ICON V.S. 2.5 Series Front Coilovers Remote Reservoir for 2021-2026 Ford F-150 4WD and Tremor

The ICON Vehicle Dynamics V.S. 2.5 Series Front Coilovers with Remote Reservoir are a bolt-on front suspension upgrade for 2021–2026 Ford F-150 4WD and Tremor trucks, sold as a pair. Lift height range varies by powertrain: 3.5–4.5" on gasoline/flex-fuel models, 3.25–4.25" on PowerBoost hybrid, 3–4" on Power-Stroke diesel, and 2.5–3" on the Tremor. ICON Delta Joint Pro Upper Control Arms and, on all non-Tremor F-150 sub-models, the ICON Front Knuckle Kit (part 94000) are required for installation.

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.

More Wheel Travel Without Compromise

The application-specific coilover length for the F-150 Tremor and other F-150 sub-models equipped with the ICON Front Knuckle Kit is engineered to maximize wheel travel within the factory envelope. More travel means the suspension can absorb larger obstacles (washboard, rock ledges, sudden drop-offs) without the wheel losing contact with the ground, which translates directly to traction and steering control on uneven terrain.

A 2.5" Shock Body Built to Resist Fade

The 2.5" shock body provides greater piston area than stock components, improving damping force across a wider range of shaft speeds. Remote reservoirs extend that advantage by increasing shock oil volume and heat-dissipation surface area, so the damper resists cavitation and fade during sustained off-road use. The shock body is corrosion-resistant CAD-plated, and the 7/8" shaft runs FK rod end bearings for longevity and minimal deflection under load.

Vehicle-Specific Valving, Fully Serviceable

ICON tunes the valving for each application rather than using a universal map, producing a sport-oriented damping character that works on pavement and off-road without requiring a separate mode switch. The V.S. 2.5 Series coilovers are fully serviceable, so worn seals or a revalve for a different use case can be addressed without replacing the entire unit. CNC-machined 6061 aircraft-grade aluminum components and a high-strength alloy lower bar pin complete the assembly.

Features

• Application-specific length: engineered for F-150 Tremor or F-150 4WD sub-models with ICON Front Knuckle Kit to maximize wheel travel
• Remote reservoir: increases oil volume and heat-dissipation area to resist fade and cavitation under hard use
• 2.5" shock body: larger piston area than stock for improved damping ability across terrain types
• Vehicle-specific valving: sport-tuned damping character calibrated for the F-150 platform
• 6061 aluminum CNC components: CAD-plated shock body, 7/8" shaft, FK rod end bearings, high-strength alloy lower bar pin
• Fully serviceable: shocks can be rebuilt or revalved without full replacement
• 100% bolt-on: no drilling, cutting, or welding required for installation

Specifications

Who This Is For and Isn't

These coilovers suit 2021–2026 Ford F-150 4WD and Tremor owners who want increased front lift, more wheel travel, and improved damping for off-road use, and who are prepared to install the required ICON Front Knuckle Kit (non-Tremor sub-models) and ICON Delta Joint Pro Upper Control Arms as part of the same build.

These coilovers do not fit the F-150 Raptor, any 2WD F-150, or any F-150 equipped with factory electronically controlled suspension. They are not compatible with all OE wheel and tire combinations; aftermarket wheels with lower offset and less backspace are recommended. ADAS recalibration is required after installation.

Common Questions

Do these coilovers fit the F-150 Raptor?

The ICON V.S. 2.5 Series Front Coilovers (SKU 91824) do not fit the F-150 Raptor. Fitment is limited to 2021–2026 Ford F-150 4WD and Tremor sub-models only.

What additional parts are required for installation?

All F-150 sub-models except the Tremor require the ICON Front Knuckle Kit (part 94000) in addition to these coilovers. All fitments, including the Tremor, require ICON Delta Joint Pro Upper Control Arms. ADAS recalibration is also required after installation on any equipped vehicle.

How much lift do these coilovers provide?

Lift range depends on powertrain. The F-150 Tremor achieves 2.5–3" over stock. Gasoline and flex-fuel models achieve 3.5–4.5". PowerBoost hybrid models achieve 3.25–4.25". Power-Stroke diesel models achieve 3–4". All figures are for a stock-equipped vehicle before installation.

Will these work with factory electronic suspension?

No. The ICON V.S. 2.5 Series Front Coilovers are not compatible with factory-installed electronically controlled suspension. Verify your F-150's suspension configuration before ordering.

Can the shocks be rebuilt or revalved later?

Yes. The V.S. 2.5 Series coilovers are fully serviceable, so seals can be replaced and valving can be adjusted without purchasing a new unit.
