The ICON Vehicle Dynamics V.S. 2.5 Series Internal Reservoir (IR) Front Coilover Kit is a premier suspension upgrade for the 2010-UP Toyota 4Runner, 2010-2014 Toyota FJ Cruiser, and 2010-2023 Lexus GX460. These adjustable coilovers are designed to replace the small-diameter factory struts with a heavy-duty 2.5-inch shock body, providing a massive increase in piston surface area and oil volume. This results in superior damping control and heat dissipation, ensuring a smooth, controlled ride on the highway and high-performance handling on the trails. The threaded shock bodies allow for adjustable lift height, enabling you to level your vehicle and accommodate larger, more aggressive wheel and tire combinations.

Features

• Adjustable Lift Height: Threaded shock bodies provide 0 to 3.5 inches of front lift height adjustment, allowing for a leveled stance and increased tire clearance.
• 2.5 Series Shock Body: The large diameter body increases oil capacity to dissipate heat effectively, preventing shock fade during aggressive off-road use.
• Internal Reservoir (IR): A self-contained design that houses the nitrogen charge internally, offering a clean, bolt-on installation without the need for mounting external reservoirs.
• Application Specific Valving: Custom-tuned by ICON engineers specifically for the weight and suspension geometry of the late-model 4Runner, FJ Cruiser, and GX460 platforms.
• OE Control Arm Compatible: These coilovers are engineered to provide maximum travel while remaining compatible with the vehicle’s stock front upper control arms.
• Premium Construction: Built with 7/8-inch chrome-plated hardened steel shafts and CNC-machined 6061 aluminum components for professional-grade durability.
• Fully Serviceable: These shocks are 100% rebuildable and re-tunable, ensuring they can be maintained for the life of the vehicle.

Notes

• Fits 2010-2024 Toyota 4Runner (2WD/4WD), 2010-2014 Toyota FJ Cruiser, and 2010-2023 Lexus GX460.
