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\".\u003c\/p\u003e\n\u003cp class=\"product-shipping-note\"\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground.

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.\u003c\/p\u003e\n\n\u003ch2\u003eDual-Rate Springs and Adjustable Track Bar\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch2\u003eAir Ride Compatibility Preserved\u003c\/h2\u003e\n\u003cp\u003eICON 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.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.5 Aluminum Series Reservoir Shocks:\u003c\/strong\u003e front and rear, fully serviceable, with CDCV for 10 compression damping settings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiesel-Rated Dual-Rate Front Coil Springs:\u003c\/strong\u003e match-tuned to the included shocks for this application\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable Front Track Bar:\u003c\/strong\u003e PTFE-lined spherical bearings, centers front axle after lift installation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFactory Air Ride Preserved:\u003c\/strong\u003e rear components designed to maintain full OEM air ride mode functionality\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNo Drive Shaft Modifications Required:\u003c\/strong\u003e installs without driveline changes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eADAS Recalibration Required:\u003c\/strong\u003e Advanced Driver Assistance Systems must be recalibrated after installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVehicle Fitment\u003c\/td\u003e\n      \u003ctd\u003e2014–2026 Ram 2500 4WD, Diesel, OEM Rear Air Spring equipped\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Lift\u003c\/td\u003e\n      \u003ctd\u003e2.5\" (0.5\" on Ram 2500 Rebel)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Lift Compatibility\u003c\/td\u003e\n      \u003ctd\u003eCompatible with 0–2\" rear lift on factory air spring trucks\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Shocks\u003c\/td\u003e\n      \u003ctd\u003eICON 2.5 Aluminum Series reservoir shocks with CDCV (Part #217802CP, qty 1 pair)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Shocks\u003c\/td\u003e\n      \u003ctd\u003eICON 2.5 Aluminum Series air ride rear shocks with CDCV (Part #217708CP, qty 1 pair)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Springs\u003c\/td\u003e\n      \u003ctd\u003eDual-rate coil spring kit, diesel-rated (Part #214200, qty 1)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Track Bar\u003c\/td\u003e\n      \u003ctd\u003eAdjustable, PTFE-lined spherical bearings (Part #214214, qty 1)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock Diameter\u003c\/td\u003e\n      \u003ctd\u003e2.5\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOEM Wheel Fitment\u003c\/td\u003e\n      \u003ctd\u003eYes\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Aftermarket Wheels\u003c\/td\u003e\n      \u003ctd\u003e17x8.5\" (5.25\" BS \/ 13mm offset), 18x9\" (5.50\" BS \/ 12mm offset), 20x9\" (5.50\" BS \/ 12mm offset)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Max Tire Size\u003c\/td\u003e\n      \u003ctd\u003e35\" x 12.50\" (larger tires may require fender trimming)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e127 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eK212544A\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThis 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.
