400159 | Rough Country 4.5 Inch Coilover Conversion Lift Kit For Ford F-250/F-350 Super Duty 4WD | Vertex Adjustable Shocks

Conquer with Confidence: Elevate your fifth-generation Ford Super Duty with Rough Country's 4.5-Inch Coilover Suspension Lift Kit. Designed for serious off-roaders and daily drivers alike, this performance-driven system delivers aggressive ride height while preserving smooth, factory-like comfort. Run up to 35-inch tires with confidence and dominate terrain like never before.

Precision Engineering. Premium Ride: Fine-tune your stance and clearance with fully adjustable Vertex coilovers that dramatically enhance damping performance for a smoother, more responsive ride. Each coilover features an 8-stage adjustable, 2.5-inch piston with nitrogen-charged monotube design and external reservoirs offering 56% more fluid capacity than standard shocks for unmatched heat dissipation and consistency. A secondary V2 front monotube shock adds even more stability and control, making this a dual-shock setup that stands above the rest.

Built to Outlast: Heavy-duty 1/4-inch fabricated coilover mounts ensure maximum strength and durability under the harshest conditions. Radius arm drop brackets provide proper caster correction to maintain factory-like handling, while heavy-duty fabricated rear lift blocks deliver superior strength compared to cast alternatives. Rear blocks are also custom-engineered to prevent axle wrap, preserving your ride quality mile after mile. Pair with optional V2 or Vertex rear shocks for four-corner performance you can feel.

Smarter Installation. Better Results: This bolt-on system is designed for a hassle-free setup no cutting or drilling required. Top-mounted reservoir brackets offer clean, secure placement, and front-to-rear leveling eliminates factory rake for a more aggressive, balanced look. Boosted ground clearance allows you to tackle trails with ease, while enhanced suspension geometry keeps your Super Duty performing as it should.

Peace of Mind Included: Backed by Rough Country's Limited Lifetime Replacement Warranty, this 4.5-Inch Coilover Suspension Lift Kit is built to last and protected from structural or workmanship defects from day one. Drive harder, ride smoother, and lift smarter with Rough Country.
