The custom four-link front suspension has 2-inch-diameter, 0.250-inch-wall DOM links (each fitted with a pair of Currie Johnny Joints) that are bolted to custom mounts made from 0.250-inch-thick steel; FOA 16-inch-travel remote-reservoir coilovers; FOA 2.5-inch-diameter, 4-inch-travel bumpstops; a pair of Poly Performance limiting straps; and a Rock Equipment sway bar with custom brackets and links. This suspension helps to give the axle 6 inches of uptravel and 10 inches of downtravel. Davis says this front suspension also contributed to the Jimmys score of 770 points on a 30-degree RTI ramp.
