Take your third-generation Ford Super Duty to new heights with Rough Country's 6-inch Radius Arm Coilover Conversion Suspension Lift! This all-inclusive kit comes with everything you need for a total transformation of your truck. Run up to 37in tires while preserving the smooth, factory ride quality with this impressive upgrade. When changing a vehicle's suspension, the key to preserving ride quality is keeping the geometry of all suspension components as close to their factory angles as possible. Rough Country's new 6-inch Radius Arm Suspension Lift features a set of ultra-durable Radius Arms, precision fit to bolt right into the factory mounts for an easier install and a more factory-like angle. At 27lbs each, these beefy, upgraded Radius Arms dwarf stock equipment and feature durable Clevite Rubber Bushings for maximum vibration absorption. Rough Country's 6 in Radius Coilover Conversion Lift Kit features top-mounted reservoir brackets and coil-over mounts constructed from 1/4-inch steel. Utilizing this conversion kit you're removing the factory independent coil shock and coil set-up and replacing it with a massive 2.5in piston, nitrogen-charged, 8-stage adjustable Vertex Coilover. Rough Country's Vertex Coilovers feature a monotube design with an external reservoir for increased oil capacity and damping sensitivity. When it comes to investing in a high-end kit, you'll be pleased to find that Rough Country's 2.5in piston design is beefier and offers an impressive 56% greater fluid capacity than the average reservoir shock. Each kit is paired with a monotube shock that provides optimal damping control. Requiring cutting and drilling to install, an estimated timeframe of 6-10 hours is recommended to complete. This full kit can be installed at home and can be completed efficiently and quickly! Rough Country's 6-inch Radius Arm Coilover Conversion Suspension Lift Kit is backed with a limited lifetime replacement warranty towards manufacturer defects.
