Air Lift 57541 LoadLifter 7500 XL Ultimate Air Spring Kit

top notch

These things are beefy. If you have a 1-ton pickup with a heavy load, these will easily level your truck and help smooth out your ride. With the truck unloaded, I did not notice any difference in ride with the minimum 5lbs of air. After hitching a 5th wheel with 3K pin weight I would get 2 inches of squat until the truck came in contact with the upper overload springs. Airing up to 55lbs helped level the truck and smooth out the ride. Installation was straight forward following the included instruction manual. I had also watched some videos as well. I did come across a neat trick where you cut about a 4-6 inch length of air tube for each spring and insert it into the fitting. Then you compress each spring, and when compressed plug the open end of the air hose (I used golf tees.) This keeps the spring compressed and make it easier to maneuver into position. Once in position, remove the short piece of air hose and the spring return to their resting position/size, and ready for the rest of the install. Really the hardest part of the install was trying to determine how I was going to run my air lines. I did get the WirelessOne compressor with easy mount, but I did run one line to the rear license plate for my manual inflate/deflate option if needed.

They have met all my expectations. They were installed by a professional, and now I can go ahead and haul my fifth wheel and that I’ll be level or anytime I use it for other things with a gooseneck or even a trailer.

quality is very good, install to my GMC 3500 and just fit perfectly,
