ICON Vehicle Dynamics K93144 - 21-24 FORD F150 4WD 3.5-4.5" STAGE 4 SUSPENSION SYSTEM BILLET CDCV

ICON suspension systems lift your Ford F-150 4WD while improving ride quality and performance. With endless hours spent testing and tuning our suspension components and shocks, you’ll have the best suspension solution on the market.

ICON Vehicle Dynamics 2021-2025 Ford F-150 4WD suspension systems are designed with maximum performance and the serious driver in mind. ICON engineers’ primary focus is to increase wheel travel and damping ability, which translates into outstanding vehicle control and ride quality both on and off-road. To achieve this, these systems include high-strength CNC machined ductile iron steering knuckles that replicate the suspension geometry of the F-150 Tremor and are effectively a Tremor “conversion” for your F-150 4WD. This Stage 4 system includes vehicle-specific tuned 2.5” coilover shocks featuring CDCV equipped remote reservoirs for exceptional cooling properties and ICON-engineered coil springs for superior vehicle “feel” through the range of travel. These coilovers are also height adjustable for 3.5-4.5” of front lift over stock, allowing the use of larger, more aggressive wheel and tire combinations. Their combination with the ICON steering knuckles also allows for a 20% increase in wheel travel compared to other ICON F-150 coilover kits. Billet aluminum Delta Joint PRO upper control arms on the F-150 not only add strength and durability, but help retain factory alignment spec range, offer on-vehicle caster/camber adjustment, and allow for the extra lift height this system provides. ICON 2.5 Aluminum Series CDCV piggyback reservoir rear shocks utilize a vehicle-specific valving and offer increased damping and head dissipation, balancing the performance of the truck from front to rear. The included ICON CDC Valves are externally adjustable valves that restricts oil flow into the reservoir which creates 10 levels of compression damping force ranges. The ICON Vehicle Dynamics 2021-2025 F-150 4WD Stage 4 suspension system is an excellent choice for those drivers looking to enhance the capabilities of their pickup on the road as well as in the dirt. This system features upper control arms with ICON's patented Delta Joint PRO. Delta Joint PRO is ICON's innovative new suspension articulation joint which combines the durability and longevity of factory style ball joints with performance and strength that exceeds traditional motorsports-style ball joints. The Delta Joint PRO features a new rebuildable, serviceable design in which any component may be removed, inspected, and replaced without having to purchase a whole new joint. Strength and durability are improved by using a larger ball with 56% more bearing surface than our standard Delta Joint, along with improved lubrication sealing. But improved performance is at the heart of the Delta Joint PRO, with a full 90 degrees of articulation, from one extreme to the other. This represents a 14% improvement in range of motion, over the highly capable original Delta Joint, allowing for maximum bind-free suspension movement through the complete range of travel. The Delta Joint PRO is built to take the abuse, with a chromoly ball and shaft that has a bearing surface hardened to Rockwell C 55. The replaceable races are made of graphite-impregnated sintered metal, machined to the finest tolerance to provide a flawless, metal-to-metal bearing interface. We also redesigned the lubrication system, with lubricant channels that distribute grease more efficiently without extending past the bearing seal.
