ICON Vehicle Dynamics 2014-2026 Ram 2500 4WD Diesel 2.5" Lift Stage 3 Suspension System

The ICON Vehicle Dynamics Stage 3 Suspension System for 2014–2026 Ram 2500 4WD Diesel trucks with OEM rear air springs delivers 2.5 inches of front lift on most Ram 2500 submodels (0.5 inches on the Rebel) through a matched set of dual-rate front coil springs, 2.5 Aluminum Series reservoir shocks front and rear, and an adjustable front track bar, all engineered and tuned as a single package. This system is built specifically for diesel-engine, 4WD Ram 2500s equipped with factory rear air springs and is compatible with 0–2 inches of rear lift on that air-spring platform.

Reservoir Shocks Built for Sustained Performance

The 2.5 Aluminum Series reservoir shocks included front and rear separate the fluid and gas charge into a dedicated reservoir, which increases the volume available for heat dissipation during extended hard use. The practical result is more consistent damping over rough construction-site terrain, washboard dirt roads, and loaded towing runs: situations where a standard shock heats up and fades. All four shocks are fully serviceable, so the system can be rebuilt and revalved rather than replaced outright.

Adjustable Track Bar for Axle Centering and Rigidity

The front adjustable track bar uses PTFE-lined spherical FK bearings in place of the factory rubber bushings. Spherical bearings eliminate the deflection and compliance that rubber joints introduce under lateral load, tightening steering response and reducing body roll. The adjustable length lets the installer center the front axle under the truck after the lift, a step that fixed-length bars cannot perform and that matters for tire clearance and straight-line tracking.

Air-Ride Compatible Design

Rather than bypassing the Ram 2500's factory air-ride system, ICON engineered this kit to locate the airbags and associated components so they are not over-traveled or damaged at ride height. All factory air-ride modes remain fully functional after installation. The optional ICON 2" Air Ride Kit (Part #214212, sold separately) adds end-user adjustability of rear ride height from stock up to 2 inches over stock.

Features

• Dual-rate front coil springs: rated specifically for diesel-engine Ram 2500s; matched and tuned to the included shocks
• 2.5 Aluminum Series reservoir shocks (front and rear): fully serviceable; reservoir design maintains consistent damping during heavy use
• Adjustable front track bar: PTFE-lined spherical FK bearings; length-adjustable to center the front axle after lift
• Factory air-ride compatibility: components locate OEM airbags correctly; all factory air-ride modes retained
• No driveshaft modifications required
• No reduction in towing capacity

Specifications

Who This Is For and Isn't

This system suits 2014–2026 Ram 2500 owners running a 4WD diesel truck with the factory rear air-spring suspension who want 2.5 inches of front lift with improved damping for towing, off-road use, and mixed on/off-road driving without losing factory air-ride functionality.

This system does not fit Ram 2500 gas-engine models, 2WD models, or Ram 2500s without OEM rear air springs. It provides only 0.5 inches of front lift on the Ram 2500 Rebel. The optional ICON 2" Air Ride Kit (Part #214212) for rear-height adjustability is sold separately and is not included. ADAS recalibration is required after installation and is not part of this kit.

Common Questions

Does this system work with the Ram 2500's factory air-ride modes?

Yes. The ICON Stage 3 system for the 2014–2026 Ram 2500 with OEM rear air springs is designed to properly locate the factory airbags so they are not over-traveled, and all factory air-ride modes remain fully functional after installation.

Does this kit fit gas-engine or 2WD Ram 2500 trucks?

No. The ICON Stage 3 system K212543A is rated for diesel-engine, 4WD Ram 2500 models only. The front coil springs are specifically tuned for the diesel engine's weight distribution and will not perform correctly on gas-engine trucks.

How much front lift does this system provide on the Ram 2500 Rebel?

On the Ram 2500 Rebel, this ICON Stage 3 system provides 0.5 inches of front lift rather than the 2.5 inches it delivers on most other Ram 2500 submodels. This difference is due to the Rebel's factory suspension geometry.

Is rear-height adjustability included in this kit?

Rear-height adjustability is not included. The system is compatible with 0–2 inches of rear lift on factory air-spring Ram 2500 trucks. The optional ICON 2" Air Ride Kit (Part #214212), which allows end-user adjustment of rear ride height from stock to 2 inches over stock, is sold separately.

Are the shocks in this system rebuildable?

Yes. All four 2.5 Aluminum Series reservoir shocks included in this Stage 3 system are fully serviceable, meaning they can be rebuilt and revalved by a qualified shop rather than replaced as a unit.
