ICON Vehicle Dynamics K93013 Stage Suspension System with Billet UCA Lift - 4 1.75-2.63

The ICON Vehicle Dynamics K93013 is a complete Stage 4 suspension lift system engineered for 2009–2013 Ford F-150 2WD trucks seeking maximum on- and off-road performance. ICON's engineering philosophy centers on increasing wheel travel and damping ability, delivering outstanding vehicle control and ride quality in virtually any driving condition — without sacrificing towing capacity.

At the heart of this system are vehicle-specific tuned 2.5" coilover shocks featuring external remote reservoirs equipped with ICON's Continuous Damping Control Valve (CDCV) for exceptional heat dissipation and consistent damping performance. Paired with ICON-engineered Eibach coil springs, these coilovers are height adjustable from 1.75" to 2.63" of lift over stock, providing the clearance needed to run larger, more aggressive wheel and tire combinations.

The rear of the system is handled by ICON 2.5 Aluminum Series Piggyback rear shocks with CDCV, utilizing vehicle-specific valving to balance front-to-rear performance. The external reservoir design maintains cooler operating temperatures during extended or heavy use, ensuring consistent damping throughout. ICON's CDC Valve system provides 10 externally adjustable compression damping settings, from soft to firm, making it easy to tune the ride on the fly without tools.

Billet Upper Control Arms with Patented Delta Joint are a standout feature of the K93013. Precision CNC-machined from 6061 aircraft-grade billet aluminum, these UCAs increase strength and durability while restoring factory alignment spec range and increasing caster over stock. ICON's patented Delta Joint replaces the conventional uniball with a heavy-duty, high-angle ball joint that combines the articulation performance of a uniball with the weather protection of a traditional ball joint. Key Delta Joint advantages include:

• Zinc-plated housing for corrosion resistance
• Grease seal keeps contaminants away from internal components
• Greasable, metal-on-metal construction for long service life
• Noise-free operation under daily driving and off-road conditions
• Greater angularity than a standard ball joint; more durability than a standard uniball
