ICON 57810CP 2.5 Series Rear Shocks with CDC Valve for Toyota 4Runner and FJ Cruiser, 1–3 Inch Lift

ICON Vehicle Specific (V.S.) 2.5 Aluminum Series shocks are designed and built to give your vehicle outstanding performance off-road and a smooth ride on the street. These shocks are configured specifically for each application in both length and damping tune. Like all ICON'S Shock Absorbers, V.S. 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable. For piggyback and specific remote reservoir applications, ICON'S unique use of a 6061 billet aluminum manifold a few inches below the top cap of the shock creates an internal Bump Zone that when used creates an additional 20% of damping force. This additional force helps prevent harsh bottom outs and controls the suspension when compressing at high velocity. The ICON CDC Valve is an externally adjustable valve that restricts oil flow into the reservoir which creates 10 levels of compression damping force ranges. If you are looking for a more user defined tune, consider looking into the Omega Series bypass shocks. ICON VS 2.5 Aluminum Series shocks are designed and built to give your vehicle outstanding performance off-road and a smooth ride on the street. They feature remote reservoirs, damping adjustability, and are 100% rebuildable/revalveable. TECH NOTE: Will not fit models with factory rear air suspension. Vehicles equipped with rear air suspension require rear coil conversion, ICON part number 56110, and rear coil springs, ICON part number 52700 or 52800.

• One piece digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road
• ICON’s internal “Bump Zone” increases damping by 20% to provide more control as the shock approaches full compression
• ICON's CDC Valve technology allows for 10 levels of high-resolution compression adjustability with the turn of a knob
• One-piece impact extruded aluminum cylinders offer excellent corrosion resistance and consistent finish
• Premium grade 5WT shock oil for consistent suspension damping along a wide temperature range
• Remote reservoir design improves heat dissipation to reduce shock fade during prolonged use
• PTFE lined spherical bearings and application specific mounting hardware
• 7/8” diameter induction hardened, chrome plated shock shaft
• Nitrogen charged monotube design with piggyback reservoir
• 6061 aircraft grade aluminum CNC machined components
• 100% Revalveable
• 100% Rebuildable

Upgrade your vehicle’s suspension performance with ICON Part Number 57810CP 2.5 Series rear shocks. Designed for select Toyota 4Runner and FJ Cruiser applications with a 1–3 inch lift, this pair of vehicle-specific shocks is tuned for improved control off-road while maintaining a smooth, comfortable ride on the street. ICON configures each shock’s length and damping specifically for the application, helping deliver predictable handling across varied terrain.
The nitrogen-charged monotube design features remote reservoirs to improve heat dissipation and help reduce shock fade during extended or demanding use. ICON’s externally adjustable CDC Valve provides 10 levels of compression damping adjustment, allowing drivers to fine-tune suspension response with the turn of a knob. A one-piece digressive piston and vehicle-specific valving provide responsive damping, while the internal Bump Zone increases damping force by 20% near full compression to help control high-speed suspension movement and reduce harsh bottoming.
Built for long-term serviceability, these ICON shocks use corrosion-resistant impact-extruded aluminum cylinders, 6061 aircraft-grade aluminum components, premium 5WT shock oil, PTFE-lined spherical bearings, and a 7/8-inch induction-hardened chrome-plated shaft. The shocks are 100% rebuildable and revalveable, making them suitable for drivers who want durable performance and future tuning flexibility. Application-specific mounting hardware is included.
Important fitment note: These shocks will not fit vehicles equipped with factory rear air suspension. Vehicles with rear air suspension require a rear coil conversion using ICON Part Number 56110, along with rear coil springs such as ICON Part Number 52700 or 52800. Verify vehicle configuration and lift height before installation.
