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

The ICON Vehicle Dynamics V.S. 2.5 Aluminum Series rear shock absorbers are a vehicle-specific, nitrogen-charged monotube piggyback pair built for the 2014–2026 Ram 2500, tuned in both length and damping to work with ICON's 0.5" Lift Performance Rear Coil Springs (PN 214206). Each shock features ICON's externally adjustable CDC Valve and an internal Bump Zone for high-velocity compression control.

10-Level Compression Adjustability on the Trail or the Street

The ICON CDC Valve is an externally adjustable valve that restricts oil flow into the piggyback reservoir, producing 10 distinct levels of compression damping force. Turning a single knob lets a driver dial in a softer setting for daily highway miles or a firmer setting before a washboard forest road, without removing a wheel or opening the shock body. That range of adjustment means one set of shocks can serve the same truck across genuinely different use cases rather than forcing a compromise at the factory middle.

Bump Zone and Piggyback Reservoir for High-Speed Control

A 6061 billet aluminum manifold positioned just below the shock's top cap creates an internal Bump Zone that adds 20% of damping force as the shock approaches full compression. At high velocity off-road, that extra resistance helps prevent harsh bottom-outs that can unsettle the truck or damage cargo. The piggyback reservoir separates the oil volume from the main shock body, improving heat dissipation and reducing shock fade during extended hard use on rough terrain.

Rebuildable Construction Built to Last

The shock body is a one-piece impact-extruded aluminum cylinder, CNC machined from 6061 aircraft-grade aluminum, which resists corrosion and holds tight tolerances over years of use. The 7/8" induction-hardened, chrome-plated shock shaft resists bending and surface wear. Every V.S. 2.5 Aluminum Series shock is 100% rebuildable and 100% revalveable, so the shock can be serviced or retuned rather than replaced when it eventually needs attention. Premium 5WT shock oil maintains consistent damping across a wide temperature range.

Features

• CDC Valve: 10-level externally adjustable compression damping with a single knob
• Internal Bump Zone: 6061 billet aluminum manifold adds 20% damping force near full compression
• Piggyback Reservoir: nitrogen-charged monotube with separate reservoir for improved heat dissipation
• 7/8" Shock Shaft: induction-hardened, chrome-plated for durability and corrosion resistance
• Rebuildable and Revalveable: 100% serviceable; vehicle-specific length and damping tune for the Ram 2500
• OE-Style Mounting: polyurethane bushings, forged steel stems, PTFE-lined spherical bearings, and application-specific hardware

Specifications

Who This Is For and Isn't

These shocks suit 2014–2026 Ram 2500 owners running ICON's 0.5" Lift Performance Rear Coil Springs (PN 214206) who want externally adjustable, rebuildable rear damping for mixed on-road and off-road use.

These shocks are not compatible with Ram 2500 trucks equipped with factory rear air ride suspension. The length and damping tune are optimized specifically for the ICON 0.5" lift coil; they are not designed as a drop-in replacement for stock or other-height coil spring setups. Coil springs are not included and must be purchased separately.

Common Questions

Do these shocks fit a Ram 2500 with factory air ride?

No. Per ICON Application Note #105, these V.S. 2.5 Aluminum Series rear shocks are not compatible with Ram 2500 trucks equipped with factory rear air ride suspension. They are designed for the standard coil-spring rear suspension found on 2014–2026 Ram 2500 models without the air ride option.

Are the coil springs included with this purchase?

No. This listing covers the pair of rear shock absorbers only. The shocks are tuned specifically for use with ICON's 0.5" Lift Performance Rear Coil Springs, part number 214206, which must be purchased separately. Running these shocks with a different spring height may affect damping performance.

How does the CDC Valve compression adjustment work?

The ICON CDC Valve is an externally accessible knob on the piggyback reservoir that restricts oil flow between the shock body and the reservoir. Turning the knob cycles through 10 levels of compression damping force, from softer settings suited to highway driving to firmer settings for high-speed off-road use, without disassembling the shock.

Can these shocks be rebuilt or revalved if they wear out?

Yes. Every ICON V.S. 2.5 Aluminum Series shock is 100% rebuildable and 100% revalveable. The one-piece impact-extruded aluminum body and serviceable internals mean the shock can be disassembled, seals replaced, and valving changed by a qualified shop rather than requiring full replacement.

What is the Bump Zone, and why does it matter?

The Bump Zone is created by a 6061 billet aluminum manifold positioned just below the shock's top cap. As the shock approaches full compression, this manifold increases damping force by 20%, helping prevent harsh bottom-outs during high-velocity impacts off-road. The result is better control and reduced shock to the truck's frame and cab when hitting sharp terrain features at speed.
