Icon 23 Sequoia 3-4.25" Stage 4 3.0 Suspension System Billet - K53254
The ICON Vehicle Dynamics Stage 4 3.0 complete suspension system for the 2023 Toyota Sequoia builds upon the Stage 12 2.5 suspension system with the upgrade to 3.0 Series CDEV front coilovers. This system offers improved on- and off-road performance, with active electronic shock damping adjustment, as well as improved alignment specs, improved rear articulation, and increased front-end lift height range for a proper stance and fitment of up to 35" tires.
This Stage 4 system features the 2023 Toyota Sequoia VS 3.0 Series remote reservoir front coilovers equipped with CDE Valves. These adjustable coilovers allow up to 3-4.25” of lift height adjustability over stock when using the ICON billet front upper control arms, allowing the use of larger, more aggressive wheel and tire combinations. The larger 3.0 Series shocks offer 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. The multi-stage hydraulic Bump Zone 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. Focus on driving and let ICON Intelligent Control (IIC) read the terrain and make near-instant adjustments via the Compression Damping Electronic Valve (CDEV) at each individual shock. Control the system wirelessly through the IIC app on your phone and once configured the system functions without driver input. Additionally, ICON’s Vehicle-specific shock length yields the maximum travel possible (up to 40% increase over stock), all translating 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 included ICON billet aluminum upper control arm kit is designed to improve the overall performance of the new 2023 Toyota Sequoia with corrected front-end geometry, increased on-vehicle camber and caster adjustment, and improved suspension component clearance. Additionally, replacing the OE ball joint with the all-new, serviceable, and rebuildable ICON Delta Joint PRO allows for full bump and droop travel of the front suspension while eliminating bind.
The included sway bar drop brackets help minimize sway bar link bind through the suspension travel range. This helps the suspension move more freely and allows for the full range of wheel travel without overstressing any OE components.
ICON billet aluminum adjustable rear upper and lower links are made from CNC machined 6061 aluminum and anodized for corrosion resistance. These link arm kits feature PTFE-lined FK rod ends for increased suspension articulation, reduced deflection, and on-vehicle link arm length adjustability using ICON’s double adjuster system. Additionally, multi durometer bushings are installed that allow for noise free operation and maximum angularity without the need for periodic greasing and/or other maintenance.
The dual-rate rear coil design provides a softer ride height spring rate with a firmer overload rate that combine to deliver on-road comfort with excellent bottoming resistance and superior off-road performance. 3” of rear lift height over stock allows a for level stance front to rear.
The ICON Billet Rear Adjustable Track Bar helps center the axle of your lifted 2023 Sequoia. Double adjuster rod end threads allow easy “on-vehicle” fine adjustment of track bar length without requiring removal or disassembly of the track bar. The track bar is CNC machined from solid 6061 aluminum bar, and anodized to match the look of ICON's billet upper and lower links.
Rounding out the Stage 4 suspension system are 3.0 Series rear remote reservoir shocks specially tailored for the 2023 Sequoia. 3.0 Series shocks boast 50% more piston surface area compared to 2.5 Series shocks, offering outstanding performance off-road and a smooth ride on the street. Increased internal oil volume and more external surface area compared to 2.5 Series Shocks, plus their remote reservoirs, offer even greater heat dissipation and resistance to shock fade under hard use. Also equipped with CDE Valves, these offer active, on the fly compression damping adjustment from soft to hard. Their pairing with the ICON V.S. 3.0 Series CDEV front coilovers results in balanced vehicle control from front to rear and an excellent overall driving experience for your Sequoia.

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.
