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

The ICON Vehicle Dynamics V.S. 2.5 Aluminum Series rear shock absorbers with piggyback reservoir and CDC Valve are a vehicle-specific pair built for 2014–2026 Ram 2500 trucks equipped with factory rear air ride, compatible with 0–2" of rear lift. Each shock is configured for this exact application in both length and damping tune, and the pair ships as SKU 217708CP.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Bump Zone Technology Prevents Harsh Bottom-Outs

A 6061 billet aluminum manifold positioned a few inches below the top cap creates ICON's internal Bump Zone. When the shock approaches full compression, this zone increases damping force by 20%, giving the suspension more resistance exactly when it needs it most during high-velocity compression events on rough terrain. The result is a shock that controls wheel travel aggressively at the limit without sacrificing ride quality in everyday driving.

10-Level CDC Valve Lets You Tune on the Trail

The externally adjustable CDC (Compression Damping Control) Valve restricts oil flow into the piggyback reservoir across 10 discrete levels. Turning the knob firms up compression damping for loaded highway towing or loosens it for technical off-road terrain, with no tools and no disassembly required. The piggyback reservoir itself increases oil volume to dissipate heat during sustained off-road use, reducing shock fade on long runs.

Built to Be Rebuilt

Every V.S. 2.5 Aluminum Series shock is 100% rebuildable and 100% revalveable. The one-piece impact-extruded aluminum cylinder resists corrosion, and CNC-machined 6061 aircraft-grade aluminum components hold tight tolerances over years of use. Premium 5WT shock oil maintains consistent damping across a wide temperature range. If the truck's load, lift, or use case changes, the shock can be revalved to match the new application rather than replaced outright.

Features

• CDC Valve: 10-level externally adjustable compression damping with a turn of a knob
• Internal Bump Zone: 6061 billet aluminum manifold adds 20% damping force near full compression
• Piggyback Reservoir: Nitrogen-charged monotube design with separate reservoir for heat dissipation and fade resistance
• 7/8" Shock Shaft: Induction-hardened, chrome-plated for durability
• OE-Style Mounting: Polyurethane bushings, forged steel mounting stems, and PTFE-lined spherical bearings for factory-type fitment
• Fully Rebuildable and Revalveable: One-piece digressive piston with vehicle-specific valving; serviceable for long-term ownership

Specifications

Who This Is For and Isn't

These shocks suit 2014–2026 Ram 2500 owners running factory rear air springs who want a rebuildable, externally adjustable rear shock with heat-resistant piggyback reservoir performance for towing, overlanding, or mixed on- and off-road use with up to 2" of rear lift.

These shocks do not fit Ram 2500 trucks without factory rear air ride, Ram 1500 or Ram 3500 applications, or any front shock position. They are not compatible with rear lift exceeding 2" per Application Note #569.

Common Questions

What Ram 2500 model years and configurations do these shocks fit?

These ICON V.S. 2.5 Aluminum Series rear shocks fit 2014–2026 Ram 2500 trucks equipped with the factory rear air ride suspension. Per Application Note #569, they are compatible with 0–2" of rear lift. They do not fit Ram 2500 trucks without factory rear air springs.

How does the CDC Valve work, and do I need tools to adjust it?

The CDC (Compression Damping Control) Valve on these ICON shocks is an external knob that restricts oil flow into the piggyback reservoir. Turning it selects from 10 levels of compression damping force, with no tools required. Firmer settings suit loaded towing or high-speed off-road; softer settings suit technical crawling or daily driving.

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

The Bump Zone is an internal feature created by a 6061 billet aluminum manifold near the top of the shock body. As the shock nears full compression, the Bump Zone increases damping force by 20%, resisting harsh bottom-outs during high-velocity impacts. This protects the suspension and the truck's frame without making the ride stiff during normal travel.

Can these shocks be rebuilt or revalved if my setup changes?

Yes. Every ICON V.S. 2.5 Aluminum Series shock is 100% rebuildable and 100% revalveable. If the truck's lift height, load, or intended use changes, the shock can be revalved to match the new application rather than replaced outright, which extends the usable life of the unit.

How many shocks are included, and what mounting hardware comes with them?

This listing includes a pair of two rear shocks. Mounting uses polyurethane bushings, forged steel mounting stems, and PTFE-lined spherical bearings for OE factory-type fitment. Application-specific mounting hardware is included with the shocks.
