ICON 20-22 Ford F-250/F-350 2.5-Inch Stage 1 Suspension System with Expansion Pack Technology

Elevate Performance and Precision on 4WD Ford Super Duty Platforms

The ICON K62521L Stage 1 Suspension System delivers controlled elevation and refined ride dynamics for 2020–2022 Ford F-250 and F-350 Super Duty 4WD pickups, featuring a calibrated 2.5-inch lift profile backed by advanced Expansion Pack shock technology. By incorporating dual-circuit damper tubes, the system lets owners independently tune spring progressivity to manage payload shifts, balancing daily drivability with serious off-road capability. The setup lifts ride height sufficiently to clear 35-inch tires directly, with room for 37-inch combinations subject to minor fender modification, ensuring aggressive styling without compromising steering response or braking clearance.

• Restricted 4WD Compatibility: Validated strictly for 4WD Ford F-250 and F-350 units; explicitly excludes F-450 cab-and-chassis applications, non-4WD variants, and all 2024 model year vehicles.
• Independent Rate Adjustment: Expansion Pack architecture enables manual setting of compression stages, smoothing out small bumps while maintaining robust bottom-out protection under dynamic loads.
• Tremor Package Lift Variance: Vehicles loaded with the manufacturer Tremor package receive a targeted 1.5-inch lift above the Tremor's modified factory height, preserving intended component geometry.
• Driveshaft and Axle Management: Re-raising the chassis alters steering arc and pinion angles; installation guidelines confirm that an adjustable track bar is typically necessary to realign the axle centrally and maximize joint life.
• Wheel Specification Optimization: Designed to pair with aftermarket wheels requiring 5.25-inch backspacing or 6-millimeter offset, maintaining proper scrub radius and preventing interference with strut or control arm envelopes.
• SRW Brake Line Requirement: Single rear wheel builds require supplementary long brake lines (matching part number 61111 context) to extend fluid reach and avoid line tension or failure at full droop.
• Compact Shipping Profile: Arrives in a consolidated package measuring 27.0-inches by 12.0-inches by 6.0-inches, weighing 81 pounds gross, streamlining warehouse handling and freight estimates.

Safety and Technical Considerations

California Residents: WARNING - This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.

Mounting torque values must meet OEM specifications, and hardware inspection is recommended after the initial break-in period. Verify tire clearance with chosen wheel offsets before operation, and ensure brake systems are bled and functional following the integration of any required line extensions.
