BDS 6-Inch Radius Arm Lift Kit | Rear Air Ride | 6-Bolt Indexing Ring | FOX 2.0 Shocks | Ram 3500 4WD Diesel 2019-2024

BDS 6-Inch Radius Arm Lift Kit | Rear Air Ride | 6-Bolt Indexing Ring | FOX 2.0 Performance Series Shocks | Ram 3500 4WD Diesel 2019–2024 | With Factory Rear Air Ride | SKU: BDS1724FS

The BDS 6-Inch Radius Arm Lift Kit (SKU: BDS1724FS) is a complete 6-inch front lift system for 2019–2024 Ram 3500 4WD diesel models equipped with the factory rear air ride suspension system, paired with FOX 2.0 Performance Series shocks. This kit includes two components specific to the 2019–2024 Ram 3500 diesel platform: rear air ride-specific brackets that preserve factory load-leveling functionality at lifted height, and a 6-bolt indexing ring that corrects driveline geometry at 6-inch lift height. If your Ram 3500 does not have factory rear air ride, order BDS1682FPE or BDS1683FPE instead. Using the standard kit on a Ram 3500 with factory air ride will result in rear suspension incompatibility.

Verified Fitment (OFAS Standard)

• Ram 3500 4WD Diesel: 2019–2024 — with factory rear air ride suspension, 6-bolt front axle

Does NOT fit: Ram 3500 without factory rear air ride — order BDS1682FPE (no overload leaf) or BDS1683FPE (with overload leaf) for standard suspension. Does not fit Ram 3500 gas. Does not fit Ram 3500 2WD. Does not fit Ram 3500 2025 or newer — different platform. Does not fit Ram 3500 2018 or earlier — order BDS2106FS for 2013–2018 Ram 3500 diesel with air ride. Does not fit Ram 2500. Confirm model year, drivetrain, engine, rear suspension type, and axle bolt pattern before ordering.

Two Platform-Specific Components — Both Required for 2019–2024 Ram 3500 Diesel Air Ride

• Rear air ride-specific brackets: The factory rear air ride suspension system on select 2019–2024 Ram 3500 models uses air bags and load-leveling components that require specific lift kit brackets to function correctly at lifted height. This kit includes those brackets — preserving load-leveling functionality. The standard 6-inch kits (BDS1682FPE / BDS1683FPE) do not include air ride brackets and are not compatible with the factory air ride system.
• 6-bolt indexing ring: The 2019–2024 Ram 3500 diesel uses a 6-bolt front axle. At 6-inch lift height, the driveline geometry requires correction via a 6-bolt indexing ring to maintain proper U-joint operating angles and prevent driveline vibration. This component is specific to the 2019–2024 Ram 3500 diesel platform at 6-inch lift height.

Factory Rear Air Ride — Critical Fitment Gate

Confirm whether your Ram 3500 has the factory rear air ride suspension before ordering. Contact OFAS at 903-347-3875 to verify your configuration.

• With factory rear air ride (BDS1724FS, this listing): Includes air ride brackets + 6-bolt indexing ring — for 2019–2024 Ram 3500 4WD diesel with air ride
• Without factory rear air ride — with overload leaf (BDS1683FPE): Standard 6-inch radius arm kit for 2019–2024 Ram 3500 4WD diesel with overload leaf
• Without factory rear air ride — no overload leaf (BDS1682FPE): Standard 6-inch radius arm kit for 2019–2024 Ram 3500 4WD diesel without overload leaf
• 2013–2018 Ram 3500 diesel with air ride (BDS2106FS): Previous generation air ride kit — different platform, different components

Two Critical Fitment Gates

• 4WD only: Does not fit 2WD models.
• Diesel only: Diesel-tuned coil springs for diesel front-end weight. Does not fit gas models.

Radius Arm Upgrade at 6-Inch Lift — Why It Matters

• Heavy-duty BDS radius arms: Replace factory radius arms with BDS-engineered heavy-duty arms for 6-inch lift height, larger tires, and diesel work truck loads
• Caster correction: Maintains proper caster angle at 6-inch lift height
• Reduced bushing bind: Improved arm geometry reduces bind under articulation and load
• Track bar correction: Maintains proper axle centering at lifted height

FOX 2.0 Performance Series Shocks

• Improved damping: Significantly improved damping over factory shocks at lifted height
• Heat resistance: 2.0-inch shock body for improved heat dissipation during extended towing
• Ride quality: Tuned for Ram 3500 4WD diesel platform
• FOX warranty: 1-year limited warranty

Installation Notes

• Professional installation required: 6-inch radius arm lift with air ride integration and driveline correction requires professional installation by a qualified suspension shop familiar with air ride systems and driveline geometry.
• Alignment mandatory: Full front-end alignment required after installation. Do not drive on public roads before alignment is completed.
• Air ride system verification: Verify factory air ride load-leveling function after installation. Contact OFAS at 903-347-3875 if air ride does not function correctly after installation.
• Driveline inspection: Verify U-joint operating angles and driveline vibration after installation. The 6-bolt indexing ring corrects driveline geometry — confirm proper installation per BDS instructions.
• Torque specs: All fasteners must be torqued to BDS specifications per installation instructions.
• Tire sizing: Contact OFAS at 903-347-3875 to confirm maximum tire size before ordering wheels and tires.

Installation Warning

Professional installation required. Alignment mandatory. Air ride system verification required after installation. Driveline inspection required — confirm 6-bolt indexing ring installation per BDS instructions. Does not fit standard suspension — order BDS1682FPE or BDS1683FPE for non-air-ride. Does not fit gas, 2WD, 2025 and newer, or 2018 and earlier Ram 3500.

Have you confirmed your Ram 3500 is a 2019–2024 4WD diesel with factory rear air ride and 6-bolt front axle — no air ride? Order BDS1682FPE or BDS1683FPE. 2013–2018 with air ride? Order BDS2106FS. Contact OFAS at 903-347-3875 to verify your configuration before ordering.
