ICON K64538RL 4.5-Inch Stage 8 Suspension System for 2023 Ford F250/F350

Upgrade your 2023 Ford F250 or F350 Super Duty with the comprehensive ICON Stage 8 system, delivering controlled 4.5-inch lift through high-performance X2.5 valved shocks and precision-engineered X-Series radius arms that restore factory geometry.

• Precision Geometry Correction: Replaces worn or lifted OEM front mounts with extended X-series radius arms to recalibrate caster and camber, eliminating steering wander and ensuring accurate alignment after installation.
• X2.5 Monotube Shock Engineering: Front and rear shocks feature a 2.5-inch internal piston diameter with dual-stage ICV (Internal Competition Valves) to seamlessly transition between soft off-road articulation and stable highway load-bearing performance.
• Advanced Thermal Management: Integrated oil expansion packs within the reservoir assemblies absorb heat dissipation during extended rock crawling or towing, significantly reducing fluid degradation and maintaining consistent damping over time.
• Durable Material Construction: Reservoir bodies and perches are machined from T6061-T6 billet aluminum to reduce unsprung weight without sacrificing strength, while hard-anodized finishes protect against corrosion in harsh environments.
• Optimized Clearance & Fitment: Designed specifically for the 2023 platform lift requirements, the geometry supports tires up to 37 inches while maintaining proper track width; fits both 4x4 and 4x2 configurations where applicable.
• Complete Hardware Suite: Includes all necessary high-grade mounting bolts, spacers, and installation hardware required for assembly, minimizing additional part sourcing and streamlining the build process.
• Warranty Backing: Supported by ICON Vehicle Dynamics manufacturer warranty coverage, reflecting confidence in long-term reliability and material integrity for daily drivers and trail rigs alike.

This system addresses the common drawbacks of budget lifts by actively compensating for altered suspension leverage ratios. By integrating corrected radius arms with progressive shock valving, the package prevents premature wear on tie rods and ball joints associated with aggressive lift heights. Whether navigating rocky terrain or hauling heavy payloads, the tuned compression and rebound characteristics keep the chassis planted and protect drivetrain components from vibration-induced fatigue.
