ICON's 3.0 Series Coilovers with CDEV for 2022-2025 Toyota Tundra and 2023-2025 ToyotaSequoia are designed to take the off-road capability of the truck to new levels by increasing wheel travel by up to 40% and significantly improving the damping ability of the front shocks. 3.0 Series shocks boast 50% more piston surface area in the ride zone of the shock's travel, and 100% in the “Bump Zone”, compared to 2.5 Series shocks. This translates into increased stability and vehicle control at the extremes of off-road use, with benefits also making themselves apparent in on-road driving conditions. The multi-stage hydraulic Bump Zone featured in these 3.0 Series shocks exponentially increases bottom-out resistance as the shock travels through the last 40% of travel, keeping vehicle dynamics in check during those hard hits or unexpected obstacles. ICON's exclusive Compression Damping Electronic Valves are included for actively dialing in your suspension performance. Compression Damping Electronic Valve (CDEV) is an electronically controlled valve that meters the flow of oil to regulate the amount of damping force that is created by the shock when compressed. This infinitely variable valve can react in less than 40ms and has the ability to make extremely precise adjustments for varying terrain. CDEV’s hydraulic circuits are also custom tailored per application to create the highest resolution and dynamic range allowable for each specific vehicle. Powered by ICON Intelligent Control and proprietary ICON mobile app, the system uses information from the onboard G-force sensor and Gyroscope to perform calculations based on algorithms and user-defined settings to predict terrain and adjust shock settings via the CDEV accordingly. These 3.0 Series coilovers are designed as an OEM shock replacement, making installation a simple and straightforward bolt-on affair. Built-in ride height adjustability yields 1.25 to 3.25” of front lift height on Tundra or 3-4.25" of front lift on Sequoia allowing for the fitment of larger, more aggressive wheel and tire combinations. First class ICON manufacturing processes and quality components are used to ensure these shocks function to their maximum potential without issue.
