ICON Vehicle Dynamics K63186 Stage 6 Coilover System with Leaf Springs 2.5-3" Lift

The ICON Vehicle Dynamics K63186 Stage 6 Coilover System is a comprehensive suspension upgrade engineered for the 2008–2010 Ford F-250/F-350 Super Duty 4WD. Delivering 2.5 to 3 inches of front lift over stock, this complete system is purpose-built to balance aggressive off-road capability with confident highway driving, making it equally at home on rough construction sites, dirt roads, and open freeway cruising.

At the heart of this Stage 6 system are ICON 2.5 Series CDC Valve (CDCV) remote reservoir coilovers, which provide ride-height adjustability across the full 2.5–3" lift range. ICON's CDC Valve technology delivers 10-position external tuning, allowing the driver to dial in the ride from soft comfort to firm performance without any disassembly. Front secondary shocks feature the same CDCV remote reservoir 2.5 Aluminum Series design for maximum front damping capacity, while the rear is handled by CDCV 2.5 Aluminum Series piggyback reservoir shocks. Remote and piggyback reservoirs increase fluid volume, extending consistent damping performance and reducing heat buildup under heavy or sustained use.

Key Features:

• 2.5 Series CDCV Remote Reservoir Coilovers — ride-height adjustable from 2.5–3" of front lift over stock
• CDC Valve (CDCV) Technology — 10-position externally adjustable damping on front coilovers, front secondary shocks, and rear shocks
• CDCV 2.5 Aluminum Series Remote Reservoir Front Secondary Shocks — maximizes front damping for loaded or tow applications
• CDCV 2.5 Aluminum Series Piggyback Reservoir Rear Shocks — vehicle-specifically tuned for the Super Duty platform
• Fabricated ICON Radius Arm System — fully boxed design with sealed pivot bushings for quiet, long-life operation; on-vehicle caster adjustment eliminates the need for caster bushings or drop brackets; profile optimized for up to 37" tire clearance at full steering lock
• Adjustable Front Track Bar with FK Rod End — allows on-vehicle axle centering to reduce deflection and correct front axle positioning after lift
• Dual Steering Stabilizer Kit — ICON 2.0 Aluminum Series stabilizers for smooth and controlled steering feel
• Alignment Cams — restore proper front caster geometry after lifting
• Rear Leaf Spring Expansion Packs with Blocks and U-Bolts — adds rear lift, reduces axle wrap, and improves rear compliance under load

The ICON Radius Arm System features a fabricated, fully boxed construction that provides exceptional strength while its optimized profile allows fitment of 37-inch tall tires without contact at full steering lock. Sealed pivot bushings minimize road noise and vibration feedback while ensuring durability. On-vehicle caster adjustment is built in, keeping front-end geometry correct without additional aftermarket hardware.

This system is ideal for Super Duty owners who demand a fully integrated, tuned suspension solution—whether towing heavy loads, navigating work-site terrain, or simply improving daily ride quality. All components are engineered and validated together as a complete package, ensuring optimal performance and fitment right out of the box.
