ICON 2014-2026 Ram 2500 4WD Diesel Stage 2 Suspension System 4.5" Lift

The ICON Stage 2 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 through a complete set of ICON-engineered components: coil springs, 2.5 Aluminum Series remote reservoir shocks, adjustable track bar, radius arm drop brackets, rear air bag spacers, and all installation hardware. The Ram 2500 Rebel submodel receives 2.5 inches of front lift rather than 4.5 inches.

Dual-Rate Springs and Remote Reservoir Shocks

ICON's 4.5-inch dual-rate front coil springs are rated specifically for diesel engine weight, so spring rate matches the actual load the front axle carries rather than a generic heavy-duty estimate. The vehicle-specific 2.5 Aluminum Series remote reservoir shocks front and rear are tuned to this truck's mass and suspension geometry, not adapted from a lighter platform. The result is a balanced ride from front to rear whether the Ram is loaded, towing, or running empty on a dirt road.

Geometry Correction That Preserves Towing Capacity

Lifting a solid-axle truck without correcting caster and pinion angle trades ride quality and handling for lift height. The Stage 2 system addresses this with precision CNC laser-cut radius arm drop brackets that restore suspension geometry at the new ride height, and an adjustable front track bar with PTFE-lined spherical bearings that realigns the front axle and eliminates the bushing deflection that causes vague steering feel. ICON states towing capacity is unchanged from stock.

Factory Rear Air Suspension Retained

The fabricated rear air bag spacers and sensor linkages in this kit are designed to work with the Ram 2500's factory rear air ride system rather than replace it. Rear ride height adjustability through the OEM controls is preserved, and the factory air springs remain in place. This kit is compatible only with Ram 2500 models already equipped with factory rear air suspension; it does not add air suspension to trucks that lack it.

Features

Who This Is For and Isn't

This system suits 2014–2026 Ram 2500 4WD owners running a diesel engine with factory rear air suspension who want a 4.5-inch front lift with corrected geometry, retained air ride functionality, and balanced on-road and off-road performance without sacrificing towing capacity.

This kit does not fit Ram 2500 gas engine models, 2WD models, or any Ram 2500 not equipped with factory rear air suspension. Ram 2500 Rebel owners receive 2.5 inches of front lift, not 4.5 inches. Trucks with two-piece driveshafts require an additional carrier shim kit (ICON part 214211, sold separately). 2019–2026 Ram 2500 and 3500 models require an aftermarket high-angle front driveshaft (ICON part 212511 or 212512, sold separately) to prevent driveline bind. Advanced Driver Assistance Systems (ADAS) require recalibration after installation. This kit is not confirmed compatible with aftermarket track bars from other brands.

Common Questions

Does this kit work on gas-engine Ram 2500 trucks?

No. The ICON Stage 2 system for the 2014–2026 Ram 2500 includes dual-rate front coil springs rated specifically for diesel engine weight. The kit is not compatible with gas-engine Ram 2500 models.

Does the factory rear air suspension still work after installing this kit?

Yes. The fabricated rear air bag spacers and sensor linkages in this Stage 2 system are designed to retain the factory rear air spring function and OEM ride height adjustability. The kit is compatible only with trucks already equipped with factory rear air suspension; it does not add air suspension to trucks that lack it.

Are there additional parts required beyond what is in the box?

Trucks with two-piece driveshafts require ICON carrier shim kit 214211, sold separately. 2019–2026 Ram 2500 and 3500 models require an aftermarket high-angle front driveshaft (ICON part 212511 or 212512, sold separately). ADAS recalibration is required after installation and is not included. Compatibility with aftermarket track bars from other brands is not confirmed.

What is the lift height on a Ram 2500 Rebel?

On the Ram 2500 Rebel submodel, this ICON Stage 2 system provides 2.5 inches of front lift rather than the 4.5 inches delivered on most other Ram 2500 submodels. Rear lift is 3.75 inches on all compatible models.

Are the shocks rebuildable?

Yes. The 2.5 Aluminum Series remote reservoir shocks included in this Stage 2 system are fully serviceable, meaning they can be rebuilt or revalved rather than replaced outright when service is needed.
