ICON Vehicle Dynamics 2014-2026 Ram 2500 4WD Diesel 2.5" Stage 4 Suspension System with Performance Rear Coil Springs

The ICON Vehicle Dynamics Stage 4 Suspension System for 2014–2026 Ram 2500 4WD Diesel (coil-spring rear) delivers 2.5 inches of front lift and 0.5 inches of rear lift through a matched set of dual-rate front coil springs, triple-rate rear performance coil springs, 2.5 Aluminum Series remote reservoir front shocks, 2.5 Aluminum Series piggyback reservoir rear shocks, and front and rear adjustable track bars, all with Continuous Damping Control Valves (CDCV) for external ride-quality tuning.

External Damping Adjustment Without Disassembly

Every shock absorber in this system carries an ICON CDC Valve, providing 10 settings of compression damping adjustment from soft to hard. Each CDCV is adjusted externally on the shock body, so a driver can shift between a compliant highway tune and a firmer off-road setup without removing a wheel or opening a reservoir. That flexibility matters on a 3/4-ton truck that may run pavement one day and washboard the next.

Axle Centering and Bushing-Free Precision

The front and rear adjustable track bars use PTFE-lined spherical bearings in place of factory rubber bushings. Eliminating bushing deflection tightens steering response and reduces the vague, wandering feel that worn or flexible factory joints introduce. The adjustability lets an installer center the front axle under the truck after the lift, correcting the geometry that a fixed-length bar cannot address. The result is less body roll than stock and no driveshaft modifications required.

Triple-Rate Rear Springs for Varied Loads

The rear performance coil springs use three progressive rates rather than a single fixed rate. The lighter initial rate smooths out washboard roads and small whoops at unladen weight. A secondary rate maintains ride quality as load increases. The aggressive third overload rate resists bottom-outs and provides payload support, though at a reduced ride height. This progression is calibrated specifically for diesel-powered Ram 2500 trucks and is not rated for gas engines.

Features

• 2.5 Aluminum Series Remote Reservoir Front Shocks: matched and tuned to the dual-rate front coil springs for increased wheel travel over stock
• 2.5 Aluminum Series Piggyback Reservoir Rear Shocks: complement the triple-rate rear coil springs in both length and damping tune
• Front and Rear Adjustable Track Bars: PTFE-lined spherical bearings eliminate bushing deflection; adjustability centers axles after lift
• CDCV on All Four Shocks: 10 externally accessible compression damping settings, soft to hard
• Triple-Rate Rear Performance Coil Springs: 0.5 inches of rear lift; progressive rates for unladen ride, load support, and bottom-out resistance
• OEM Wheels and Tires Compatible: fits stock wheel and tire sizes without modification

Who This Is For and Isn't

This system suits 2014–2026 Ram 2500 4WD owners running a diesel engine with a factory coil-spring rear suspension who want a 2.5-inch front lift, improved off-road ride quality, and externally tunable damping for mixed on- and off-road use including rough terrain and dirt roads.

This system does not fit Ram 2500 2WD models, gas-engine Ram 2500 trucks, or any Ram 2500 equipped with factory rear air ride. The Ram 2500 Rebel receives only 0.5 inches of front lift, not 2.5 inches. Helper air bags are recommended for vehicles used to haul or tow heavy loads (not included in this kit); the performance rear springs may reduce ride height under towing conditions. ADAS recalibration is required after installation and is not included.

Common Questions

Does this system fit a Ram 2500 with a gas engine?

No. The ICON Stage 4 system for 2014–2026 Ram 2500 is rated for diesel engines only. The springs in this kit are specifically calibrated for the weight of a diesel-powered Ram 2500; a gas-engine application is outside the stated fitment and is not supported.

What lift height does the Ram 2500 Rebel get with this system?

The ICON Stage 4 system provides 0.5 inches of front lift on the Ram 2500 Rebel submodel, not the 2.5 inches delivered on most other Ram 2500 submodels. Rear lift is 0.5 inches across all compatible submodels. Confirm your submodel before ordering.

Can this system be used on a Ram 2500 with factory rear air ride?

No. The ICON Stage 4 system for 2014–2026 Ram 2500 is not compatible with vehicles equipped with factory rear air ride suspension. It is designed for the coil-spring rear suspension configuration only.

Is ADAS recalibration required after installing this system?

Yes. Installation of this ICON Stage 4 suspension system requires recalibration of Advanced Driver Assistance Systems (ADAS) after the lift is complete. Recalibration is not included with the kit and must be performed separately, typically by a dealer or qualified shop with the appropriate diagnostic equipment.

What is the CDCV, and how is it adjusted?

CDCV stands for Continuous Damping Control Valve. All four shocks in this Stage 4 system include a CDCV that provides 10 settings of compression damping adjustment, ranging from soft to hard. Each CDCV is adjusted externally on the shock body, with no disassembly required to change the damping setting.

Are helper air bags needed for towing with this system installed?

Helper air bags are recommended when hauling or towing heavy loads with this ICON Stage 4 system installed. The performance rear coil springs may cause reduced ride height under towing conditions. Helper air bags are not included in this kit and must be sourced and installed separately.
