ICON V.S. 2.5 Remote/CDCV Front Shocks for 2003-2012 Ram 2500/3500 HD 4.5" Lift

The ICON Vehicle Dynamics V.S. 2.5 Aluminum Series Remote/CDCV Front Shocks are a vehicle-specific pair engineered for 2003–2012 Ram 2500/3500 HD trucks running a 4.5-inch lift on 4WD models. Each shock is tuned in both length and damping specifically for this application, pairing a remote reservoir with ICON's CDC Valve for externally adjustable compression damping across 10 distinct levels.

Dialed-In Damping for Heavy-Duty Use

The CDC (Compression Damping Control) Valve lets the driver adjust compression damping force with a single knob, cycling through 10 high-resolution settings without tools or disassembly. Restricting oil flow into the remote reservoir changes how the shock responds to impacts, so the same truck can be softened for highway miles and firmed up for loaded trail work without swapping components.

Remote Reservoir Keeps Heat in Check

Heat buildup during extended off-road use degrades damping consistency, a condition called shock fade. The remote reservoir on each shock increases oil volume and surface area, dissipating heat faster than a standard twin-tube or non-reservoir monotube design. Premium-grade 5WT shock oil maintains consistent damping across a wide temperature range, so performance holds up on long runs rather than degrading as the fluid heats.

Built to Last and Be Rebuilt

The shock body is a one-piece impact-extruded 6061 aircraft-grade aluminum cylinder, CNC machined for consistent wall thickness and a corrosion-resistant finish. The 7/8-inch shock shaft is induction hardened and chrome plated for wear resistance. PTFE-lined spherical bearings at the mounting points reduce friction and tolerate the articulation angles common in lifted heavy-duty applications. Both shocks are 100% rebuildable and 100% revalveable, meaning worn seals or a damping retune does not require replacing the entire unit.

Features

• CDC Valve: externally adjustable compression damping with 10 levels, turned by hand
• Remote reservoir: nitrogen-charged monotube design with separate reservoir for improved heat dissipation
• Vehicle-specific valving: length and damping tune set for the 2003–2012 Ram 2500/3500 HD 4.5-inch lift application
• 7/8" hardened shaft: induction-hardened, chrome-plated for durability under heavy loads
• 6061 aluminum construction: CNC-machined, one-piece impact-extruded cylinders resist corrosion
• Fully rebuildable and revalveable: serviceable in the field or at a shop without replacing the shock body

Specifications

Who This Is For and Isn't

These shocks suit owners of 2003–2012 Ram 2500/3500 HD trucks with a 4WD drivetrain running a 4.5-inch lift who want externally adjustable, rebuildable performance shocks with remote reservoirs for off-road use and on-road comfort.

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

Common Questions

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

No. The ICON V.S. 2.5 Remote/CDCV Front Shocks (SKU 217810CP) are designed for 4WD models only. They will not fit 2WD Ram 2500 or 3500 trucks from any model year.

What lift height are these shocks built for?

These front shocks are configured specifically for a 4.5-inch lift on 2003–2012 Ram 2500/3500 HD 4WD trucks. The length and damping tune are set for that lift height; using them with a significantly different lift may affect performance and geometry.

How does the CDC Valve compression adjustment work?

The CDC (Compression Damping Control) Valve is an external knob on the remote reservoir that restricts oil flow between the shock body and reservoir. Turning it cycles through 10 levels of compression damping force, from softer highway settings to firmer off-road tuning, without removing the shock or using tools.

Are these shocks rebuildable if seals wear out?

Yes. The ICON V.S. 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable. Worn seals can be replaced and the valving can be changed without discarding the shock body, which extends the service life of the unit.

What is included in this listing?

This listing includes a pair of ICON V.S. 2.5 Remote/CDCV front shocks with application-specific mounting hardware, configured for the 2003–2012 Ram 2500/3500 HD 4WD 4.5-inch lift application. Rear shocks, springs, and other suspension components are not included and are sold separately.
