2003-2007 4Runner FJ 1-3" Rear 2.5 Series Shocks Pair (ICO57810P)

The ICON Vehicle Dynamics V.S. 2.5 Aluminum Series Remote Reservoir (RR) Rear Shocks are a professional-grade suspension upgrade for the 2007-UP Toyota FJ Cruiser and 2003-UP Toyota 4Runner. By utilizing a large 2.5-inch diameter shock body and external remote reservoirs, these shocks offer a massive increase in oil volume and cooling surface area. This design is engineered to handle aggressive off-road driving while preventing shock fade during long stretches of corrugated roads or high-speed desert travel. The integrated internal Bump Zone provides an extra 20% of damping force in the final inches of travel to protect the vehicle from harsh bottom-out impacts during high-velocity compression.

Features

• Remote Reservoir Design: External reservoirs significantly increase oil and nitrogen capacity for maximum heat dissipation and consistent damping performance.
• Internal Bump Zone: A unique 6061 billet aluminum manifold creates an additional damping zone that provides 20% more force at the end of the compression stroke to control bottom-out.
• Application Specific Tuning: Custom-valved by ICON engineers specifically for the weight and suspension geometries of the FJ Cruiser and 4Runner (Gen 4 & Gen 5) platforms.
• 6061-T6 Aluminum Body: One-piece impact-extruded aluminum shock bodies offer superior corrosion resistance and dissipate heat faster than traditional steel.
• Extended Travel: Specifically designed to accommodate rear lift heights of 1 to 3 inches, providing increased articulation for off-road performance.
• Fully Serviceable: 100% rebuildable and revalveable, allowing for long-term maintenance or custom tuning as your vehicle build evolves.
• Heavy Duty Shafts: Features 7/8-inch chrome-plated hardened steel shafts and high-quality redundant seals for maximum durability in harsh environments.

Notes

• Fits 2007-UP Toyota FJ Cruiser and 2003-UP Toyota 4Runner models.
• Compatible with rear lift heights of 1 to 3 inches over stock.
• Sold as a pair (includes both left and right rear shocks).
