BDS 5.5-Inch Lift Kit | Rear Air Ride | FOX 2.0 Shocks | Ram 2500 4WD Gas 2014–2018 | SKU: 1630FS

Is This for You?

This kit is for the 2014–2018 Ram 2500 4WD gas owner with factory rear air ride suspension who wants 5.5 inches of front lift with FOX 2.0 damping. This is the DS-generation Ram 2500 gas platform. If your Ram 2500 does NOT have factory rear air ride, a different kit is required. If you have a 2019 or newer Ram 2500 with air ride, stop here — that is the DT platform, order SKU 1739FS instead.

The Result

5.5 inches of front lift with geometry-correct radius arm brackets, FOX 2.0 damping, and factory rear air ride integration on the DS-generation Ram 2500 gas platform. The factory load-leveling function is preserved at lifted height via air ride-specific rear brackets. The truck sits level and aggressive, clears larger tires, and maintains consistent geometry under towing and hauling loads.

Installation & Fabrication Notes

• Professional installation required: Suspension lift with air ride integration requires a qualified suspension shop familiar with Ram air ride systems.
• 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. If air ride does not function correctly, do not drive — contact your installer.
• Torque specs: Torque all fasteners to BDS specification per included installation instructions. Do not estimate.
• Break-in period: Allow FOX shocks to break in per FOX recommendations before aggressive off-road use.

Wheel & Tire Fitment

At 5.5-inch front lift on the Ram 2500 gas platform, typical fitment runs 35–37-inch tires depending on wheel offset and backspacing. Confirm maximum tire diameter and wheel specs with your wheel/tire supplier before ordering.

Installation Warning

Application-specific. Confirm 2014–2018 Ram 2500 4WD gas WITH factory rear air ride before ordering. Without air ride — different kit required. 2019+ Ram 2500 with air ride — order SKU 1739FS. Does not fit diesel, 2WD, or Ram 3500. Air ride system verification mandatory after installation. This product is non-returnable once installed.

Does your Ram 2500 have factory rear air ride suspension? Is it a 2014–2018 DS-generation or 2019+ DT-generation? Gas or diesel? Those details determine which kit ships.
