Description
ICON Vehicle Dynamics 2021-2024 Ford F-150 4WD suspension systems are designed with maximum performance and the serious driver in mind. ICON's primary focus is to increase wheel travel and damping ability, which translates into outstanding vehicle control and ride quality.
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 Inchconversion Inch for your F-150 4WD. This Stage 4 system includes vehicle-specific tuned 2.5 Inch coilover shocks featuring CDXS equipped remote reservoirs for exceptional cooling properties and ICON-engineered coil springs for superior vehicle Inchfeel Inch through the range of travel.
These coilovers are height adjustable for 3.5-4.5 Inch of front lift, allowing the use of larger, more aggressive wheel and tire combos. Their combination with the ICON steering knuckles also allows for a 20 Percent increase in wheel travel compared to other ICON F-150 kits.
Features and Benefits:- Tubular Delta Joint Pro upper control arms not only add strength and durability, but help retain factory alignment specs, increasing caster over stock and allow for the extra lift height this system provides. ICON 2.5 Aluminum Series CDXS piggyback reservoir rear shocks utilize a vehicle-specific valving and offer increased damping and heat dissipation, balancing the performance of the truck from front to rear. ICON's exclusive Compression Damping Dual Speed (CDXS) valves are included for precisely dialing in your suspension performance. CDXS controls fluid flow under compression, with independent adjustability of high speed and low speed compression force. 10 discreet detented settings for both low and high-speed adjustment knobs allow separate adjustments for handling response and overall aggressiveness. ICON Multi-Rate Leaf Springs allow rear spring rate and ride height customization, improve ride quality, and reduce axle wrap by eliminating the factory rear blocks. Rear ride height is kept within an acceptable range using the ICON billet aluminum 1 inch lowering shackles. The ICON 2021-2024 F-150 4WD Stage 4 suspension system is an excellent choice for those looking to enhance the capabilities of their pickup.
- 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 Percent 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 Percent 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.
