RK Suspension Super Duty 4 Link Upgrade is by far the strongest 4 link upgrade on the market for your F250/F350 or F450! The control arms are made from 2” solid alloy steel with ¼” thick laser cut steel and boxed 4 link mounting forks. They have 1.25” shank Pro-X Krawler Joints allowing for axle positioning and caster adjustment. The 4 Link Upgrade provides smoother on road ride than radius arms, provides more positive axle control than radius arms, and articulates much easier off-road than radius arms. For street, towing, trail use or having fun in the dirt, the 4 link upgrade is the way to go!
