Conquer with Confidence: Elevate your fifth-generation Ford Super Duty with Rough Country's 4.5-Inch Coilover Suspension Lift Kit. Built for off-road warriors and everyday drivers alike, this performance-driven upgrade delivers aggressive ride height without sacrificing comfort. Run up to 35-inch tires and take command of any terrain with confidence and control. Adjustable Performance, Superior Ride: Fine-tune your stance with fully adjustable Vertex coilovers designed for maximum clearance and responsiveness. These 2.5-inch, nitrogen-charged monotube coilovers feature 8-stage adjustability and external reservoirs offering 56% more fluid capacity for cooler, more consistent performance. A secondary V2 monotube shock at each front corner creates a dual-shock setup that enhances stability and control on every journey. Stronger by Design: Heavy-duty 1/4-inch fabricated coilover mounts ensure maximum strength and durability under the harshest conditions. Tubular radius arms feature a massive 2-inch outer diameter, precision-fit for OEM mounts, maintaining a factory-like suspension angle while delivering unmatched strength. Durable rubber bushings help absorb vibration, promoting a smoother, quieter ride on or off the road. Enhanced Rear Suspension: Heavy-duty fabricated lift blocks outperform cast alternatives in strength and reliability. Anti-axle wrap rear blocks preserve factory ride quality while eliminating unwanted axle movement. For all-terrain control, upgrade with optional V2 or Vertex rear shocks to complete a four-corner performance package. Hassle-Free Installation: This system is fully bolt-on, no cutting or drilling required. Top-mounted reservoir brackets ensure clean, secure placement, while front-to-rear leveling eliminates factory rake for a more aggressive, balanced stance. Boosted ground clearance improves off-road capability, and enhanced suspension geometry keeps your Super Duty performing at its best. Backed by Confidence: Covered by Rough Country's Limited Lifetime Replacement Warranty, this 4.5-Inch Coilover Lift Kit offers peace of mind with every mile. Drive harder. Ride smoother.
