Late-model Super Duty trucks are popular heavy-duty rigs and some owners like to use them to hit the dirt. Rough Country has a lift solution for those wanting bigger tires and improved off-road capabilities. We dropped by Bullet Proof Diesel to see their crew install a 6-inch kit on a 2005 Ford Super Duty. The kit replaces the two factory radius arms with a four-link setup with link arms that use polyurethane bushings. The linked front suspension offers caster adjustment with adjustable lower arms and increased articulation over the stock configuration.
Del Wamsley and Jacob Lopez completed the installation in four hours flat using one of the lifts in their shop. The work could be done in a driveway with jackstands and a large floor jack; it would just require more time for completion.
With the lift install finished and 37-inch tires installed, we took the truck for a drive. The ride was just slightly firmer than stock, and felt stable on the highway with the new lift height. In the dirt, the spring rates offered a significant improvement in control without any harshness. The suspension soaked up terrain far better, and hill climbs were easier with the added flex and new rear leaf springs. For those looking for a Super Duty suspension upgrade with the ability to fit larger rubber, this might be just what you need.
