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 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.
