What is CDEV technology and how does it work?

CDEV stands for Compression Damping Electronic Valve. It's an electronically controlled valve that precisely meters oil flow to adjust damping force as the shock compresses. It can react in less than 40 milliseconds and works with the ICON Intelligent Control system and mobile app, using sensors to predict terrain and adjust settings automatically.

What is the 'Bump Zone' feature?

ICON's internal 'Bump Zone' is a design feature within the shock that adds an additional 20% of damping force as the shock nears its full compression. This helps prevent harsh bottom-outs and provides better control when the suspension is compressing rapidly.

Are these shocks rebuildable or revalveable?

Yes, like all ICON shock absorbers, these VS 2.5 Aluminum Series shocks with CDEV are 100% rebuildable and 100% revalveable. This means you can service them to maintain performance or re-tune them if you change your vehicle setup.

Product Details

Starting with the one-piece, hard anodized, impact-extruded aluminum cylinders, these ICON 2.5 Series rear shocks are built to handle tough conditions while resisting corrosion. They are designed specifically for your 2010-2024 Toyota 4Runner, allowing for a 1 to 3-inch lift in the rear. The nitrogen-charged monotube design, paired with a remote reservoir, helps dissipate heat, reducing the chance of shock fade during extended use, like long off-road trails or demanding terrain.

What really sets these shocks apart is the Compression Damping Electronic Valve (CDEV) technology. This system allows for precise, on-the-fly adjustments to your damping settings, reacting in under 40 milliseconds. It works with the ICON Intelligent Control system, using onboard sensors to predict terrain and automatically adjust the shocks based on your custom settings. For those moments when you’re really pushing the suspension, ICON’s internal “Bump Zone” adds an extra 20% of damping force as the shock nears full compression, helping to prevent harsh bottom-outs and maintain control at high speeds.

These shocks are also fully rebuildable and revalveable, meaning they are a long-term investment in your 4Runner's suspension. They come with PTFE-lined spherical bearings and application-specific mounting hardware to ensure a solid connection. You'll also find 6061 aircraft-grade aluminum components used throughout the build, contributing to both strength and weight savings.
