BDS 5.5-Inch 4-Link Lift Kit | Rear Air Ride | FOX 2.0 Shocks | Ram 2500 4WD Gas 2019–2026 | SKU: 1739FS

Is This for You?

This kit is for the 2019–2026 Ram 2500 4WD gas owner with factory rear air ride suspension who wants 5.5 inches of front lift via a 4-link conversion with FOX 2.0 damping. This kit is air ride-specific — it includes the brackets required to integrate with the factory rear air ride system and preserve load-leveling functionality. If your Ram 2500 does NOT have factory rear air ride, order SKU 1681FS (5.5-inch radius arm, FOX 2.0) or SKU 1699FS (4-inch radius arm, FOX 2.0) instead. If you have a 2014–2018 Ram 2500 with air ride, stop here — that is the DS platform, order SKU 1630FS.

The Result

5.5 inches of front lift via a 4-link conversion on the DT-generation Ram 2500 gas platform — corrected geometry, eliminated radius arm bind, improved articulation, and FOX 2.0 damping. The factory rear air ride system is retained and integrated with air ride-specific brackets. The truck sits aggressive, clears larger tires, and maintains consistent geometry under towing and hauling loads.

Wheel & Tire Fitment

At 5.5-inch front lift on the Ram 2500 gas platform, typical fitment runs 35–37-inch tires depending on wheel offset and backspacing. Confirm maximum tire diameter and wheel specs with your wheel/tire supplier before ordering.

Without air ride — order SKU 1681FS or 1699FS. 2014–2018 Ram 2500 with air ride — order SKU 1630FS. Does not fit diesel, 2WD, or Ram 3500. Air ride system verification mandatory after installation. This product is non-returnable once installed.
