The '09 Dodge 1/2-ton suspension has not changed much from the '02-'08's IFS design. It even uses the same knuckles in fact. But as close as it is, Dodge did change some things. For one, the new Ram's suspension does not travel straight up and down as the previous generation's did, and instead travels slightly rearward as it compresses.Superlift uses a replacement knuckle to keep the upper A-arm and steering tie rods in their stock locations. Anti-sway bar links and a subframe drop bracket allow for the 6 inches of lift.
