This ICON V.S. 2.5 Series coilover kit is built for the 2017-2026 Ford F-250 Super Duty and F-350 Super Duty, with vehicle-specific valving and ride height you set by adjusting spring preload. Adjustable lift opens room for larger wheel and tire packages, within the limits listed in the fitment notes for your vehicle. This listing covers 2.5 Series coilover part numbers 61721E.

What's Included:

The ICON 2.5 Series coilover assemblies for the position shown, each with its ICON coil spring fitted
The reservoirs, mounts and hardware listed for your part in the Kit contents table

Some applications need other parts, such as ICON upper control arms above a set lift height, a differential drop, longer CV axles, or an IIC module for CDEV coilovers. Those are sold separately and listed in the notes for your vehicle. Wheels and tires shown in photos are not included.

Features

Height You Can Adjust
A threaded spring perch lets the ride height be set within the range ICON lists for the vehicle, so you can level the stance or make room for larger tires. ICON sets each coilover at its recommended height before it ships.

A Larger 2.5" Shock Body
The 2.5" body and its larger piston area than stock components improve damping and ride quality on everything from pavement to washboard and rock.

Valved for the Vehicle
ICON tunes the shock length and valving for each application, giving a sport-tuned feel on the road with the control to handle rough ground off road.

ICON Engineered Springs
Each assembly carries a coil spring engineered by ICON for the vehicle, with firmer 700 lb/in or heavy-rate springs on many applications for vehicles that carry extra weight.

Reservoirs and Adjusters
Remote reservoir versions keep operating temperatures lower during extended off-road use, and CDCV, CDXS or CDEV valves add compression adjustment on the applications that offer them.

Built to Be Rebuilt
The coilovers are fully rebuildable and re-tunable, so the same assemblies can be serviced or revalved over a long working life.

Warranty, Shipping & Returns

Warranty. ICON warrants its shock absorbers, including the shock in each coilover, for 1 year against manufacturer's defects. A shock that fails in its first year of ownership must be shipped to ICON Vehicle Dynamics for inspection and service, and if ICON finds the failure came from neglect, improper installation or anything other than normal wear and tear, the owner pays the service costs, including labor, parts and shipping. Coverage is for the original retail purchaser who owns the vehicle the part was first installed on, and ICON repairs or replaces a defective part at its discretion. Finish, alterations, installation contrary to ICON's instructions, racing use, police, taxi, government or commercial vehicles, and sales outside the United States and Canada are not covered, and neither are removal, installation or freight costs. The shocks leave ICON charged with nitrogen: releasing that pressure can make a shock malfunction, and a failure caused by low nitrogen pressure is not covered. Shipping. The carrier and ship method are set by the size and weight of the cartons when the order is placed. Larger orders can arrive in more than one carton. Inspect on delivery. Open every carton when it arrives and check each shock, reservoir and hardware bag against the parts list in the ICON guide before you start. Note any visible carton damage on the delivery receipt and photograph it, because damage reported later is much harder to claim. ICON notes that some finish damage can happen in shipping and is not covered by its warranty.

Returns. Unused items in their original packaging can be returned within 30 days of delivery. If an item arrives damaged, defective or wrong, return shipping is on us. See our Returns & Refunds Policy, or email support@prestigetruck.com with any question.

About ICON Vehicle Dynamics

ICON Vehicle Dynamics is a performance suspension manufacturer in Riverside, California, building aftermarket suspension components and shock absorbers for vehicles and SUVs since 2008. Its engineering is led by head engineer and SCORE champion driver Dylan Evans, and the team starts each project by defining how the finished vehicle should drive, then studies the forces acting on it in motion to decide what to change. Laser cutting, metal forming, CNC machining, welding and assembly all happen in house, and products are tested in real-world use as well as race conditions.

The V.S. 2.5 Series coilover is the front-end building block of many ICON suspension systems, and it is also sold on its own for owners who want adjustable height and better damping without a full lift kit. ICON designs its 2.0 Aluminum Series and 2.5 Series rear shocks to pair with these coilovers so the vehicle is balanced front to rear.

Set your own ride height

ICON 2.5 Series coilovers arrive at the ride height ICON recommends, and the threaded spring perch lets you raise or lower the vehicle within the range listed for it. That makes it simple to level the stance or clear a larger tire. The guide for each vehicle sets the maximum preload to keep ride quality intact.

CDEV for the Super Duty

ICON shows its CDEV shock system for 2005 and newer Ford Super Duty trucks, adjusted from a phone instead of under the truck.

Adjusters for every driver

Many applications offer CDCV with 10 compression settings on a knob, CDXS with separate high-speed and low-speed compression knobs, or CDEV for electronic adjustment from the cab. Fixed-valve versions keep ICON's own tune with nothing to set.

Electronic damping with CDEV

ICON shows how CDEV and ICON Intelligent Control change compression damping on the move, with settings made in a phone app.

Frequently Asked Questions

Straight answers on specs, fit and support

How much lift do these coilovers give?

It depends on the vehicle. Each part lists its adjustable range in the Lift option, and ICON rates those heights for a stock-equipped vehicle. Added weight from a bumper or winch can lower where the vehicle sits within the range.

Do I need an alignment after installing them?

Yes, after front coilovers. Changing front ride height changes the suspension geometry, and ICON's guides call for a professional alignment. Retorque all hardware after the first 100 miles too.

Do I need new upper control arms?

On some vehicles, above a certain lift height, and on extended-travel versions. ICON lists the requirement in the notes for each vehicle, for example where lifting beyond about 2" calls for ICON upper control arms.

CDCV, CDXS or CDEV: what is the difference?

CDCV adds a knob with 10 compression settings. CDXS gives separate high-speed and low-speed compression knobs with 10 settings each. CDEV adjusts compression electronically through ICON Intelligent Control, which needs its IIC module and the matching CDEV parts listed for your vehicle.

When should I choose the 700 lb/in or heavy-rate springs?

Only when the front of the vehicle carries added weight, such as a steel bumper and winch. ICON recommends the 700 lb/in rate only when extra weight sits on the front end; on a stock front end the standard spring rides better.

What warranty comes with the coilovers?

The shock in each coilover carries ICON's shock absorber warranty: 1 year against manufacturer's defects for the original purchaser, with the shock sent to ICON for inspection. Racing use and improper installation are excluded.
