New lease on the trucks life
We put this kit on one of our F-150s out at the ranch after years of dealing with rear sag every time we loaded up hay bales or pulled the flatbed trailer.Installation was straight forward since its a bolt-on job no drilling needed we had it done in an afternoon with basic tools.The difference is clear now when hauling heavy the truck stays level and the ride feels more stable without that bottoming out feeling we used to get.It’s adjustable from low pressure for daily driving to higher when towing and it handles the load without drama. The build quality seems solid with no leaks after a few months of use. It’s working great.It’s made working around the ranch a lot easier on this truck. Well worth every cent.

Finally! A level ride while in tow. Should have done it years ago
Final outcome was exactly what I needed and was hoping for on my 2021 F-150 Lariat 2.7L…. A level ride under tow! Finally drives so much better with that load on there now. Install was fairly easy. I never did anything like this before with shocks/ suspension kinda stuff so my install time is a bit embarrassing and make sure you have all the tools needed before you start. But I could do the install in half the time if I were to do a second set I bet. The quality of the kit is of very good quality. Built to last and up for long hauls with no issues. Everything seems heavy duty. Didn’t notice a single design flaw or issue in any of the pieces at all. Everything fit as described and expected. Definitely makes the truck look more natural with the trailer in there and not rose up in front. And the ride is smoother for sure and makes the driving so much easier too. Less to worry about and less stress on points that should not have the extra weight there. Value for the money is right on point with this kit. If you pull weight regularly or going on a longer road trip, get this kit and throw it on there. It’s needed and makes such a big difference

Leveling Out the Heavy Hauls
This air bag suspension kit feels like the kind of upgrade truck owners appreciate right away. The parts look solid out of the box — the brackets, the hardware, the bags themselves — everything has that heavy-duty feel without unnecessary bulk. For anyone towing, hauling tools, or loading the bed with equipment, this setup adds stability that you can feel even before you hit the highway.Installation is straightforward. No mystery drilling, no funky modifications, just bolt-on with clear instructions. Once everything is locked in, the kit gives you a wide pressure range to dial in exactly how firm or soft you want the rear end to feel. It’s the type of adjustability that pays off when your loads aren’t consistent day to day.The biggest difference comes when you’re pulling weight. Rear sag gets reduced noticeably, steering feels more predictable, and bumps hit softer instead of bottoming out. I tried it while hauling restaurant supplies and a trailer, and the truck stayed level instead of dipping and dragging like before. Night and day difference.These bags also help with everyday comfort. Even when the bed is empty, dialing the PSI lower gives a smoother ride, especially on uneven roads. Drivers who alternate between commuting and hauling will appreciate that flexibility.

Great air lift suspension kit for leveling, easy to install, great quality.
Great kit for supporting heavy loads and dealing with rake on an F150. Very easy to install yourself, instructions are clear and precise. Build quality and fit are excellent, no leaks and very sturdy heavy duty materials. Works well for leveling the load and improving handling and comfortability. Great price for what you get, a great addition you can make if you tow or haul a lot, great price for what you get.
Customer Review –
Good quality parts, exactly as described.
The kit’s build quality was clearly evident – all metal parts came with no burrs or bad welds, and the hardware looked sturdy. The brackets and air bags all lined up with existing holes on the F-150 frame, eliminating the need to add new holes. The included fittings all held air after tightening; therefore, there were no leaks after installation. Overall, the fit and finish reflected the kit’s price and facilitated a simple installation. Functions great for the price
