Is This for You?

This kit is for the 2019–2026 Ram 3500 4WD diesel owner with factory rear air ride suspension who wants 6 inches of front lift via radius arm upgrade with FOX 2.0 damping and a 6-bolt indexing ring for driveline correction. 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 1683FPE (with overload leaf, FOX 2.5 PE) or SKU 1682FPE (no overload leaf, FOX 2.5 PE). If your Ram 3500 is gas with air ride, see SKU 1726FS.

The Result

6 inches of front lift with corrected caster, reduced bushing bind, driveline correction via 6-bolt indexing ring, and FOX 2.0 damping on the Ram 3500 diesel 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 diesel towing loads.

Installation & Fabrication Notes

• Professional installation required: 6-inch radius arm lift with air ride integration on a diesel platform requires a qualified suspension shop experienced with Ram air ride systems.
• 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.
• Air ride system verification: Verify factory air ride load-leveling function after installation. If air ride does not function correctly, do not drive — contact your installer.
• 6-bolt axle confirmation: Confirm 6-bolt front axle configuration before ordering.
• Torque specs: Torque all fasteners to BDS specification per included installation instructions. Do not estimate.

Wheel & Tire Fitment

At 6-inch front 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 2019–2026 Ram 3500 4WD diesel WITH factory rear air ride and 6-bolt front axle before ordering. Without air ride — order SKU 1683FPE or 1682FPE. Gas with air ride — order SKU 1726FS. Does not fit 2WD or 2018 and earlier Ram 3500. Driveline inspection mandatory at 6-inch lift. Air ride system verification mandatory after installation. This product is non-returnable once installed.
