ICON V.S. 2.5 Aluminum Piggyback Rear Shocks with CDEV for 2014-2026 Ram 2500

The ICON V.S. 2.5 Aluminum Series Piggyback Rear Shocks with CDEV are vehicle-specific shock absorbers engineered for the 2014–2026 Ram 2500, tuned in both length and damping for this application. Two fitment windows apply: 0–1" rear lift on Ram 2500 trucks equipped with rear coil springs, and 3" rear lift on Ram 2500 trucks equipped with factory rear air springs. Sold as a pair.

Bump Zone Control at High Velocity

A 6061-billet aluminum manifold positioned just below the top cap creates an internal Bump Zone that adds 20% damping force as the shock approaches full compression. That extra resistance controls the energy spike that causes harsh bottom-outs on rough terrain, keeping the suspension composed during high-speed washboard, sudden ledge drops, or loaded towing over broken pavement. The one-piece digressive piston uses vehicle-specific valving to balance that off-road control with a compliant street ride.

Electronic Compression Damping from Inside the Cab

The Compression Damping Electronic Valve (CDEV) is an infinitely variable electronic valve that adjusts compression damping in less than 40 milliseconds. Powered by the ICON Intelligent Control (IIC) system and the ICON mobile app, it reads an onboard G-force sensor and gyroscope to predict terrain changes and update shock settings automatically based on user-defined algorithms. The result is active damping that responds faster than a driver can react, without requiring a manual adjustment stop. Note: CDEV operation requires the separately sold IIC Install Kit and CDEV-equipped front shocks, and the ICON Intelligent Control app requires an iOS device.

Built to Last and Be Rebuilt

The shock cylinder is a one-piece, hard-anodized, impact-extruded aluminum tube that resists corrosion and holds a consistent finish over years of use. The 7/8" shock shaft is induction hardened and chrome plated for durability under repeated cycling. A piggyback reservoir improves heat dissipation during prolonged off-road use, reducing shock fade on extended runs. Premium 5WT shock oil maintains consistent damping across a wide temperature range. Every V.S. 2.5 Aluminum Series shock is fully rebuildable and re-tunable, so the investment extends well beyond the first set of seals.

Features

• CDEV electronic valve: infinitely variable compression damping, adjustable from inside the cab via ICON Intelligent Control app
• Internal Bump Zone: 6061-billet aluminum manifold adds 20% damping force near full compression to resist harsh bottom-outs
• One-piece hard-anodized cylinder: impact-extruded aluminum construction for corrosion resistance and consistent finish
• 7/8" chrome-plated shaft: induction hardened for durability under repeated suspension cycling
• Piggyback reservoir: improves heat dissipation and reduces shock fade during extended off-road use
• Fully rebuildable and re-tunable: PTFE-lined spherical bearings and application-specific mounting hardware included

Specifications

Who This Is For and Isn't

These shocks suit 2014–2026 Ram 2500 owners running 0–1" rear lift with coil springs, or 3" rear lift with factory rear air springs, who want electronically adjustable compression damping and active terrain response for mixed on-road and off-road use.

These shocks do not fit Ram 2500 trucks outside the 2014–2026 model years, and they are not compatible with lift heights other than 0–1" (coil) or 3" (air ride) as stated. CDEV functionality is not operational without the separately sold ICON IIC Install Kit, compatible CDEV front shocks, and an iOS device running the ICON Intelligent Control app.

Common Questions

What lift heights are these shocks compatible with?

The ICON V.S. 2.5 Aluminum Piggyback Rear Shocks with CDEV are compatible with 0–1" rear lift on 2014–2026 Ram 2500 trucks equipped with rear coil springs, and with 3" rear lift on 2014–2026 Ram 2500 trucks equipped with factory rear air springs. No other lift heights are specified for this application.

What else is required to use the CDEV electronic damping feature?

CDEV operation on these rear shocks requires the separately sold ICON Intelligent Control (IIC) Install Kit, CDEV-equipped front shocks, and an iOS device to run the ICON Intelligent Control app. The CDEV valve is included with these shocks, but the full electronic system is not functional without those additional components.

Are these shocks rebuildable?

Yes. The ICON V.S. 2.5 Aluminum Series shocks are fully rebuildable and re-tunable. The one-piece hard-anodized aluminum cylinder, PTFE-lined spherical bearings, and CNC-machined 6061 aluminum components are all designed to be serviced, extending the usable life of the shock beyond the initial installation.

How does the Bump Zone work?

A 6061-billet aluminum manifold positioned a few inches below the top cap of the shock creates an internal Bump Zone. When the shock approaches full compression, this zone activates an additional 20% of damping force, resisting harsh bottom-outs and controlling suspension movement during high-velocity compression events such as hitting a ledge or large obstacle at speed.

How many shocks are included?

The ICON V.S. 2.5 Aluminum Piggyback Rear Shocks with CDEV are sold as a pair, meaning two rear shocks are included per order under SKU 217704EP.
