Lift Quoted on Stock Vehicles
Features
- Built in Stages: Each vehicle's systems climb from an entry stage upward, so the suspension can match a daily driver, a tow rig or a dedicated trail truck. The stage number tells you where a kit sits.
- Engineered Per Platform: ICON develops each system around one vehicle's geometry, choosing shock lengths, valving and spring rates for that platform instead of adapting a universal kit.
- Serviceable ICON Shocks: The ICON shocks in every stage are fully rebuildable and re-tunable, so worn seals or a change in how the truck is used means a rebuild or revalve, not new shocks.
- Track Bar and Steering Parts: Super Duty stages build on the solid front axle with parts such as radius arm drop brackets, a track bar drop bracket or adjustable track bar, and on some kits ICON's dual opposing steering stabilizer. The Kit contents table lists each stage's parts.
- Matched Coil and Leaf Springs: Many Super Duty stages include ICON dual rate front coil springs, and the 7" kits add progressive rate rear leaf springs, so the truck is lifted front and rear as one setup. The Kit contents table shows what yours includes.
- Lift Quoted on Stock Vehicles: Every lift range is quoted for a stock-equipped vehicle. Bumpers, winches and other added weight change where the height settles, so allow for them when choosing a kit.
Description & Fitment
Lead part K63144L is the ICON Stage Suspension System for the 2017-2022 Ford F-250 Super Duty and F-350 Super Duty. ICON lists it for 4WD and diesel models; the F-350 Super Duty row is single rear wheel only. At the entry end, Stage 4 (K63144L) includes steering stabilizer, track bar, block kit and rear U-bolt kit; Stage 6 (K63146L) moves up to front 2.5 remote reservoir shock pair, CDCV and radius arms. Choices run across Stage 4 through Stage 6, each its own ICON part number (3 in all). If yours differs, compare K62511L: 2017-2019, 2.5" lift.

About ICON Vehicle Dynamics
ICON Vehicle Dynamics designs and builds performance suspension for trucks and SUVs at its shop in Riverside, California. Engineering is led by Dylan Evans, its head engineer and a SCORE champion driver, and ICON tests its parts on the street, on the trail and under race conditions.
ICON's engineers begin with the result they want from a vehicle, then study the forces acting on it in motion, which is where the name Vehicle Dynamics comes from. Fabrication stays in ICON's own shop, from laser cutting and metal forming to CNC machining, welding and final assembly. ICON calls its suspension systems and shock absorbers the top choice for popular trucks and SUVs.
Authorized ICON Vehicle Dynamics dealer. Prestige Truck is an authorized ICON Vehicle Dynamics dealer, so every ICON part we sell is new and genuine. ICON's warranty is for the original retail buyer, on the vehicle the part was first installed on. Keep your Prestige Truck order receipt: we use it when we take a claim to ICON for you.
Frequently Asked Questions
Will this fit my 2017-2022 F-250 Super Duty?
Yes, if your vehicle matches a fitment row: 2017-2022 Ford F-250 Super Duty (4WD; diesel); 2017-2022 Ford F-350 Super Duty (4WD; diesel; SRW). Not for F-350/F-450 cab & chassis models. Not sure? Send us your VIN and we'll check it against ICON's listing.
What if my F-250 Super Duty has a different setup?
ICON makes other Stage Suspension Systems for it. The closest here is K62511L (2017-2019, 2.5" lift). The "Not for" box above lists the rest, each with its own fitment rows.
Which stage should I choose?
Start from how the vehicle is used. Entry stages improve ride quality and set the stance for daily driving, towing and light trail work, while higher stages add parts such as upper control arms, adjustable valving and rear links for harder off-road driving. The Kit contents table shows what each stage adds.
CDCV, CDXS or CDEV: what is the difference?
CDCV is an external knob with 10 compression settings from soft to firm. CDXS adjusts low-speed and high-speed compression separately. CDEV is an electronic valve that ICON Intelligent Control adjusts from onboard sensors, through the ICON app.
Will I need an alignment after installing?
Yes, whenever the system changes the front suspension. ICON's sheets call for a professional alignment, and many late-model vehicles also need their driver-assist cameras and sensors recalibrated.
How much does the lift change with a bumper or winch?
ICON quotes every lift range for a stock-equipped vehicle. A steel bumper, winch or other weight up front settles the vehicle lower in that range, so plan for it when you pick the lift option.

Warranty, shipping & returns
-
Warranty
ICON shocks and coilovers in this system carry ICON's 1-year shock warranty against manufacturer's defects, and ICON's other suspension components carry its Limited Lifetime Warranty.- Coverage belongs to the original retail buyer who owns the vehicle the parts were first installed on.
- A shock that fails in its first year goes to ICON for inspection and service. If ICON finds the cause was neglect, poor installation or anything other than normal wear and tear, the owner pays for labor, parts and shipping.
- ICON parts must go on as the complete kit shown in ICON's application guide. Swapping out or leaving off a required part voids the warranty.
- ICON repairs or replaces a defective part, at its discretion. Removal, reinstallation, freight and incidental or consequential costs are not covered, and parts that wear in normal use are not treated as defective.
- Not covered: finish (including finish marks from shipping), alterations or modifications, installation that departs from ICON's instructions, racing use, police, taxi, government or commercial vehicles, and sales outside the United States and Canada.
- To claim, contact us first with your order number and a short description of the problem. We open the claim with ICON for you, and your Prestige Truck receipt is the proof of purchase ICON asks for.
-

Inspect on delivery
A stage system arrives in several cartons: open every box when it lands, check each part and hardware bag against ICON's parts lists, and photograph any carton damage before you sign or start the install. Check it as soon as it arrives.- Look for crushed ends, punctures or tears in the carton.
- If something looks wrong, take photos of the box and the parts (and if a driver asks you to sign, note the damage on the receipt).
- Open the box and check the parts against the parts list before you install.
