Our 4-point Chassis bar bolts directly to the frame of your Corvette for the ultimate in strength and ease of installation. Constructed from 4130 Chromoly our bars are designed to maximize chassis stiffness while maintaining rear visibility. We designed the main hoop to closely match the contour of the roof line for a great fit. The bar attaches to the structure of the Corvette at the base of the b-pillar and to the rear frame rails using riv-nuts and heavy duty Grade 8 flanged end bolts. Because we've designed this piece to attach at key points, you get the ultimate in stiffness for your Corvette! We include all of the installation hardware and a riv-nut insert tool.  Our bars ship as bare steel, but we show the bar here powder coated red.
