UMI's G-Body Anti-Roll bar is designed to help your hot rod leave the line flat and straight. The bars are manufactured from light weight 1-3/8” diameter tubular steel and feature three different rates (street/strip, strip with drag radials and full slick settings). UMI's tried and true CNC machined clamping system allows differential housing mounting on 2.75", 3" and 3.25" diameter housings. These can be bolted on, or welded for additional security. Since your car will be launching hard, we recommend welding. The double shear chassis mounts are held in place by four 3/8" fasteners and feature our exclusive reinforcement plate up top to help distribute the load. Drilling through the crossmember is required and a template /instructions are included. The house made hex adjuster allows pre-loading of the bar when used for drag applications so your car leaves straight no matter how much power you throw at it. This G-Body drag bar is available in beautiful red or black powder coat. Manufactured with pride in Philipsburg, PA - USA.
