Stage 2 Billet 3.5-4" Suspension Kit

The Stage 2 Billet 3.5-4" Suspension Kit by ICON Vehicle Dynamics is a top-tier upgrade for the 2021+ Ford F-150 4WD. Engineered for maximum performance and serious drivers, this kit is designed to enhance both on-road and off-road capabilities. Its core features include high-strength CNC machined ductile iron steering knuckles that replicate the suspension geometry of the F-150 Tremor, effectively converting your F-150 into a Tremor. This kit offers a significant 3.5-4.5" front lift height over stock, allowing for larger, more aggressive wheel and tire combinations.

Technical Specifications and Features

The Stage 2 Billet 3.5-4" Suspension Kit is equipped with vehicle-specific tuned 2.5" coilover shocks featuring an internal reservoir for exceptional cooling properties. These coilovers are height adjustable, providing the flexibility to choose the perfect ride height. The Billet Upper Control Arms with Delta Joint PRO ball joints not only add strength and durability but also help retain factory alignment spec range and offer on-vehicle caster/camber adjustment. This kit includes ICON 2.5 Aluminum Series piggyback reservoir rear shocks that offer increased damping and head dissipation, balancing the performance of the truck from front to rear. Key features include:
  • High-strength ductile iron steering knuckles for enhanced suspension geometry.
  • Adjustable coilovers for 3.5-4.5" front lift height over stock.
  • Billet Upper Control Arms with Delta Joint PRO for added strength and alignment spec range.

This kit offers a 20% increase in front wheel travel compared to other ICON F-150 coilover kits, providing improved ride quality and vehicle control. With no change in towing capacity, this system is perfect for those who need a reliable and capable pickup. The corrosion-resistant CAD plated coilover shock bodies and FK rod end bearings ensure extended longevity and minimal deflection. This 100% bolt-on system requires no drilling, cutting, or welding, making installation straightforward. The Stage 2 Billet 3.5-4" Suspension Kit is ideal for off-road enthusiasts, daily drivers, and anyone looking to elevate their F-150's performance.
