BDS 6-Inch Radius Arm Lift Kit | Rear Air Ride | 6-Bolt Indexing Ring | FOX 2.0 Shocks | Ram 3500 4WD Diesel 2019–2024 | SKU: 1724FS

The BDS 1724FS is a 6-inch radius arm front lift kit with FOX 2.0 Performance Series shocks for the 2019–2024 Ram 3500 4WD diesel with factory rear air ride and a 6-bolt front axle. Two components in this kit are specific to this exact configuration: rear air ride brackets that preserve factory load-leveling function at lifted height, and a 6-bolt indexing ring that corrects driveline geometry at 6-inch lift. Neither component is included in the standard 6-inch kits — and without both installed correctly, the air ride system will not operate at lifted height and the driveline will run outside its designed U-joint angle range.

Five confirmations required before this kit applies to your truck.

First — rear suspension: factory rear air ride only. Without it, order 1682FPE (no overload leaf) or 1683FPE (with overload leaf).

Second — axle: 6-bolt front axle required. The indexing ring in this kit is specific to the 6-bolt configuration.

Third — engine: diesel only. Diesel-tuned coil springs are not correct for the gas platform.

Fourth — year: 2019–2024 only. The 2025 and newer Ram 3500 is a different platform. The 2013–2018 Ram 3500 with air ride requires 2106FS.

Fifth — drivetrain: 4WD only.

How to Confirm Factory Rear Air Ride on Your Ram 3500

Check your window sticker or build sheet for "Rear Air Suspension" or "Active-Level Four-Corner Air Suspension." Visually, the factory air ride system uses air bags at the rear axle with an onboard compressor — distinguishable from conventional leaf springs on inspection. Text (469) 407-7538 with your VIN if you need confirmation before ordering.

Tire Fitment

At 6 inches of front lift on the 2019–2024 Ram 3500 diesel platform, typical fitment runs 37–40-inch tires depending on wheel offset and backspacing. Tires at the larger end of this range may require trimming depending on your specific cab, bed, and fender configuration. Confirm maximum tire diameter and wheel specifications with your installer before ordering wheels and tires.

Installation Notes

Professional installation is required — Ram air ride experience mandatory. A 6-inch radius arm lift with factory air ride integration and 6-bolt driveline correction requires a qualified suspension shop experienced with Ram air ride systems and driveline geometry. Do not attempt DIY installation.

Full front-end alignment is mandatory after installation. Do not drive on public roads before alignment is completed.

6-bolt front axle confirmation is mandatory before ordering. Count the lug bolts on your front axle flange — 6-bolt configuration required. Text (469) 407-7538 with your VIN to confirm before ordering.

6-bolt indexing ring installation must be verified. The ring corrects U-joint operating angles at 6-inch lift. Confirm proper installation per BDS instructions and verify driveline vibration after installation before road use.

Factory air ride system verification is mandatory after installation. Verify that the factory air ride load-leveling function operates correctly at lifted height. If it does not function correctly, do not drive — return to your installer to verify bracket installation per BDS instructions before road use.

Torque all fasteners to BDS specification. Do not estimate torque values on a diesel-weight platform.

FOX shock break-in period. Allow FOX 2.0 shocks to complete the manufacturer-recommended break-in period before aggressive off-road or heavy towing use.

The Obsidian Take

The BDS 1724FS is the only 6-inch solution for the 2019–2024 Ram 3500 diesel that keeps the factory air ride system working at lifted height while correcting the driveline geometry that 6 inches demands. The air ride brackets and the 6-bolt indexing ring are not accessories — they are prerequisites. Without the brackets, the load-leveling system is inoperable at lifted height. Without the indexing ring, the driveline vibrates and the U-joints wear under towing load. Both are in this kit. Neither is in the standard 1682FPE or 1683FPE.

If your Ram 3500 does not have factory rear air ride, this kit installs hardware with nothing to connect to — order 1682FPE or 1683FPE based on your overload leaf configuration. If your Ram 3500 is a 2025 or newer, this kit does not apply. If it is a 2013–2018 DS platform with air ride, order 2106FS.

Five prerequisites confirmed — the 1724FS is the complete, platform-correct solution for the 2019–2024 Ram 3500 diesel that tows heavy, rides level, and needs every component of that capability intact at 6 inches of lift.

Common Questions

How do I confirm my Ram 3500 has factory rear air ride?
Check your window sticker or build sheet for "Rear Air Suspension" or "Active-Level Four-Corner Air Suspension." Text (469) 407-7538 with your VIN and we will confirm before your order ships.

How do I confirm my Ram 3500 has a 6-bolt front axle?
Count the lug bolts on your front axle flange. Text (469) 407-7538 with your VIN if you need confirmation before ordering.

What does the 6-bolt indexing ring do?
It corrects the front axle pinion angle at 6-inch lift height. Without it, the driveshaft U-joints operate outside their designed angle range — producing vibration and accelerating wear under towing load.

What happens if my air ride doesn't work correctly after installation?
Do not drive the truck. Return to your installer to verify the air ride brackets are installed correctly per BDS instructions before road use.

Does this kit fit my 2025 Ram 3500?
No. This kit is verified for 2019–2024 only. Text (469) 407-7538 to confirm the correct kit for a 2025 Ram 3500.

What is the difference between 1724FS and 1682FPE or 1683FPE?
1724FS is for Ram 3500 trucks with factory rear air ride — includes air ride brackets and a 6-bolt indexing ring, FOX 2.0 shocks. 1682FPE and 1683FPE are for standard suspension trucks — no air ride hardware, FOX 2.5 PE shocks.

What warranty does this kit carry?
BDS suspension components carry the BDS No-Fine-Print Warranty. FOX 2.0 shocks carry a FOX 1-year limited warranty.
