The ICON CDE Valve upgrade is included for those desiring an easy way to tune the ride electronically from inside the vehicle. 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. When paired with ICON 2.5 or 3.0 Series CDEV rear shocks vehicle control will be balanced front to rear, resulting in the best overall driving experience for your Toyota Sequoia TRD Pro.. ICON Vehicle Dynamics V.S. 2.5 Series remote reservoir CDEV front coilover shocks are an incredible upgrade for the front end of the 2023-2025 Toyota Sequoia TRD Pro. These adjustable coilovers allow up to 1-2.5” of lift height adjustability on Sequoia TRD Pro, allowing the use of larger, more aggressive wheel and tire combinations. ICON’s Vehicle-specific shock length and valving along with the larger 2.5” shock body and increased piston area over stock components yield the maximum travel possible along with superior ride quality and suspension performance both on- and off-road. Remote reservoirs greatly increase shock oil volume and heat dissipation surface area to resist overheating and cavitation under hard use, which can lead to damper fade. ICON's exclusive Compression Damping Control Valves are included for precisely dialing in your suspension performance. Additionally, their vehicle specific shock length allows the stock, billet TRD front upper control arms to be utilized with the new suspension system, eliminating the requirement for ICON front UCAs.. ICON’s Vehicle-specific shock length and valving along with the larger 2.5” shock body and increased piston area over stock yield the maximum travel possible along with superior ride quality and suspension performance both on- and off-road.. APPLICATION NOTE #189: For Sequoia TRD Pro ICON Diff Drop (part# 55156) is recommended but not required. If installing ICON Diff Drop, ICON Skid Plate Spacer Kit (part# 55164) is also required.. APPLICATION NOTE #85: Advertised lift height ranges are for a stock equipped vehicle. Increasing weight of vehicle due to accessories will alter lift range..
