S&W frame rails are designed for the do-it-yourselfer wishing to narrow his or her rear frame section to accommodate modern drag race or pro/street tires. Made from 2″x3″x.083″ wall mild steel rectangular tubing, and mandrel formed on our own computer controlled machinery, they are substantially lighter than stock rear frames. These frame rails offer the do-it-yourselfer the added savings of less expensive U.P.S. shipping charges. All S&W frame rails are sold in pairs.
S&W OEM UPGRADE rear frame rails are designed for applications where retaining the rear floor pan is either more practical or more desirable. These rails are designed to follow the original rear floor contour and install with minimal cutting or modifications. These rails are available to either retain the original rear leaf springs (if so equipped) or in coil-over versions for the builder wishing to update his rear suspension with the addition of coil over shocks or an S&W Pro/Series 2000 shock & spring kit. Sold in pairs. S&W frame connectors are designed to be used in conjunction with our rear frame rails. They provide additional stiffness to your stock bodied car by tying the front subframe to the rear frame rail. O.E.M Upgrade Part.
