Features
- Add-In Leaf Sets the Rate: An add-in leaf lets you change the rate, softer for daily driving or firmer for heavy loads and gear.
- Multi-Rate and Progressive Packs: ICON's leaf packs are progressively rated or multi-rate, so the spring stays compliant over small bumps and firms up as the load grows. Which design you get depends on the part.
- Made for the Rear: This spring works at the rear axle of the vehicle named in the title.
- Developed With ICON Systems: ICON develops its leaf packs alongside its suspension systems, so the springs suit ICON shocks.
- Built to Resist Sagging: Multi-leaf construction spreads the load across several thin leaves, which ICON says reduces spring fatigue and the sag that follows it.
- Tested on Road and Trail: ICON engineers test their suspension parts on the street, on the trail and under race conditions, the same development work behind its complete systems.
Description & Fitment
ICON's multi-rate leaf spring pack for the 2017-2025 Ford F-150, for 4WD models. ICON does not list it for models with onboard scales, Dynamic Bending Headlamps or Continuously Controlled Damping. It is a multi-rate pack with an add-in leaf, so the owner can set the rate up for an empty bed or for gear and a trailer. Read ICON's install sheet first: it includes drilling, cutting or trimming on this vehicle.

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 2017-2020 Ford F-150?
It fits when your vehicle matches one of these rows: 2017-2020 Ford F-150 (4WD; excludes onboard scales; excludes Dynamic Bending Headlamps; excludes Continuously Controlled Damping; Raptor only); 2021-2025 Ford F-150 (4WD; excludes onboard scales; excludes Dynamic Bending Headlamps; excludes Continuously Controlled Damping). If you are unsure about your trim or drivetrain, send us your VIN and we will check it against ICON's application list before you order.
Will I have to cut or drill anything?
Yes, ICON's install sheet for 198510 includes drilling, cutting or trimming. Read the sheet in the Installation section below before you start, or have a shop do the work.
Full pack, expansion pack or Add-A-Leaf: what is the difference?
A full pack replaces the whole spring. An expansion pack keeps the factory main leaf and replaces the secondary leaves. An Add-A-Leaf kit goes in place of the factory overload leaves. Each part's title tells you which one it is.
Will the ride get stiffer?
Not by design. ICON builds several of these parts with a softer rate than the factory leaves they replace, and its multi-rate packs let you set the rate for your load. The description of each part says how it is rated.
Which lift height should I choose?
Match the rear part to the rest of your ICON system. ICON lists the lift for each part in its title and in the fitment rows, and the front of the truck should be set up for the same lift.
What warranty applies?
ICON's published limited warranty applies to its leaf spring parts, for the original buyer and the vehicle they were first installed on. Contact us first if you need to make a claim, and we will open it with ICON for you.
Installation
- Jack
- Jack Stands
- Grinder W/ Cut-Off Wheel (Or Sawzall)
- Vise Grips
- C-Clamps
- Torque Wrench
- 9/16" Socket / Wrench
- 3/4" Socket / Wrench
- Rest on ICON's sheet
Here's the short version. Follow ICON's install sheet (below) for your vehicle's exact steps and torque values.
- Using a properly rated jack, raise the rear of the vehicle and support the frame rails with jack stands. Ensure the jack stands are secure and set properly before lowering the jack. NEVER WORK UNDER AN UNSUPPORTED VEHICLE.
- Remove the vent line from the axle and remove the vent fitting which also holds the brake line bracket to the axle tube. This will allow for additional flex in the lines so the axle may be drooped further.
- Using a 21mm and a 24mm, loosen the upper shackle bolt and remove the nut from the lower shackle bolt.
- Remove the shackle from the stock spring noting the orientation of the shackle and the direction of the bolt, the open part of the formed metal shackle should be toward the spring.
- Raise the axle up to the spring and align the center pins in the spring pad. Place the clamp plate on top of the leaf pack. Install the new U-bolts using the openings in the spring plate to locate them correctly.
- Torque the U-bolts 145 ft-lbs.
