Is This for You?

This kit is for the 2013–2018 Ram 3500 4WD diesel owner who wants 6 inches of lift via a leaf spring system with a 6-bolt indexing ring for driveline correction — at the FOX 2.0 price point. This is the DS-generation Ram 3500 diesel platform. If you have a 2019 or newer Ram 3500, stop here — that is the DT platform and requires a different kit. If you want FOX 2.5 PE shocks instead, see SKU 2104FPE.

The Result

6 inches of lift on the DS-generation Ram 3500 diesel platform via replacement leaf springs and a 6-bolt indexing ring for driveline correction. The truck clears larger tires, sits aggressive, and maintains corrected driveline geometry at 6-inch lift height. FOX 2.0 shocks deliver consistent damping at this lift height.

Installation & Fabrication Notes

• Professional installation required: 6-inch leaf spring lift on a diesel platform requires a qualified suspension shop.
• Alignment mandatory: Full front-end alignment required after installation. Do not drive on public roads before alignment is completed.
• Driveline inspection mandatory: At 6-inch lift, inspect driveshaft angles and U-joint operating angles after installation. The 6-bolt indexing ring corrects pinion angle — confirm proper installation per BDS instructions.
• Torque specs: Torque all fasteners to BDS specification per included installation instructions. Do not estimate.

Wheel & Tire Fitment

At 6-inch lift on the Ram 3500 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.

Installation Warning

Application-specific. Confirm 2013–2018 Ram 3500 4WD diesel before ordering. Does NOT fit 2019+ Ram 3500 — different platform. Does not fit gas, 2WD, or Ram 2500. Driveline inspection mandatory at 6-inch lift. This product is non-returnable once installed.
