ICON 2014-2026 Ram 2500 4WD Diesel 4.5" Lift Stage 1 Suspension System

The ICON Stage 1 Suspension System for the 2014–2026 Ram 2500 4WD (diesel, factory rear air suspension) delivers 4.5 inches of front lift and 3.75 inches of rear lift using vehicle-specific ICON 2.0 Aluminum Series shocks, ICON-engineered dual rate front coil springs, an adjustable front track bar, radius arm drop brackets, and fabricated rear air bag spacers that retain the factory rear air ride system and its ride-height adjustability.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Balanced Lift Without Sacrificing Tow Capability

The dual rate front coil springs are rated specifically for diesel engine weight, so the added mass of a diesel powertrain is accounted for in the spring rate rather than approximated. This system is engineered to maintain factory tow capacity, a meaningful distinction for a truck used to pull a trailer or fifth wheel regularly. The level front-to-rear stance also keeps trailer hitch height consistent with the stock geometry buyers depend on.

Factory Rear Air Ride Stays Intact

The fabricated rear air bag spacers and sensor linkages are designed to work with the OEM rear air suspension rather than replace it. The factory ride-height adjustment function continues to operate after installation. For Ram 2500 owners who rely on that system for load leveling, this matters: a kit that deletes the air ride removes a feature that cost thousands from the factory and cannot easily be reinstated.

Geometry Corrected, Not Just Lifted

The adjustable front track bar with PTFE-lined spherical bearings realigns the front axle after the lift and eliminates the bushing deflection that causes vague on-center steering feel on lifted trucks. Precision CNC laser-cut radius arm drop brackets correct the radius arm angle, preventing the accelerated wear and handling compromise that follows a lift done without geometry correction. The front and rear 2.0 Aluminum Series shocks are tuned specifically for this application and are fully serviceable.

Features

• 4.5" front lift / 3.75" rear lift: dual rate coil springs rated for diesel engine weight; 2.5" front lift on Ram 2500 Rebel submodel
• 2.0 Aluminum Series shocks: vehicle-specific front and rear tuning; fully serviceable
• Adjustable front track bar: PTFE-lined spherical bearings eliminate bushing deflection and realign front axle
• Radius arm drop brackets: CNC laser-cut fabricated steel; correct suspension geometry post-lift
• Rear air ride retained: fabricated air bag spacers and sensor linkages preserve OEM air spring function and ride-height adjustability
• Tire clearance: accommodates up to 37x12.50" tires; larger sizes may require fender trimming

Specifications

Who This Is For and Isn't

This system suits 2014–2026 Ram 2500 4WD owners running a diesel engine and factory rear air suspension who want a level 4.5" lift, geometry-corrected handling, and the ability to run up to 37" tires without giving up tow capacity or the OEM air ride function.

This system does not fit 2WD Ram 2500 models, gasoline-engine Ram 2500 models, or any Ram 2500 not equipped with the factory rear air suspension. The Ram 2500 Rebel receives 2.5" of front lift rather than 4.5". Vehicles with two-piece driveshafts require a separate carrier shim kit (ICON 214211, sold separately). 2019–2026 Ram 2500 and 3500 models require a separate aftermarket high-angle front driveshaft (ICON 212511 or 212512, sold separately) to prevent driveshaft bind. ADAS recalibration is required after installation. This system is not compatible with aftermarket trackbars not designed for this application.

Common Questions

Does this system work with the factory rear air suspension, or does it replace it?

The ICON Stage 1 system for the 2014–2026 Ram 2500 retains the factory rear air springs. The fabricated rear air bag spacers and sensor linkages are designed to work alongside the OEM components, and the factory ride-height adjustment function continues to operate after installation.

Will this fit a Ram 2500 with a gasoline engine?

No. The front coil springs in this Stage 1 system are rated specifically for diesel engine weight. This kit is not compatible with gasoline-engine Ram 2500 models; a different spring rate would be required for a gas-powered truck.

What additional parts might be needed beyond what is in the box?

Ram 2500 trucks with two-piece driveshafts require a separate carrier shim kit (ICON part 214211). On 2019–2026 Ram 2500 and 3500 models, an aftermarket high-angle front driveshaft (ICON 212511 or 212512) is required to prevent driveshaft bind. ADAS recalibration is also required after installation and is not included.

What tire size will fit after installing this system?

The ICON Stage 1 system for the 2014–2026 Ram 2500 accommodates tires up to 37x12.50" in diameter. Larger tires may fit but will require fender trimming and additional modifications.

Does the lift height differ on the Ram 2500 Rebel?

Yes. This Stage 1 system provides 4.5 inches of front lift on most Ram 2500 submodels, but delivers 2.5 inches of front lift on the Ram 2500 Rebel due to differences in the Rebel's factory suspension geometry.
