UMI Performance Sway Bars allow your G-Body chassis to maintain grip in the corners without rear tire lift. These sway bars are solid 3/4" diameter for specific use in autocross or road race applications. A CNC-machined clamping system accommodates differential housing installation on 2.75", 3", and 3.25" diameter housings (can be bolted on or welded for added security). Double shear chassis mounts are secured by four 3/8" fasteners (requires drilling through the crossmember & includes template/instructions).Sway Bars are adjustable in three different positions for a stiffer or softer rate depending on the course layout.
