ICON V.S. 2.5 Remote Reservoir Front Shocks for 2003-2012 Ram 2500/3500 HD 4WD 4.5" Lift, Pair

The ICON V.S. 2.5 Aluminum Series Remote Reservoir Front Shocks are a vehicle-specific pair engineered for 2003–2012 Dodge Ram 2500/3500 HD 4WD trucks running a 4.5-inch lift. Each shock is tuned in both length and damping specifically for this application, using a nitrogen-charged monotube body with a remote reservoir and a 7/8-inch induction-hardened, chrome-plated shaft. Sold as a pair for the front axle.

Remote Reservoir Design Manages Heat on Long Runs

The remote reservoir separates a portion of the shock fluid from the main body, giving heat generated during hard use more surface area to dissipate. For Ram 2500/3500 HD owners who spend extended time on washboard roads, rocky two-tracks, or loaded towing runs, this means the shocks maintain consistent damping force rather than fading as fluid temperature climbs. The nitrogen-charged monotube construction further resists aeration that can make a shock feel vague or inconsistent mid-trail.

Vehicle-Specific Valving, Not a Generic Tune

ICON configures the one-piece digressive piston valving for this exact Ram HD application rather than applying a shared tune across multiple platforms. The result is a damping curve calibrated to the weight, geometry, and 4.5-inch lift height of these trucks. Premium 5WT shock oil maintains that tune across a wide temperature range, from cold desert mornings to sustained high-speed desert running. PTFE-lined spherical bearings and application-specific mounting hardware are included so the shock installs correctly without improvised adapters.

Built to Be Rebuilt, Not Replaced

The V.S. 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable. One-piece impact-extruded 6061 aircraft-grade aluminum cylinders resist corrosion and hold tight tolerances over years of use. When valving needs refreshing after high-mileage off-road use, the shock can be rebuilt rather than discarded, which extends the service life and allows revalving if the truck's use case or load changes.

Features

• Remote reservoir monotube: nitrogen-charged design with separate reservoir for improved heat dissipation and fade resistance
• Vehicle-specific valving: one-piece digressive piston tuned in length and damping for 2003–2012 Ram 2500/3500 HD at 4.5-inch lift
• 7/8" hardened shaft: induction-hardened, chrome-plated for durability under heavy-duty use
• 6061 aluminum construction: CNC-machined components and impact-extruded cylinder for corrosion resistance
• 100% rebuildable and revalveable: serviceable in the field or at a shop without replacing the entire shock body
• Included hardware: PTFE-lined spherical bearings and application-specific mounting hardware

Specifications

Who This Is For and Isn't

These shocks suit 2003–2012 Dodge Ram 2500/3500 HD owners running a 4WD drivetrain with a 4.5-inch lift who want a remote-reservoir shock with vehicle-specific damping tuning for mixed on-road and off-road use.

These shocks do not fit 2WD Ram 2500/3500 models, any Ram 1500, or Ram HD trucks outside the 2003–2012 model year range. They are front shocks only and do not replace rear shocks. Buyers seeking a user-adjustable compression damping tune should consider ICON's CDCV shock variant instead.

Common Questions

Do these shocks fit a 2WD Ram 2500 or 3500?

No. The ICON V.S. 2.5 Remote Reservoir Front Shocks (217810P) are designed for 4WD models only. They are not compatible with 2WD Ram 2500 or 3500 trucks.

What lift height are these shocks built for?

These shocks are configured specifically for a 4.5-inch lift on 2003–2012 Ram 2500/3500 HD 4WD trucks. ICON tunes both the length and damping for this exact lift height; using them at a significantly different lift height is not recommended.

Can these shocks be rebuilt or revalved later?

Yes. The ICON V.S. 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable, meaning the internals can be serviced or the valving changed without replacing the entire shock body.

What is included with this pair?

The pair includes two front shocks with PTFE-lined spherical bearings and application-specific mounting hardware. No rear shocks are included. An optional ICON reservoir hose shield kit is available separately.

Is there a California Proposition 65 warning for this product?

Yes. This product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm. This warning applies to California residents.
