Icon – 2-3.5″ Stage 13 Suspension System Tubular Icon Vehicle Dynamics

The ICON Vehicle Dynamics Stage 13 complete suspension system for the 2022-2023 Toyota Tundra builds upon the Stage 12 system with the addition of billet aluminum adjustable upper and lower rear links. This system offers improved on- and off-road performance with adjustable compression damping, as well as improved alignment specs and increased front-end lift height range for a proper stance and fitment of up to 35″ tires. To compliment the billet aluminum rear links, a 2.5 Series CDEV remote reservoir front coilover shock and billet aluminum front upper control arm combo is included along with a front sway bar drop kit and 2.5 Aluminum Series CDEV rear remote reservoir shocks.

This Stage 13 system features the 2022-2023 Toyota Tundra VS 2.5 Series remote reservoir front coilovers equipped with CDE Valves. These adjustable coilovers allow up to 2-3.5” of lift height adjustability over stock when using the ICON tubular front upper control arms, 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 (up to 40% increase over stock) 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. 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.

The included ICON tubular upper control arm kit is designed to improve the overall performance of the new 2022-2023 Toyota Tundra with corrected front-end geometry, built in additional caster, 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.

Rounding out the Stage 13 suspension system are 2.5 Aluminum Series rear remote reservoir shocks specially tailored for the 2022-2023 Tundra. The 2.5 Aluminum Series shocks’ larger diameter offers outstanding performance off-road and a smooth ride on the street. Remote reservoirs ensure optimum performance by increasing the duration of consistent damping regardless of situation, keeping the shocks at a cooler operating temperature during heavy use. They also feature a unique internal Bump Zone that when used creates an additional 20% of damping force to help better control hard bottom outs. Also equipped with CDE Valves, these offer in vehicle, active compression damping adjustment from soft to hard. Their pairing with the ICON V.S. 2.5 Series CDEV front coilovers results in balanced vehicle control from front to rear and an excellent overall driving experience for your Tundra.
