Power Steering Box, 500 series

The 500 Series power steering conversion gearbox is a key part of a modern, high performance power steering system. This 14:1 ratio unit provides superior control and feedback, thanks to low friction recirculating ball gears. An open-centered rotary valve provides smooth operation while retaining excellent road feel and steering response. For the 1958-64 full-size Chevrolet, the 500 Series is a direct replacement for the manual steering box and compatible with the original pitman arm. Mounting bosses are integrated into the casting, lining up without shims and eliminating the need for an external bracket. Works with original and aftermarket steering columns and sway bars.

Important: Must use rag joint GB50730 when replacing original power steering box with 500 series power steering box.
