ICON V.S. 2.5 Piggyback Rear Shocks for 2003-2012 Ram 2500/3500 HD 2-3 in Lift Pair

The ICON Vehicle Dynamics V.S. 2.5 Aluminum Series Piggyback Rear Shocks are a vehicle-specific pair built for 2003–2012 Ram 2500/3500 HD trucks running 2–3 inches of lift. Each shock is tuned in both length and damping specifically for this application, delivering controlled off-road performance and a composed street ride without compromise. The pair ships ready to install on the rear axle of the supported Ram HD platform.

Bump Zone Control at High-Speed Compression

The V.S. 2.5 Piggyback shocks use a 6061 billet aluminum manifold positioned just below the top cap to create ICON's internal Bump Zone. When the shock approaches full compression, this zone adds 20% more damping force, resisting harsh bottom-outs during high-speed off-road hits without stiffening the everyday ride. For Ram HD owners who push their trucks on rough terrain, that extra resistance at the limit of travel is the difference between a controlled landing and a jarring impact.

Heat Management Through the Piggyback Reservoir

The piggyback reservoir separates the nitrogen charge from the shock oil, giving the fluid more volume and more surface area to shed heat during extended off-road use. Shock fade (the loss of damping performance as oil heats up) is a real problem on long washboard runs or repeated high-speed hits. The remote reservoir design keeps the 5WT shock oil working consistently across a wide temperature range, so the 20th hit feels like the first.

Built to Be Rebuilt and Retuned

Every V.S. 2.5 Piggyback shock is 100% rebuildable and 100% revalveable. When seals wear or driving style changes, the shock can be serviced and revalved rather than replaced, a meaningful long-term value for a truck used hard. Owners who want a more user-defined compression tune can upgrade these shocks to ICON's Compression Damping Control Valve (CDCV) configuration.

Features

• Internal Bump Zone: 6061 billet aluminum manifold adds 20% damping force as the shock approaches full compression
• Piggyback Reservoir: nitrogen-charged monotube with separate reservoir for improved heat dissipation and reduced shock fade
• Vehicle-Specific Valving: one-piece digressive piston tuned in length and damping for the 2003–2012 Ram 2500/3500 HD at 2–3 in lift
• 7/8 in Shock Shaft: induction-hardened, chrome-plated for durability and corrosion resistance
• Premium Materials: one-piece impact-extruded aluminum cylinders, PTFE-lined spherical bearings, and application-specific mounting hardware
• Rebuildable and Revalveable: fully serviceable; CDCV upgrade available for adjustable compression damping

Who This Is For and Isn't

These shocks suit 2003–2012 Ram 2500/3500 HD owners running 2–3 inches of rear lift who want a vehicle-specific damping tune for mixed on-road and off-road use, and who value a shock that can be rebuilt and revalved over its service life.

These shocks do not fit Ram 1500, Ram 2500/3500 trucks outside the 2003–2012 model years, or lifted Ram HD trucks outside the 2–3 inch lift range. They are rear shocks only and do not include front shocks, springs, or any other suspension components.

Common Questions

What trucks do these shocks fit?

These ICON V.S. 2.5 Piggyback Rear Shocks fit 2003–2012 Ram 2500 and Ram 3500 HD trucks with 2–3 inches of rear lift. They are not compatible with Ram 1500 or with Ram HD trucks outside that model-year range or lift window.

Are these shocks sold as a pair or individually?

The ICON 217701P (SKU 217701P) is sold as a pair, two rear shocks covering both sides of the rear axle on the supported Ram 2500/3500 HD application.

What is the Bump Zone and why does it matter?

The Bump Zone is created by a 6061 billet aluminum manifold inside the V.S. 2.5 shock body. As the shock nears full compression, the Bump Zone increases damping force by 20%, resisting harsh bottom-outs during high-speed off-road impacts without adding stiffness to normal driving.

Can these shocks be rebuilt or retuned later?

Yes. The ICON V.S. 2.5 Piggyback shocks are 100% rebuildable and 100% revalveable. They can also be upgraded to ICON's Compression Damping Control Valve (CDCV) configuration for adjustable compression damping if a more user-defined tune is desired later.

Do these shocks include springs or front shocks?

This listing covers the rear piggyback shocks only, two shocks for the rear axle. Springs, front shocks, and other suspension components are not included and would need to be sourced separately.
