Air Bag Suspension Kit, Air Springs Suspension Bag Kit Compatible With 2003-2013 Dodge Ram 2500 4WD, 2003-2018 Dodge Ram 3500 4WD, 5000 Lbs Loading, 5 To 100 PSI

Stop your RAM from squatting, swaying, and bottoming out the moment you hook up a trailer or stack the bed. This bolt-on air bag suspension kit is purpose-built for owners of the 2003-2013 Dodge RAM 2500 4WD and 2003-2018 Dodge RAM 3500 4WD who demand real load support without a trip to a fabrication shop. With a 5,000 lb rated capacity per pair and pressure fully adjustable from 5 to 100 PSI, this kit turns a heavily loaded half-ton into a planted, confidence-inspiring machine — in an afternoon. Compatibility This air spring suspension kit is precision-engineered for the 2003-2013 Dodge RAM 2500 4WD and the 2003-2018 Dodge RAM 3500 4WD. Whether you're running a Cummins diesel or a Hemi gas engine, the fitment is based on the rear axle and frame geometry common across these model years and the 4WD drivetrain configuration. This kit is ideal for owners who regularly tow fifth-wheel campers, gooseneck trailers, horse haulers, toy haulers, or heavy equipment, as well as commercial fleet operators who run these trucks at or near maximum payload ratings. Always verify your drivetrain (4WD) and model year before ordering. This kit is not rated for 2WD variants without independent confirmation of fitment — contact support if you are unsure. Key Benefits • Eliminates Dangerous Squat and Sway: The air bags mount between the rear axle and the frame, providing a progressive, load-responsive cushion that keeps your truck level and stable regardless of payload weight. • 5,000 Lb Load Capacity: Rated at 5,000 lbs (2,268 kg) per pair, these air springs deliver the backbone your RAM 2500 or 3500 needs when leaf springs alone are no longer enough to manage maximum payload or tongue weight. • Fully Adjustable 5–100 PSI Pressure Range: Run as low as 5 PSI when driving unladen for a smooth highway ride, then pump up to 100 PSI when hauling your heaviest loads. Adjust in minutes using any standard Schrader-compatible air compressor or tire inflator you already own. • No Drilling, No Fabrication: This is a true bolt-on upgrade. All mounting points use existing factory hardware locations, so installation requires only basic hand tools and no irreversible modifications to your truck. • Prevents Metal-to-Metal Bottoming Out: Positioned between the axle and frame, the air springs act as a cushioning buffer that stops the catastrophic metal-to-metal contact that damages frames, axles, and suspension components over time. • Works Alongside Factory Suspension: These air helper springs are designed to complement — not replace — your factory leaf springs. The result is a combined system that performs better under load while maintaining OE ride quality when the truck is empty. Technical Specifications • Load Capacity: 5,000 lbs (2,268 kg) per pair • Operating Pressure Range: 5 PSI (unladen / minimum) to 100 PSI (maximum load) • Valve Type: Schrader valve — standard tire-style, compatible with all air compressors, hand pumps, and onboard air systems • Fitment: 2003-2013 Dodge RAM 2500 4WD and 2003-2018 Dodge RAM 3500 4WD • Mount Style: Bolt-on, utilizes existing factory hardware locations — no drilling required • Spring Position: Rear axle-to-frame, between leaf spring pack and frame rail • Included Hardware: All mounting brackets, air fittings, and fasteners required for installation • Certifications / Rating: Designed for heavy-duty towing, hauling, and commercial fleet use Materials & Build Quality These air bags are constructed from heavy-duty reinforced rubber engineered to withstand the punishing cycles of repeated inflation, deflation, compression, and rebound that a working truck demands. The outer shell uses a high-tensile rubber compound resistant to road debris, ozone, UV exposure, and the thermal extremes that accompany commercial use across North American climates — from sub-zero Montana winters to high-desert Arizona summers. Internal reinforcement layers resist ballooning and ensure consistent, predictable spring rates across the full 5–100 PSI operating range. The mounting hardware is steel, treated to resist corrosion from road salt, moisture, and the underbody environment typical of heavy-use trucks. The Schrader valves are brass-core units identical in design to standard tire valves, ensuring long service life and universal compatibility with inflation equipment. Every component in this kit is selected for working-truck durability, not just fit-and-finish. Installation Guide Installing this air bag suspension kit is a straightforward job for any DIYer comfortable with basic hand tools. Budget approximately two to three hours for a first-time install. You will need a floor jack, jack stands, a basic socket set (metric and SAE), a torque wrench, and an air compressor or hand pump. Step 1 – Safety First: Park on a level surface, engage the parking brake, and chock the front wheels. Raise the rear of the truck with a floor jack and secure it on jack stands rated for the vehicle's weight. Step 2 – Measure and Mark: With the suspension hanging freely, identify the mounting locations between the rear axle and the frame rail on each side. Consult the included instruction sheet for your specific model year's bracket positioning. Step 3 – Mount the Lower Brackets: Bolt the lower mounting brackets to the axle using the provided hardware. Do not fully torque yet — allow for adjustment. Step 4 – Position the Air Bags: Seat the air bags into the lower brackets, then raise the axle slightly with the floor jack to compress the bag into position against the frame rail mounting point. Step 5 – Mount the Upper Brackets: Secure the upper brackets to the frame using the factory bolt locations. Torque all hardware to spec per the included instructions. Step 6 – Route the Air Lines: Connect the air lines to the Schrader valves on each air spring. Route lines away from exhaust components and secure with provided clamps. Step 7 – Inflate and Test: Inflate each bag to 20–30 PSI, lower the truck, and inspect all connections for leaks. Road test and adjust pressure to your desired load setting.
