ICON 57872P 2.5 VS Aluminum Series Rear Remote Reservoir Shock for 2025-2026 Toyota 4Runner

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 fully rebuildable and re-tunable. 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. If you are looking for a more user defined tune, consider ICON compression adjustable shock absorbers equipped with CDCV, CDXS, or CDEV. ICON 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. They feature remote reservoirs and are 100% rebuildable/revalveable. APPLICATION NOTE #55: Shocks are fully serviceable. Lift heights indicated are for a stock equipped vehicle.

• One-piece digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road
• All ICON 2.5 Aluminum Series Remote Reservoir shocks can be upgraded with an ICON compression adjuster (CDCV, CDXS, or CDEV)
• ICON’s internal “Bump Zone” increases damping by 20% to provide more control as the shock approaches full compression
• One-piece, hard anodized, 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 remote reservoir
• Rubber dust boot included for added shaft protection
• 6061 aircraft grade aluminum CNC machined components
• Fully rebuildable and re-tunable

The ICON 57872P 2.5 VS Aluminum Series rear remote reservoir shock is engineered specifically for the 2025-2026 Toyota 4Runner with 0–3 inches of lift. Its vehicle-specific length and damping calibration deliver controlled suspension performance off-road while maintaining a smooth, composed ride on the street. The nitrogen-charged monotube design and remote reservoir improve heat dissipation, helping reduce shock fade during extended or demanding driving conditions.
The shock features a one-piece digressive piston with application-specific valving for predictable control across varied terrain. ICON’s internal Bump Zone can increase damping force by 20% as the shock approaches full compression, helping manage high-speed suspension movement and reduce harsh bottom-outs. The remote reservoir platform can also be upgraded with an ICON CDCV, CDXS, or CDEV compression adjuster for a more customized suspension tune.
Built for long-term serviceability, the ICON 57872P uses a hard-anodized, impact-extruded aluminum cylinder, CNC-machined 6061 aircraft-grade aluminum components, a 7/8-inch induction-hardened chrome-plated shaft, PTFE-lined spherical bearings, and application-specific mounting hardware. Premium-grade 5WT shock oil supports consistent damping across a broad temperature range, while the included rubber dust boot helps protect the shaft from contamination. This shock is fully rebuildable and re-tunable. Lift-height applications are based on a stock-equipped vehicle; refer to the manufacturer’s application guidance before installation.
