ICON V.S. 2.5 Series Front Coilover Kit for 2004-2008 Ford F-150 2WD with Fabtech 6" Lift

The ICON V.S. 2.5 Series Front Coilover Kit (SKU 91501-CB) is a bolt-on front suspension upgrade for 2004–2008 Ford F-150 2WD trucks already equipped with a Fabtech 6" subframe lift kit, featuring a 2.5" shock body with internal reservoir and vehicle-specific valving for tuned on- and off-road damping.

Full-Length Design Eliminates Coilover Spacers

Standard-length coilovers paired with a 6" lift typically require top-load spacers to reach the correct ride height, a compromise that reduces available shock travel and can introduce unwanted geometry changes. The ICON V.S. 2.5 Series coilovers are length-optimized specifically for the Fabtech 6" lift subframe, so they fill the full shock mount span without spacers. The result is more usable wheel travel and a cleaner, more predictable suspension geometry at the lifted ride height.

2.5" Shock Body with Vehicle-Specific Valving

The larger 2.5" shock body provides increased piston area compared to stock components, improving damping force and consistency across varying terrain: highway on-ramps, rutted dirt roads, and everything between. ICON's vehicle-specific valving is calibrated for the F-150 2WD platform, delivering a sport-tuned response without sacrificing everyday ride quality. The internal reservoir extends the oil volume available to the shock, helping maintain consistent damping during repeated compression cycles on longer off-road runs.

Adjustable Ride Height and Durable Hardware

Ride height is adjustable via the coilover perch, allowing fine-tuning after installation without removing the shock. The shock body is CAD-plated for corrosion resistance, shafts are 7/8" hardened chrome, and structural components are CNC-machined from 6061 aircraft-grade aluminum. FK rod end bearings are used at the mounting points for longevity and minimal deflection under load. Installation is 100% bolt-on, with no drilling, cutting, or welding required.

Specifications

Who This Is For and Isn't

This coilover kit suits owners of 2004–2008 Ford F-150 2WD trucks who have already installed a Fabtech 6" subframe lift and want a front shock upgrade with improved damping, adjustable ride height, and a full-length design that avoids the compromises of spacer-based setups.

This kit does not fit 4WD F-150 variants, F-150 model years outside 2004–2008, or trucks without a Fabtech 6" subframe lift already installed. Rear shocks are not included and must be purchased separately. These coilovers are optimized for the Fabtech 6" lift; compatibility with other lift brands or heights is not confirmed for this SKU.

Common Questions

Do these coilovers require a lift kit to be installed first?

Yes. The ICON V.S. 2.5 Series front coilover kit (SKU 91501-CB) is length-optimized for use with a Fabtech 6" subframe lift kit already installed on a 2004–2008 Ford F-150 2WD. Installing these coilovers without the corresponding lift subframe will result in incorrect geometry and ride height.

Are rear shocks included in this kit?

No. This kit covers the front coilovers only. ICON recommends pairing these with ICON 2.0 Aluminum Series or 2.5 Series rear shocks to balance vehicle control front to rear, but those rear shocks are sold separately.

Is any cutting, welding, or drilling required for installation?

No. The ICON V.S. 2.5 Series front coilover kit is a 100% bolt-on installation for 2004–2008 Ford F-150 2WD trucks equipped with the Fabtech 6" lift. No cutting, welding, or drilling is required.

Can ride height be adjusted after installation?

Yes. The ICON V.S. 2.5 Series coilovers feature an adjustable perch that allows ride height fine-tuning after the kit is installed on the vehicle, without requiring removal of the shock assembly.
