BDS 6-Inch Radius Arm Lift Kit | FOX 2.0 Shocks | Ram 2500 4WD Diesel 2014–2018 | SKU: 2100FS

Is This for You?

This kit is for the 2014–2018 Ram 2500 4WD diesel owner who wants maximum front lift — 6 inches — at the FOX 2.0 price point. This is the DS-generation Ram 2500 diesel platform. If you have a 2019 or newer Ram 2500, stop here — that is the DT platform, order SKU 1680FS. If you want FOX 2.5 PE shocks instead of FOX 2.0, see SKU 2100FPE. If you need 4 inches instead of 6, see SKU 1762FPE (FOX 2.5 PE) or SKU 1762FS (FOX 2.0).

The Result

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

Wheel & Tire Fitment

At 6-inch front lift on the Ram 2500 diesel platform, typical fitment runs 37–40-inch tires depending on wheel offset and backspacing. Confirm maximum tire diameter and wheel specs with your wheel/tire supplier before ordering. Oversized tires may require trimming or additional modifications at this lift height.
