ICON V.S. 2.5 Series Front Coilover Kit for 2009-2013 Ford F-150 4WD with Fabtech 6" Lift

The ICON V.S. 2.5 Series Front Coilover Kit (SKU 91701-CB) is a full-length, internal-reservoir coilover system engineered for 2009–2013 Ford F-150 4WD trucks running a Fabtech 6" subframe lift kit. The 2.5" shock body, vehicle-specific valving, and adjustable ride height deliver tuned damping performance on pavement and off-road without the coilover spacers that shorter, factory-length units require at this lift height.

Full-Length Design Eliminates Spacer Stacking

Factory-length coilovers paired with a 6" lift typically require top-load spacers to make up the height difference, a compromise that reduces usable shock travel and can introduce harshness. The ICON V.S. 2.5 Series kit is dimensioned specifically for the Fabtech 6" lift geometry, so the coilover fills the full available stroke without a spacer. That means more wheel travel is available for absorbing terrain, and the shock operates across the range it was valved for rather than a shortened portion of it.

2.5" Shock Body for Improved Damping

The larger 2.5" shock body provides greater piston area than stock components, which increases the damping force the shock can generate and sustain across repeated hits. Vehicle-specific valving, tuned for the F-150's weight and suspension geometry at this lift height, delivers a sport-oriented feel without sacrificing compliance on rough terrain. The internal reservoir extends fluid capacity, helping the shock resist fade on sustained off-road runs where a standard shock would heat-cycle and lose consistency.

Bolt-On Installation, Durable Construction

The kit installs without drilling, cutting, or welding. CNC-machined 6061 aircraft-grade aluminum components keep unsprung weight in check, while CAD-plated shock bodies and 7/8" hardened chrome shafts resist corrosion in mud, water, and road-salt environments. FK rod end bearings reduce deflection under load and are rated for extended service life compared to standard rubber bushings. Ride height is adjustable via the coilover perch, allowing fine-tuning to the driver's preference or payload.

Features

Who This Is For and Isn't

This kit suits 2009–2013 Ford F-150 4WD owners who have installed or are installing a Fabtech 6" subframe lift and want a full-length front coilover with tuned damping, adjustable ride height, and bolt-on fitment with no fabrication required.

This kit is not designed for F-150 trucks without a 6" lift, for two-wheel-drive F-150 variants, or for model years outside 2009–2013. It covers front suspension only; pairing with compatible ICON rear shocks is required for balanced front-to-rear damping. Compatibility with non-Fabtech 6" lift kits is unconfirmed for this SKU.

Common Questions

Does this kit work with lift kits other than the Fabtech 6" system?

The ICON V.S. 2.5 Series front coilover kit (SKU 91701-CB) is optimized for the Fabtech 6" lift and may be compatible with other 6" lift kits, but compatibility beyond the Fabtech application is unconfirmed for this SKU. Verify fitment with your lift kit's documentation before ordering.

What rear shocks pair with this front coilover kit?

ICON recommends pairing this front coilover kit with ICON's 2.0 Aluminum Series or 2.5 Series rear shocks for the 2009–2013 Ford F-150 4WD. Running matched front and rear ICON dampers balances vehicle control across both axles for the best overall driving experience.

Is any cutting, welding, or drilling required to install this kit?

No. The ICON V.S. 2.5 Series front coilover kit is a 100% bolt-on system for 2009–2013 Ford F-150 4WD trucks with a Fabtech 6" lift. No drilling, cutting, or welding is required for installation.

Why does this kit not need coilover spacers when other coilovers do?

Factory-length coilovers are too short for a 6" lift and require top-load spacers to compensate. The ICON V.S. 2.5 Series kit is full-length, engineered to the correct dimensions for the Fabtech 6" lift geometry, so the shock operates across its full designed travel without a spacer stack reducing available stroke.
