ICON Stage 3 Suspension System for 2003-2012 Ram 2500/3500 4WD 2.5 Inch Lift

The ICON Stage 3 Suspension System is a complete mid-level lift kit for 2003–2012 Ram 2500/3500 4WD trucks, delivering a 2.5-inch lift through a matched set of dual-rate coil springs, 2.0 Aluminum Series remote reservoir shocks, an adjustable track bar, and front steel link bars. Springs in this system are rated for diesel engines only. The kit fits both Ram 2500 and Ram 3500 four-wheel-drive applications from the same model years.

Remote Reservoir Shocks for Sustained Off-Road Performance

The front and rear 2.0 Aluminum Series remote reservoir shocks separate the fluid and gas chambers, giving the dampers more capacity to shed heat during extended off-road use. That separation maintains consistent damping longer than a standard shock body can, so ride quality holds up through repeated hits rather than fading as the fluid heats up. The shocks are fully serviceable, meaning worn internals can be rebuilt rather than replaced outright.

Adjustable Track Bar With FK Bearings

The bearing-style adjustable track bar replaces the factory rubber joint with PTFE-lined FK bearings, which resist flex under load and allow precise lateral adjustment. That adjustability lets the installer center the front axle under the truck after the lift is set, correcting the axle offset that a fixed-length bar cannot address. The result is more predictable steering feel on and off pavement.

Steel Link Bars and No Driveshaft Modifications

Front steel upper and lower link bars replace the factory units and reduce the binding that builds up in rubber link bushings as suspension cycles through its range. The geometry of the Stage 3 system is designed so no driveshaft modifications are needed, and towing capacity is unchanged from the factory rating. Body roll is reduced compared to stock.

Features

• 2.0 Aluminum Series remote reservoir shocks: front 2.5 in application, rear 0–3 in application; fully serviceable
• Adjustable track bar: PTFE-lined FK bearings for rigidity and front-axle centering adjustability
• Front steel upper and lower links: reduce bushing bind and increase alignment range
• Polyurethane bumpstops and sway bar drop brackets: included in the system
• No driveshaft modifications required; towing capacity unchanged

Specifications

Who This Is For and Isn't

This system suits 2003–2012 Ram 2500 and Ram 3500 four-wheel-drive owners running diesel engines who want a 2.5-inch lift with a meaningful upgrade to damping, front-axle tracking, and link geometry for off-road or overlanding use.

This system does not fit gas-engine Ram HD trucks. The coil springs are rated for diesel engines only. It does not fit two-wheel-drive Ram 2500/3500 models, and it does not fit Ram 1500 or any model year outside 2003–2012. Tires larger than 33×11.50 inches may require fender trimming and additional modifications not included in this kit.

Common Questions

Will this system work with a gas-engine Ram 2500 or 3500?

The ICON Stage 3 system for 2003–2012 Ram 2500/3500 4WD includes coil springs rated for diesel engines only. Gas-engine applications are outside the stated fitment for this kit and would require a different spring specification.

Does installing this kit require driveshaft modifications?

No driveshaft modifications are needed for the ICON Stage 3 system on 2003–2012 Ram 2500/3500 4WD trucks. The system geometry is designed to work within the factory driveline angles at the stated 2.5-inch lift height.

What is the largest tire that fits without cutting or trimming?

The ICON Stage 3 system on 2003–2012 Ram 2500/3500 4WD accommodates tires up to 33×11.50 inches without fender trimming. Larger tires may fit but will require fender trimming and additional modifications.

Are the shocks rebuildable, or do they need to be replaced as a unit?

The 2.0 Aluminum Series remote reservoir shocks included in this Stage 3 system are fully serviceable, meaning the internals can be rebuilt rather than requiring full shock replacement when they wear.

Does this kit affect towing capacity?

The ICON Stage 3 system for 2003–2012 Ram 2500/3500 4WD is designed with no change to the factory towing capacity. The system geometry and component selection preserve the truck's rated tow rating.
