Icon Vehicle Dynamics 91723 2.5 VS Internal Reservoir Front Coilover 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 engineered for 2021–2025 Ford F-150 Tremor and other F-150 4WD models equipped with ICON Front Knuckle Kit. They deliver increased wheel travel, improved damping, and a taller lift range to accommodate larger, more aggressive wheel and tire combinations while maintaining on- and off-road ride quality.

• Application specific length: Designed for F-150 Tremor and other F-150 sub-models with ICON Front Knuckle Kit to maximize wheel travel and lift height.
• Adjustable lift height: 2.5–3" over stock on F-150 Tremor; 3.5–4.5" over stock on other F-150 sub-models with ICON Front Knuckle Kit (see notes for engine-specific ranges).
• Vehicle-specific valving: Sport-tuned damping for predictable control on- and off-road.
• 2.5" shock body: Larger body and increased piston area provide improved damping and ride characteristics versus stock.
• Internal nitrogen reservoir: Ensures consistent performance under hard use.
• ICON engineered coil springs for optimized spring rates and performance.
• Premium construction: 6061 aircraft-grade aluminum CNC-machined components and corrosion-resistant CAD-plated shock body with 7/8" shaft.
• Durability and precision: FK rod-end bearings for extended longevity and minimal deflection; high-strength alloy CNC-machined lower bar pin.
• Serviceable: Shocks are fully serviceable.
• 100% bolt-on installation: No drilling, cutting, or welding necessary.
• Rear pairing: Pair with ICON rear 2.0 Aluminum Series or 2.5 Aluminum Series shocks for balanced front-to-rear vehicle control.
