BDS 5.5-Inch Radius Arm Lift Kit | FOX 2.0 Shocks | Ram 2500 4WD Gas 2019–2026 | SKU: 1681FS

Is This for You?

This kit is for the 2019–2026 Ram 2500 4WD gas owner who wants 5.5 inches of front lift at the FOX 2.0 price point. If you want 4 inches instead of 5.5, see SKU 1699FS (FOX 2.0) or SKU 1699FPE (FOX 2.5 PE). If you want FOX 2.5 PE shocks with external reservoir at 5.5 inches, contact OFAS — that variant may be available. If your Ram 2500 has factory rear air ride, stop here — order SKU 1739FS instead.

The Result

5.5 inches of front lift with corrected caster, reduced bushing bind, and FOX 2.0 damping on the DT-generation Ram 2500 gas platform. The truck clears larger tires, sits aggressive, and maintains consistent geometry under towing and hauling loads. FOX 2.0 shocks deliver improved damping over factory at this lift height.
