Built for the Load: Meet the LoadLifter 7500 XL Ultimate for 3500 HD Chassis Cab

When your truck is your livelihood, there’s no room for compromise. Whether you’re hauling heavy materials to a job site, towing equipment across rugged terrain, or managing a demanding commercial fleet, you need suspension support that works just as hard as you do. That’s why Air Lift Company is proud to introduce the LoadLifter 7500 XL Ultimate (PN: 57543) for the 2016–2025 Chevy Silverado and GMC Sierra 3500 HD Commercial Chassis Cab (2WD/4WD). 

This kit is purpose-built for serious hauling—and it's here to take the pressure off your suspension, your cargo, and your bottom line.

Why It Matters for Hardworking Trucks 

From contractors and landscapers to ranchers and fleet managers, the 3500 HD Chassis Cab is the workhorse of choice for heavy-duty applications. But even the most rugged truck has its limits when it comes to load stability, squat, and ride comfort. That’s where the LoadLifter 7500 XL Ultimate comes in.

Top Features That Work for You 

• Massive Load-Leveling Power  With up to 7,500 lbs. of load-leveling capacity, this kit is built to handle the biggest jobs without breaking a sweat. It’s the muscle you need when your truck’s doing the heavy lifting. 
• Extra Air Volume = Extra Control  Featuring a 7-inch double-convoluted-bellow air spring, the XL series delivers 20% more volume than our LoadLifter 5000, giving you better ride quality, improved handling, and more precise load leveling. 
• Internal Jounce Bumper = Built-in Peace of Mind  Even with zero air pressure, the integrated internal jounce bumper helps protect your suspension and cargo from harsh bottoming out—great for unpredictable roads and surprise dips. 
• Adjustable for Any Load  Air adjustable from 5 to 100 PSI, this system adapts to your exact needs—light loads, heavy trailers, or anything in between. 
• Engineered for Long-Term Durability  Upper and lower roll plates shield the air springs from abrasion, while a rugged side-mount design ensures a stable, secure fit. 
• Ready for Total Integration  Fully compatible with Air Lift’s on-board compressor systems, including WirelessAir and WirelessOne, for easy inflation on the fly—right from your smartphone. 

Installation Made Straightforward 

The LoadLifter 7500 XL Ultimate kit (PN: 57543) installs with standard hand tools and a medium drill. It requires four holes to be drilled on each side of the frame—a straightforward process for most professional installers. Once it's in, it’s set to perform for the long haul.

Who’s It For? 

• Contractors who need consistent ride height, safety, and control even under shifting loads. 
• Fleet operators managing uptime, cargo protection, and driver satisfaction. 
• Ranchers and landowners towing equipment over dirt, gravel, and unpredictable terrain.
