1963-82 Corvette Manual Steering Box Rebuild Kit
Flaming River offers a parts kit to rebuild your own box. Most rebuilt boxes on the market only have new
bearings, races and seals installed. The worn nut and sector, which are the critical parts that are needed for
that new steering response, are not available new so the old
parts are recycled into rebuilt boxes. We new offer all new
internals so you can rebuild your box and get back on the road
safely!
Note: Re-manufacturing your own steering box requires
technical expertise and some machining may be necessary
(i.e. bushings.)
