ICON 57872XP 2.5 Aluminum Series CDXS Rear Shocks for 2025-2026 Toyota 4Runner, 0-3-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 fully rebuildable and re-tunable. ICON's exclusive Compression Damping Dual Speed (CDXS) valves are included for precisely dialing in your suspension performance. CDXS controls fluid flow under compression, with independent adjustability of high speed and low speed compression force. 10 discreet detented settings for both low and high-speed adjustment knobs allow separate adjustments for handling response and overall aggressiveness. 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. 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.

• 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

Upgrade the suspension performance of your 2025-2026 Toyota 4Runner with the ICON 57872XP Vehicle Specific 2.5 Aluminum Series rear shocks. Designed specifically for applications with up to a 3-inch lift, these shocks combine vehicle-specific valving, remote reservoirs, and ICON’s Compression Damping Dual Speed (CDXS) adjustment system to deliver controlled off-road performance and a smooth, composed ride on pavement. The application-specific length and damping tune help optimize suspension response for the Toyota 4Runner.
The integrated CDXS system provides independent adjustment of high-speed and low-speed compression through 10 detented settings for each adjustment range. This allows you to fine-tune handling response, ride control, and overall suspension aggressiveness for changing terrain or driving preferences. ICON’s internal Bump Zone increases damping by up to 20% as the shock approaches full compression, helping control suspension movement and reduce harsh bottoming during high-velocity compression events.
Built for demanding use, the ICON 57872XP shocks feature a one-piece digressive piston, nitrogen-charged monotube construction, remote reservoirs for improved heat dissipation, and premium 5WT shock oil for consistent damping across a wide temperature range. Hard-anodized, impact-extruded aluminum cylinders resist corrosion, while 6061 aircraft-grade aluminum components, PTFE-lined spherical bearings, application-specific mounting hardware, and a 7/8-inch induction-hardened chrome-plated shaft support long-term durability. A rubber dust boot is included for added shaft protection. These shocks are fully rebuildable and re-tunable for continued service and performance adjustment. Fits 2025-2026 Toyota 4Runner models; lift-height recommendations are based on a stock-equipped vehicle.
