Borgeson offers an integral power steering conversion for your 1955-1957 Chevy. The Borgeson conversion box is a remanufactured GM Delphi 600 integral power steering gearbox. The Delphi 600 represents the latest generation of integral power steering gearbox technology with true modern power steering feel, feedback and a sporty 12.7:1 ratio. Borgeson has remanufactured this box to bolt directly to the factory mounting location and to fit the stock pitman arm. Conversion requires shortening the stock steering column. (Details below)
Cars with factory power steering will require drag link adapter #990001 or manual steering linkage.
STEERING COLUMN MODIFICATIONS
Floor shift cars with stock column will need to trim the outer column tube back to the firewall. Replacement steering column shaft #990008 can then be used with rag joint #055034 to connect to the conversion box.
Column shift cars with stock column will require extensive modifications and sectioning. We have available pre shortened stock columns for the 55-56 and 57 cars. Shortened stock columns require rag joint #055049 to connect to the conversion box.
Aftermarket columns. The available direct replacement aftermarket columns are the proper length to use with our box and will connect with either rag joint #055034 or 055052 depending on the column shaft. ididit Direct Replacement Columns Available.
