Overview:

The ICON 2.5 Series Rear Shocks are precision-engineered performance shocks designed specifically for Dodge Ram 2500 and 3500 models from 2003 through 2013. Built to deliver exceptional off-road capability while maintaining a smooth and controlled ride on the street, these shocks are tailored to the unique suspension characteristics of each vehicle application. Whether you’re tackling rugged trails or cruising highways, ICON’s Vehicle Specific (V.S.) 2.5 Aluminum Series shocks provide superior damping control and durability for lifted Ram trucks with 2-3" rear lifts.

These shocks are ideal for enthusiasts who demand reliable performance and ride quality in demanding conditions. With fully rebuildable and revalveable construction, they offer long-term serviceability and customization to suit your driving style and terrain.

Key Features:

Designed with advanced technology and premium materials, the ICON 2.5 Series Rear Shocks include:

• One-piece digressive piston design with vehicle-specific valving for optimized performance and ride comfort
• ICON’s patented internal “Bump Zone” that increases damping force by 20% near full compression to prevent harsh bottom outs
• Externally adjustable ICON CDC Valve offering 10 levels of high-resolution compression damping adjustment via a simple knob
• Durable one-piece impact extruded aluminum cylinders providing excellent corrosion resistance and a consistent finish
• Piggyback reservoir design for improved heat dissipation and reduced shock fade during extended use
• Premium grade 5WT shock oil ensuring consistent damping performance across a wide temperature range
• PTFE-lined spherical bearings and application-specific mounting hardware for precise fit and reduced wear
• 7/8” diameter induction hardened, chrome-plated shock shaft for strength and smooth operation
• Nitrogen charged monotube design with piggyback reservoir for superior response and durability
• 6061 aircraft grade aluminum CNC machined components for lightweight strength and reliability
• 100% rebuildable and revalveable for long-term maintenance and tuning flexibility

Construction & Design:

ICON’s 2.5 Series Rear Shocks are crafted from premium materials engineered for rugged use and longevity. The shock bodies are made from impact-extruded aluminum, providing a lightweight yet corrosion-resistant housing. The shock shafts are induction hardened and chrome plated to resist wear and maintain smooth piston travel. The piggyback reservoir design enhances heat dissipation, reducing shock fade during prolonged off-road or heavy-duty use.

Unique to ICON is the use of a 6061 billet aluminum manifold positioned just below the shock’s top cap, creating an internal Bump Zone. This innovation increases damping force by 20% during high-velocity compression, preventing harsh bottom outs and improving suspension control. The externally adjustable CDC Valve allows fine-tuning of compression damping, enabling drivers to tailor shock performance to their specific needs.

Installation & Fitment:

These shocks are designed as direct replacements for Dodge Ram 2500 and 3500 models from 2003 to 2013 with 2-3" rear lifts. Installation is straightforward with application-specific mounting hardware included, requiring no major modifications. The shocks are engineered to fit precisely, ensuring proper suspension geometry and optimal performance right out of the box.

What's Included:

• Pair of ICON 2.5 Series Rear Shocks with piggyback reservoirs
• Application-specific mounting hardware
• Adjustable CDC Valve knobs installed
• Installation instructions

Ideal For:

These shocks are perfect for Dodge Ram 2500 and 3500 owners who have lifted their trucks 2 to 3 inches and seek enhanced off-road performance without sacrificing street ride quality. They are well-suited for enthusiasts who demand durability, tunability, and consistent damping in a variety of driving conditions, including trail riding, towing, and daily driving.

Whether you’re upgrading your suspension for rugged terrain or improving highway comfort, ICON’s 2.5 Series Rear Shocks deliver a balanced combination of control, comfort, and longevity tailored specifically to your Ram truck.

ICON Vehicle Dynamics builds performance suspension components for trucks and SUVs—think coilovers, shocks, lift/leveling systems, and supporting hardware engineered for hard off-road use. Their setups are designed to improve control, ride quality, and durability when you’re pushing faster over rough terrain or building a capable overland/trail rig.
