1.75 x .120 wall DOM Tubing Welding Required Adds Jacking Points Along Rocker Area Put an end to squeaky dashboards and cracking roof panels on hardtop and t-top cars, and seriously enhance your chassis' handling and launch performance. Our truss-style framing system is constructed of 1.75 x .120 wall DOM tubing for serious, uncompromised rigidity. The frame rail connects to the front rear lower control arm mounting area and runs the entire length of the rocker panel, it ends at the rear side of the front wheel well. The main shaft is formed to fit the contour of the floor board, providing for weld contact area the entire length of the frame shaft, and no ground clearance loss. We don't stop there. Mid-shaft we install a Y off frame that connects the main frame shaft to the beefy front sub-frame at the transmission crossmember mounting area. This provides for the ultimate in chassis stiffening by utilizing a triangulated framing design. The frame rails also provide for an excellent jacking point. This is a weld in system that ships to you either bare, or with a brilliant and durable powder coated finish. If you've been looking for the ultimate sub-frame connection system for your third generation F-Body, you just found it! These SFCs are designed to be used on a single-cat or dual-cat y-pipe exhaust system. The passenger's side main shaft necks down in the front to allow proper y-pipe clearance. No exhaust or floor board modifications are necessary to install our SFCs. NOTE: Painted Red For Photographic Purposes, Ships As Bare Steel
