ICON V.S. 2.5 Series Front Coilover Conversion Kit for 2005-2026 Ford F-250/F-350 Super Duty 4WD with CDCV

The ICON V.S. 2.5 Series Front Coilover Conversion Kit (SKU 61721C) is a bolt-in front suspension upgrade for 2005–2026 Ford F-250 and F-350 Super Duty 4WD trucks, delivering 4–5.5 inches of front lift over stock on a crew-cab diesel baseline, with exact lift range varying by model year, powertrain, and Tremor package status. The 2.5-inch remote reservoir coilover body is paired with ICON's Compression Damping Control Valve (CDCV) for 10 positions of external compression adjustment.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Ride-Height Adjustability Built Into the Design

Because the coilover replaces the factory spring and shock as a single unit mounted in the OE coil bucket, ride height can be dialed in by adjusting preload on the coilover rather than swapping springs or shimming the factory strut. That means a driver who runs the truck loaded for a work week and unloaded on weekends can tune the front stance without pulling the suspension apart. ICON-engineered coil springs are guaranteed for life against sagging or breakage, so the height set at install stays consistent over time.

10-Position Compression Damping at Your Fingertips

The CDCV (Compression Damping Control Valve) controls fluid flow under compression with a single external knob, giving 10 distinct settings between a supple street tune and a firm off-road setting. The adjustment happens at the reservoir, with no shock rebuild or suspension shop visit required to switch between highway cruising, rock crawling, and high-speed desert running. Vehicle-specific valving is set at the factory for the F-250/F-350 platform, so the baseline tune is calibrated for Super Duty weight and geometry before the CDCV range is even applied.

Fully Serviceable, Secondary-Shock Ready

CAD-plated coilover shock bodies with 7/8-inch shafts resist corrosion, and the fully rebuildable and revalveable construction means the kit can be refreshed or retuned rather than replaced when service intervals arrive. FK Rod End bearings reduce deflection and extend longevity at the mounting points. Secondary shock options are available for additional damping capacity; adding a 2.5 Series or 3.0 Series remote reservoir secondary shock requires reservoir doubler kit part number 611003, sold separately.

• CDCV: 10 positions of external compression damping adjustment via knob at the reservoir
• ICON-engineered coil springs: lifetime guarantee against sagging or breakage
• FK Rod End bearings: extended longevity and minimal deflection at mounting points
• CAD-plated shock bodies: corrosion-resistant finish, 7/8-inch shafts
• Fully rebuildable and revalveable: serviceable design for long-term ownership

Specifications

Who This Is For and Isn't

This kit suits 2005–2026 Ford F-250 and F-350 Super Duty owners running 4WD who want a significant front lift with tunable compression damping and a fully serviceable shock they can rebuild rather than replace. It is compatible with factory wheels and tires, and ICON notes recommended aftermarket wheel and tire sizes for owners upgrading both.

This kit does not fit 2WD Super Duty models. Lift heights stated are for a stock-equipped 4WD Crew Cab diesel; actual lift on other cab, bed, or powertrain configurations will differ. Installation requires removal of the coil centering cup in the factory coil bucket and recalibration of Advanced Driver Assistance Systems (ADAS) after install. Adding a 2.5 Series or 3.0 Series remote reservoir secondary shock requires reservoir doubler kit 611003, sold separately.

Common Questions

Does this kit fit 2WD F-250 and F-350 trucks?

No. The ICON V.S. 2.5 Series Front Coilover Conversion Kit (SKU 61721C) fits 2005–2026 Ford F-250 and F-350 Super Duty trucks equipped with 4WD only. It is not compatible with 2WD Super Duty models.

How much front lift will I get, and does it vary by year or powertrain?

Yes, lift range varies. On 2005–2019 diesel models the front lift range is 4–5.5 inches over stock. On 2020–2022 diesel models without the Tremor package it is 4.75–6.25 inches; with Tremor, 3.75–5.25 inches. On 2023–2026 diesel models without Tremor it is 4–5.5 inches; with Tremor, 3–4.5 inches. On 2023–2026 gas models without Tremor it is 4.5–6 inches; with Tremor, 3.5–5 inches. All figures are for a stock-equipped 4WD Crew Cab diesel baseline.

What does the CDCV do and how is it adjusted?

The CDCV (Compression Damping Control Valve) on this coilover kit controls fluid flow under compression and offers 10 distinct external adjustment settings. Turning the knob at the remote reservoir changes the damping character from a softer street tune to a firmer off-road setting without disassembling the shock.

Can I add a secondary shock with this kit?

Secondary shock options are available for this coilover conversion kit. If adding a 2.5 Series or 3.0 Series remote reservoir secondary shock, reservoir doubler kit part number 611003 is also required and is sold separately. Contact ICON for secondary shock compatibility details.

Does installation require any special steps beyond a standard shock swap?

Yes. Installing this coilover conversion kit requires removal of the coil centering cup in the factory coil bucket. After installation, Advanced Driver Assistance Systems (ADAS) must be recalibrated. The kit is a bolt-in design that mounts in the OE coil bucket location, but these two steps are required for proper fitment and safe vehicle operation.
