Check Price on Amazon

Air Lift’s LoadLifter 5000 for the Ford Super Duty generation uses a two-ply fabric bag that delivers up to 5,000 pounds of load-leveling force. The bracket set bolts directly to the frame rail and axle perch, eliminating the guesswork of universal-fit clamps. Each bag includes an internal jounce bumper that prevents metal-to-metal contact if the air spring loses pressure entirely.

The kit ships as a complete hardware set—brackets, u-bolts, air lines, 90-degree fittings, and a detailed install manual. Owners of 2016 F-250 diesel trucks report noticeable improvements in trailer sway control when towing fifth-wheel campers, with the rear end staying level at 30 PSI. The unloaded ride requires the lowest recommended pressure (around 5 PSI) to avoid excessive stiffness over expansion joints.

Installation averages four to six hours with hand tools, mostly due to the driver-side frame bracket requiring careful maneuvering around the diesel’s exhaust system. A separate T-fitting for dual air lines is not included, so you will need to purchase one if you want a single fill point for both bags.

This Ram 2500-specific LoadLifter 5000 shares the same 5,000-pound bag rating as the Ford version but uses a different bracket geometry that clears the Cummins diesel’s chassis layout. The two-ply fabric air springs mount above the rear axle using powder-coated steel brackets that bolt directly to existing frame holes, requiring no drilling.

Real-world users towing 16,000-pound fifth-wheel trailers report that the kit completely eliminates rear squat, improving braking stability and headlight aim. The 60-day ride satisfaction guarantee gives you room to experiment with pressure settings. Most owners with a 2018-2024 Ram 2500 find that 10-15 PSI empty keeps the ride tolerable while providing immediate support when the trailer pin weight comes down.

The included hardware lacks a single-path T-fitting, and the jounce bumper is a separate purchase for some model years. Several reviewers note that the driver-side bump stop removal requires cutting with a grinder, adding roughly 30 minutes to the install if you do not have an impact wrench ready.

Firestone’s Red Label series is built around a 150 PSI max operating pressure, giving these bags a 7,500-pound load-leveling ceiling—50 percent higher than the typical 5,000-pound kit. The no-drill mounting assembly is cast specifically for GM 2500 and 3500 HD trucks, using existing frame holes on both the 2011-2026 model range.

The air springs themselves are double-convoluted with a proprietary rubber compound that resists ozone cracking and pinch-flat damage. Owners of 2019 Silverado 3500 utility beds report that the bags eliminated bottoming out entirely on mountain gravel roads, even with a fully loaded service body. The included air lines and valve stems use standard 1/4-inch NPT fittings, making aftermarket compressor integration straightforward.

The 90-degree air fittings are short, which makes threading them into tight spaces near the frame rail a patience-testing task. Firestone provides a two-year manufacturer warranty, shorter than the lifetime coverage offered by some competitors, but the higher load capacity justifies the shorter term for heavy-towing use.

The WirelessAir+ EZ Mount is not a bag kit—it is the on-board compressor and control system that lets you adjust any brand of air springs wirelessly. The 2nd generation unit packs a 120 PSI, 1.03 CFM compressor with a 9% duty cycle, paired to a manifold that supports dual-path left/right control. The EZ Mount bracket arrives fully assembled, compressing the install time versus earlier versions that required separate manifold and pump mounting.

The handheld LCD remote stores up to three user-defined pressure presets, and the companion iOS/Android app mirrors those presets while adding real-time system pressure readouts. Owners of F-250 and Ram 2500 trucks running Air Lift bags report that the ability to bump pressure up 10 PSI from the cab while merging onto a highway with a heavy trailer completely changes the safety margin.

The compressor intake draws from the engine bay, which exposes the filter to dust and moisture; several long-term owners have rerouted the intake into the cab or behind a grille vent. The install is moderate difficulty—plan on four to five hours if you are routing wiring and air lines cleanly.

This bundle mates the proven LoadLifter 5000 air springs for 2014-2026 Ram 2500 with Air Lift’s WirelessOne 2nd generation compressor, creating a single-package solution that eliminates the need to piece together components. The single-path manifold inflates both bags equally, which is ideal for fifth-wheel and travel trailer towing where the load is evenly distributed left to right.

The WirelessOne compressor operates at 120 PSI and pairs with both a handheld remote and the mobile app. The system retains up to three pressure presets, letting you switch between empty, loaded, and fully loaded with one button press. Owners report that the combined kit installs in roughly six hours, with the air spring side being the most time-consuming portion.

Several users experienced leaking T-fitting connections on the manifold; replacing the tubing and fittings with aftermarket push-to-connect components resolved the issue. The bundle does not include a decal for a clean dashboard install beyond the provided TrendsAuto sticker.

maXpeedingrods’ system is built around a dual-path manifold that lets you inflate and deflate each air spring independently, which is critical for correcting lean caused by uneven loads or off-camber parking. The 12V compressor delivers 120 PSI max pressure and includes a thermal overload protector for extended run cycles. The package is universal, so you supply the air springs separately.

The wireless remote communicates reliably up to 50 feet, and the mobile app provides real-time voltage monitoring and leak alerts. Owners installing on 2025 Ram 2500 frames note that the compact compressor body mounts cleanly with the included U-bolts and takes about three hours to wire up including the relay and fuse.

The tubing fittings included in the kit are the weakest link—multiple reviews mention swapping them for aftermarket brass or stainless units to prevent slow leaks. The app connectivity can be inconsistent on Android devices, requiring a Bluetooth re-pair occasionally.

Vixen Air’s VXO4841B is a universal bundle that includes a 200 PSI compressor, a 4-gallon steel air tank with seven ports, and all the ancillary hardware (pressure switch, drain valve, fuse, relay) needed to build a complete air system. The 1.8 CFM compressor fills the 4-gallon reservoir quickly, and the seven-port tank provides enough outlets for suspension bags, train horns, and tire inflation simultaneously.

The compressor is permanently lubricated and sealed against moisture, making it suitable for under-vehicle mounting on trucks, SUVs, and even boat trailers. The powder-coated tank resists corrosion, and the remote filter relocation kit lets you pull clean air from inside the cab or a fender well. Users installing on classic trucks like a 1959 Grumman report that the universal fit means you need to source your own air bag mounting brackets, but the compressor/tank package is complete and ready to wire.

The noise level is rated at 74 decibels, so it is not silent, but it is quieter than many comparable 200 PSI units. The one-year warranty is shorter than premium competitors, though the seller’s customer support has a track record of quickly replacing defective units.

Rough Country’s entry-level air spring kit for the Ram 2500 uses double-convoluted bags rated to 5,000 pounds and includes powder-coated steel brackets that bolt directly to the frame. The kit ships with DOT-approved air lines, inflation valves, and block shims to fine-tune the bag alignment on trucks with aftermarket lift blocks.

The standout feature here is the limited lifetime warranty—Rough Country backs the bags and brackets for as long as you own the vehicle, which is rare at this price point. Owners towing 12,000-pound goosenecks report that the bags virtually eliminate trailer sway at highway speeds and keep the headlight beam on the road. The internal bump stop in each bag protects the axle from hard contact if air pressure drops suddenly.

The air line fittings are a common complaint; the included 90-degree elbows are difficult to tighten in the tight confines above the axle, and the Teflon tape provided is low-quality. Several users recommend purchasing a separate T-fitting and standard straight fittings before starting the install to avoid chasing leaks.

TRQ’s PAA34392 is a complete air suspension replacement system for the Mercedes-Benz GL350, GL450, GL550, and GL63 AMG from 2013-2016. It includes two front air struts, two rear air springs, two rear shock absorbers, the air suspension compressor, and the valve block—everything needed to replace a failed factory air ride system in one shipment.

The components are built as direct OE replacements, matching the original equipment dimensions and connector types. The front struts are pre-assembled, eliminating the need to compress springs or swap top mounts. Owners of 2014 GL350 diesel models report that the kit restores the factory ride height and eliminates the “vehicle too low” warning light that plagues aging OEM air struts.

A minority of users experienced compressor failure within the first month, accompanied by excessive noise from the pump. TRQ provides DIY video support for installation, but the 8-piece scope means the labor is significant—plan on a full weekend if you are doing the job yourself with basic tools.
