About this kit
4-Link Upgrade Kit, fitment-checked
Rough Country 595 is a 4-link upgrade for 2005–2015 Ford F-250 and F-350 Super Duty 4WD trucks already sitting on 6 to 8 inches of lift. It ships as three boxes — a 6 in upper arm kit, a matching set of 6 in lower arms, and the kit hardware box. The control arm drop brackets are what make it work, resetting caster so the truck steers and tracks the way it did stock. Bolt-on, about 4-6 hours.
Fitment runs 2005 through 2015 on the F-250 Super Duty and F-350 Super Duty in 4WD, plus 2005-2009 F-250 XL and XLT, across FX4, Lariat, King Ranch, Platinum, Cabela's, and Harley-Davidson Edition trims. The kit only works under 6 to 8 inches of suspension lift. Everything bolts on: upper arms, lower arms, and control arm drop brackets that put caster back where the factory geometry wants it, which is what keeps a lifted Super Duty tracking straight instead of wandering. Set aside 4-6 hours and pull the downloadable Rough Country installation guide first.
