Description

UMI's G-Body 3/4" solid rear sway bar is designed for autocross and road racing, preventing inside rear wheel lift while enhancing rotation. It features a lightweight 3/4" solid, CNC bent 4140 CrMo construction with three adjustable rates: 346, 262, and 205 lb/in. The design ensures compatibility with various rear ends, including Factory OEM 7.5, GN 8.5, 12-Bolt, 9", M9, and S60, accommodating 2.75", 3", and 3.25" axle tube diameters. It includes heavy-duty CrMo spherical rod ends, zinc-plated u-bolts, laser-cut mounts, a billet steel hex adjuster, and greaseable polyurethane bushings. The installation is 100% bolt-in, though drilling is required for the double shear chassis mounts.
