Product Description

ICON 2017-2019 Ford F250/F350, 4.5" Lift, Stage 2 Suspension System (K64512)

The ICON Vehicle Dynamics Stage 2 Suspension System is a complete performance upgrade engineered for 2017–2019 Ford F-250 and F-350 Super Duty 4WD trucks. Designed to dramatically improve ride quality, stability, and off-road capability, this system features ICON 2.5 Aluminum Series shocks, dual-rate coil springs, and precision-engineered geometry correction components. The result is a balanced suspension solution ideal for towing, daily driving, job-site work, and off-road adventures.

4.5” Lift Height for Increased Ground Clearance

This system delivers approximately 4.5” of front lift using ICON-engineered dual-rate coil springs, providing improved tire clearance and enhanced ground clearance. The increased ride height allows fitment of larger wheel and tire combinations while maintaining predictable handling characteristics.

2.5 Series Aluminum Shocks for Improved Ride Quality

ICON 2.5 Aluminum Series front shocks with internal reservoirs and rear piggyback reservoir shocks provide vehicle-specific valving for superior damping control. The increased oil capacity improves heat dissipation, delivering consistent performance across demanding driving conditions. 

Dual-Rate Coil Springs for Balanced Performance

The included dual-rate front coil springs are designed to improve ride comfort while maintaining stability under load. This spring design helps deliver consistent handling on highways, rough terrain, and towing applications.

Radius Arm Drop Brackets for Corrected Suspension Geometry

Heavy-duty radius arm drop brackets restore proper caster angles after lifting, improving steering feel and alignment stability. This ensures consistent handling characteristics and reduces premature component wear.

Adjustable Front Track Bar for Proper Axle Alignment

An adjustable front track bar helps maintain proper axle centering after installation, improving steering precision and minimizing suspension deflection during aggressive driving or heavy-duty use.

Rear Block Kit and U-Bolts for Load Stability

A heavy-duty rear block kit with new U-bolts provides rear lift and improved load stability. This component enhances towing capability while maintaining rear suspension strength and reliability.

Engineered for Increased Wheel Travel and Durability

This Stage 2 system increases front wheel travel by approximately 50% over stock, improving suspension articulation and off-road capability. Durable FK rod end bearings and corrosion-resistant shock bodies ensure long-term reliability in demanding environments.
