ICON 2023-2025 Ford F-250/F-350 Super Duty 4WD, Diesel, 2.5" Lift, Stage 5 Suspension System w/ Radius Arms (K65894R)
The ICON Vehicle Dynamics Stage 5 Suspension System with Radius Arms is a premium suspension upgrade engineered specifically for 2023–2025 Ford F-250 and F-350 Super Duty 4WD diesel trucks. Designed to deliver superior ride quality, enhanced off-road capability, and improved towing stability, this system features 2.5 Series CDCV remote reservoir front coilovers, fabricated radius arms, dual steering stabilizers, and matched rear piggyback reservoir shocks. With adjustable compression damping and precision-engineered components, this system offers outstanding control and durability for heavy-duty applications and demanding terrain.
2.5” Front Lift for Improved Clearance and Performance
This system provides approximately 2.5 inches of front lift using ICON-engineered dual-rate coil springs optimized for diesel-powered Super Duty trucks. The added ride height improves ground clearance and allows for larger tire fitment while maintaining stable suspension geometry.
2.5 Series CDCV Remote Reservoir Coilovers
Front ICON 2.5 Series coilovers feature remote reservoirs and Compression Damping Control Valve (CDCV) technology, providing 10 levels of external compression adjustment. This allows drivers to quickly tune suspension firmness for highway comfort, towing loads, or off-road performance.
Fabricated Radius Arms for Strength and Geometry Correction
The included fabricated radius arms feature a fully boxed design with sealed pivot bushings to reduce road feedback and improve long-term durability. Their optimized profile also increases tire clearance at full steering lock, supporting larger tire sizes without interference.
Rear Piggyback Reservoir Shocks
ICON 2.5 Aluminum Series piggyback rear shocks increase oil capacity and cooling efficiency, delivering consistent damping performance under load. This setup improves ride stability, reduces shock fade, and enhances overall vehicle control across rough terrain.
Dual Steering Stabilizer System
A dual steering stabilizer kit helps reduce steering feedback and vibration, improving handling stability when running larger tires or driving across uneven terrain. This system enhances driver confidence and steering precision under demanding conditions.
Adjustable Track Bar for Proper Axle Alignment
An adjustable front track bar ensures proper axle positioning after installation, maintaining correct steering geometry and improving overall vehicle handling. This component supports long-term alignment accuracy and suspension performance.
Vehicle-Specific Shock Tuning
All shocks in the Stage 5 system are tuned specifically for the 2023–2025 Super Duty platform. This tuning improves ride comfort, increases suspension control, and enhances overall vehicle stability during both daily driving and heavy-duty operation.
Built for Heavy-Duty Applications
This Stage 5 system is designed for trucks used in towing, job site work, and off-road driving. With increased wheel travel and improved damping control, it provides dependable performance while maintaining factory towing capability and durability.
