BDS 5.5-Inch Radius Arm Lift Kit | Rear Air Ride | FOX 2.0 Shocks | Ram 3500 4WD Gas 2019–2026 | SKU: 1726FS

Is This for You?

This kit is for the 2019–2026 Ram 3500 4WD gas owner with factory rear air ride suspension who wants 5.5 inches of front lift via radius arm upgrade 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 3500 does NOT have factory rear air ride, order SKU 1686FPE (no overload, FOX 2.5 PE) or SKU 1687FPE (with overload, FOX 2.5 PE). If you want 4 inches of lift with air ride instead of 5.5 inches, see SKU 1723FS. If your Ram 3500 is diesel with air ride, see SKU 1724FS.

The Result

5.5 inches of front lift with corrected caster, reduced bushing bind, and FOX 2.0 damping on the Ram 3500 gas platform — with factory rear air ride integration. The factory load-leveling function is preserved at lifted height via air ride-specific rear 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 3500 gas platform, typical fitment runs 35–38-inch tires depending on wheel offset and backspacing. Confirm maximum tire diameter and wheel specs with your wheel/tire supplier before ordering.

Installation Warning

Does not fit 2WD or 2018 and earlier Ram 3500. Air ride system verification mandatory after installation. This product is non-returnable once installed.
