Genright's Legend Extreme four-link kit uses heavy-duty 1/4- and 3/16-inch-thick laser-cut and CNC-bent control arm mounts. The control arms are made from 2-inch x 1/4-inch-wall DOM tube. GenRight offers rod ends from various manufacturers. We opted to use QA1 Rock Ends from QA1 Motorsports. The four-link rear kit also eliminates the need for a rear track bar.
