Icon Vehicle Dynamics 91824X 2.5 VS Remote Reservoir CDXS Front Coilover Reservoir Adjustable Shock Lift 3.5-4.5" Ford F-150 Tremor 21-26 Pair

ICON Vehicle Dynamics V.S. Series 2.5" Coilover Shocks

ICON Vehicle Dynamics V.S. Series 2.5" coilover shocks are a front-end upgrade for 2021–2025 Ford F-150 Tremor and other F-150 4WD models equipped with ICON Front Knuckle Kit. They provide increased wheel travel, a taller lift height range, sport-tuned damping on and off road, and improved heat dissipation for sustained off-road performance.

• Application specific length for F-150 Tremor and other F-150 sub-models with ICON Front Knuckle Kit to maximize wheel travel and lift height range.
• Adjustable lift height — 2.5–3" over stock on F-150 Tremor; 3.5–4.5" over stock on other F-150 sub-models (varies by drivetrain and engine).
• Vehicle-specific valving for superior shock damping and control on varied terrain.
• 2.5" shock body and increased piston area for improved damping and ride characteristics compared to stock.
• Remote reservoirs to increase oil volume and heat dissipation, resisting overheating and cavitation under hard use.
• ICON Compression Damping Dual Speed (CDXS) with independent low-speed and high-speed compression adjustability; 10 detented settings on each knob for fine tuning handling response and aggressiveness.
• ICON-engineered coil springs matched to the damper characteristics.
• 6061 aircraft-grade aluminum CNC machined components with corrosion-resistant CAD-plated shock body and 7/8" shaft.
• FK rod end bearings for extended longevity and minimal deflection.
• High-strength alloy CNC machined lower bar pin for durable mounting.
• 100% bolt-on installation — no drilling, cutting, or welding required.
• Serviceable design — shocks are fully serviceable for long-term maintenance.

Notes

• Factory wheels and tires fitment: Not compatible with all available OE wheel/tire combinations; aftermarket wheels with lower offset/less backspace are recommended.
• Recommended wheel sizes (examples): 17x8.5" with 5.0" backspace / 6mm offset; 18x9" with 5.25" backspace / 6mm offset; 20x9" with 5.625" backspace / 16mm offset.
• Recommended tire example: 34" x 12.50". Larger tires may fit but fender trimming and modifications may be required.
• Only fits 4WD models.
• Will not work with factory-installed electronically controlled suspension.
• ICON Delta Joint Pro upper control arms are required for compatibility where specified.
• Requires recalibration of Advanced Driver Assistance Systems (ADAS) after installation.
• All F-150 submodels except Tremor also require ICON Front Knuckle Kit for compatibility.
• Will not fit F-150 Raptor.
• Lift height ranges by model/engine:
  • F-150 Tremor: 2.5–3" over stock.
  • Models with gasoline/flex fuel engines: 3.5–4.5" over stock.
  • Models with PowerBoost hybrid engines: 3.25–4.25" over stock.
  • Models with Power‑Stroke diesel engines: 3–4" over stock.
• Lift heights indicated apply to stock-equipped vehicles.
