitman arms. Trucks switching from manual steering will require a power steering pitman arm. Steering box includes adapters to be able to use either O-ring or flare style hose connections.
