ICON Vehicle Dynamics 2014-2026 Ram 2500 4WD Diesel 2.5" Lift Stage 4 Suspension System

The ICON Vehicle Dynamics Stage 4 Suspension System lifts 2014–2026 Ram 2500 4WD Diesel trucks 2.5" at the front and is engineered specifically for trucks equipped with factory OEM rear air springs. The system pairs dual-rate front coil springs with 2.5 Aluminum Series reservoir shocks front and rear, an adjustable front track bar, and all necessary bracketry and hardware. Note: the Rebel submodel receives 0.5" of front lift rather than 2.5".

Reservoir Shocks with CDC Valve Adjustment

All four shocks in this system are ICON 2.5 Aluminum Series units fitted with Compression Damping Control (CDC) Valves, giving 10 externally accessible settings from soft to firm. The reservoir design extends consistent damping performance during sustained heavy use by keeping operating temperatures lower than a non-reservoir shock can manage, which matters on long off-road runs, loaded towing pulls, or repeated rough-road cycles. Being able to dial compression damping from outside the shock means tuning for a highway commute or a loaded trailer pull takes seconds, not a shock rebuild.

Dual-Rate Springs and Adjustable Track Bar

The front dual-rate coil springs are match-tuned to the 2.5 Aluminum Series shocks and rated specifically for diesel engine weight, a meaningful distinction on a heavy-duty truck where spring rate directly affects both ride quality and towing stability. The front adjustable track bar uses PTFE-lined spherical bearings in place of the factory rubber bushings, eliminating deflection under load and allowing the front axle to be centered under the truck after the lift is installed. No drive shaft modifications are required.

Air Ride Compatibility Preserved

ICON designed the rear components of this system around the Ram 2500's factory air spring assembly, positioning the airbags and associated hardware so they are not over-traveled or damaged at ride height. All factory air ride modes remain fully functional after installation. The system is compatible with 0–2" of rear lift on trucks equipped with factory rear air springs. For buyers who want adjustable rear ride height, the optional ICON 2" Air Ride Kit (Part #214212, sold separately) allows end-user adjustment from stock height to 2" above stock.

Features

• 2.5 Aluminum Series Reservoir Shocks: front and rear, fully serviceable, with CDCV for 10 compression damping settings
• Diesel-Rated Dual-Rate Front Coil Springs: match-tuned to the included shocks for this application
• Adjustable Front Track Bar: PTFE-lined spherical bearings, centers front axle after lift installation
• Factory Air Ride Preserved: rear components designed to maintain full OEM air ride mode functionality
• No Drive Shaft Modifications Required: installs without driveline changes
• ADAS Recalibration Required: Advanced Driver Assistance Systems must be recalibrated after installation

Specifications

Who This Is For and Isn't

This system suits 2014–2026 Ram 2500 owners running a diesel engine with the factory OEM rear air spring setup who want 2.5" of front lift, improved on- and off-road ride quality, and externally adjustable damping without losing factory air ride functionality. It is well suited to towing, mixed on- and off-road use, and rough work-site terrain.

This system does not fit Ram 2500 2WD models, gasoline-engine Ram 2500s, or Ram 2500 trucks without factory rear air springs. The Ram 2500 Rebel receives only 0.5" of front lift with this system, not 2.5". ADAS recalibration is required after installation and is not included. The optional ICON 2" Air Ride Kit (Part #214212) for adjustable rear ride height is sold separately.

Common Questions

Does this system work on a gas-engine Ram 2500?

No. The front dual-rate coil springs in this Stage 4 system are rated specifically for diesel engine weight. The system is not compatible with gasoline-engine Ram 2500 trucks.

Will my factory air ride modes still work after installation?

Yes. ICON designed the rear components of this system to properly locate the factory airbags and associated hardware so they are not over-traveled. All factory air ride modes remain fully functional after the Stage 4 system is installed.

How much rear lift does this system provide?

This Stage 4 system is compatible with 0–2" of rear lift on Ram 2500 trucks equipped with factory rear air springs. Adjustable rear ride height from stock to 2" above stock requires the optional ICON 2" Air Ride Kit (Part #214212), sold separately.

What compression damping adjustment does this system offer?

All four shocks include ICON's CDC Valve, which provides 10 external compression damping settings ranging from soft to firm. Adjustments are made from outside the shock without tools or disassembly, allowing the driver to tune ride character for different loads or terrain.

Does installation require drive shaft modifications?

No drive shaft modifications are required for this Stage 4 system on the 2014–2026 Ram 2500 4WD Diesel. ADAS (Advanced Driver Assistance Systems) recalibration is required after installation.
