ICON V.S. 2.5 Aluminum Series Rear Piggyback Shock Pair for 2014-2026 Ram 2500

The ICON V.S. 2.5 Aluminum Series Rear Shock Pair is a vehicle-specific, nitrogen-charged monotube shock set built for 2014–2026 Ram 2500 trucks, fitting 0–1" rear lift on coil-spring models and 3" rear lift on factory air-ride models. Sold as a matched pair, each shock is tuned in both length and damping specifically for this application.

Bump Zone Technology Prevents Harsh Bottom-Outs

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. For a Ram 2500 carrying a loaded bed, towing, or running at speed over rough terrain, that extra resistance is the difference between a controlled suspension stroke and a jarring bottom-out. The effect is progressive: it engages only when the shock is compressing hard, so everyday ride quality is not sacrificed to get it.

Piggyback Reservoir Fights Heat and Fade

Extended off-road runs and repeated hard compressions generate heat that degrades shock oil and causes fade. The piggyback reservoir increases fluid volume and surface area, dissipating heat faster and keeping damping consistent through prolonged use. Premium-grade 5WT shock oil maintains stable viscosity across a wide temperature range, so the tune the shock was built with is the tune it delivers whether the ambient temperature is 20°F or 100°F.

Built to Be Rebuilt and Retuned

Every V.S. 2.5 Aluminum Series shock is 100% rebuildable and 100% revalveable. The one-piece impact-extruded aluminum cylinder resists corrosion and holds a consistent finish over years of use. The 7/8" induction-hardened, chrome-plated shock shaft and PTFE-lined spherical bearings are matched to application-specific mounting hardware, so the shock installs correctly and moves freely through its full range without binding. Buyers who want a more user-defined compression tune can consider the ICON CDCV (Compression Damping Control Valve) variant instead.

Features

• Internal Bump Zone: 6061 billet aluminum manifold adds 20% damping force near full compression to control high-velocity inputs
• Piggyback reservoir: nitrogen-charged monotube design with external reservoir for improved heat dissipation and reduced fade
• Vehicle-specific valving: length and damping tune configured for the 2014–2026 Ram 2500 application
• 7/8" shock shaft: induction-hardened and chrome-plated for durability and corrosion resistance
• 5WT shock oil: premium-grade fluid for consistent damping across a wide temperature range
• Rebuildable and revalveable: 100% serviceable for long-term ownership and tuning flexibility

Specifications

Who This Is For and Isn't

These shocks suit 2014–2026 Ram 2500 owners running 0–1" rear lift on a coil-spring suspension or 3" rear lift on a factory air-ride suspension, who want a vehicle-specific damping tune with long-term serviceability for off-road and towing use.

These shocks do not fit Ram 2500 trucks outside the 2014–2026 model years, do not cover lift heights other than those stated in Application Notes #564 and #565, and are not compatible with front suspension positions. Buyers wanting user-adjustable compression damping should look at the ICON CDCV variant rather than this fixed-tune shock.

Common Questions

What Ram 2500 model years and lift heights do these shocks fit?

The ICON 217704P rear shock pair fits 2014–2026 Ram 2500 trucks. On coil-spring models, they are compatible with 0–1" of rear lift (Application Note #564). On factory air-ride models, they are compatible with 3" of rear lift (Application Note #565). No other model years or lift heights are covered by this part number.

What is the Bump Zone and what does it do?

The Bump Zone is created by a 6061 billet aluminum manifold positioned just below the top cap of each shock. As the shock compresses hard and fast (over a sharp bump, a dip, or during aggressive off-road driving), the Bump Zone engages and adds 20% more damping force to resist harsh bottom-outs and keep the suspension controlled through high-velocity inputs.

Why does the piggyback reservoir matter for a truck used on the street and trail?

Repeated compression cycles generate heat that thickens shock oil and causes fade, meaning the shock stops damping consistently. The piggyback reservoir on these ICON V.S. 2.5 shocks increases fluid volume and surface area, dissipating heat more effectively so damping stays consistent during extended off-road runs or long towing hauls, not just for the first few miles.

Can these shocks be rebuilt or revalved if they wear out or I want a different tune?

Yes. Every ICON V.S. 2.5 Aluminum Series shock is 100% rebuildable and 100% revalveable. Worn seals and oil can be replaced to restore original performance, and the internal valving can be changed by a qualified shop if a different damping tune is needed, extending the useful life of the shock well beyond what a sealed, non-serviceable unit offers.

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

This listing covers a matched rear pair (two shocks) for the 2014–2026 Ram 2500. Application-specific mounting hardware is included with the shocks. An installation guide is available for this application.
