Bolt-On Air Spring Kit; Engineered by Air Lift is Key Feature
This is an Initial Review. A true assessment of long-term durability, air bag reliability, and overall performance under heavy towing or hauling loads requires this kit to be installed and used for thousands of miles under varying conditions. I have inspected all components, compared them to the original design, and installed the kit on a compatible truck. I will update this review after several months of use, including towing heavy loads, to report on its real-world performance.This is a complete bolt-on air spring (air bag) helper kit designed for specific late-model GM 1500 trucks (Trail Boss, ZR2, AT4, AT4X). The kit includes two air bags, all necessary mounting brackets, hardware, and detailed instructions. The key specification is that it is “Engineered By Air Lift,” a leading brand in the industry.Key Features & Initial Performance:Direct Bolt-On Design & Brand Association: The primary feature is that it is a complete, no-drill kit engineered by Air Lift. This association suggests adherence to established design and quality standards. The installation follows Air Lift’s proven method, fitting within the rear coil springs.Load Support & Adjustability: The air bags are designed to support up to 5,000 lbs (combined) and are adjustable from 5-100 PSI, allowing for fine-tuning ride height and stiffness when towing or carrying payloads.Initial Installation & Fit: The kit is designed specifically for trucks with factory-installed lifted suspensions. All components fit as intended, and the air lines route cleanly to a provided schrader valve for manual inflation.Special Note: This is an auxiliary helper spring system, not a full air suspension replacement. Its purpose is to supplement the factory springs to maintain level ride height under load, not to lower the vehicle or provide primary suspension support.Initial Verdict: This appears to be a well-engineered, brand-backed helper spring kit that installs cleanly on its intended applications. The “Engineered by Air Lift” detail is a significant point of confidence. I will update this review after extensive towing and hauling use to report on: air bag durability, seal integrity, bracket strength, and overall effectiveness in controlling sag and improving stability.

Easy air springs install
I buy ATVs and haul them with a trailer, so I decided to get, new air springs suspension kit. I want to tow my ATVs, without my truck’s rear end sagging. The kit made by Atlus Products Company, based in Michigan, included the springs, brackets, mounting hardware and instructions. You definitely need to read the instructions, in order to follow each step, correctly. Also, make sure that you have the correct tools when you begin, including a socket set, torque wrench, drill, line cutter and of course, safety glasses. I’m happy that I bought these springs, but it took several hours, for installation, since I’m not a mechanic. I didn’t run into any problems, because I took my time and made sure, I did each step, properly. Thank goodness, they fit well, too.After installing, I tested out how the truck drove and it was much better, than before and I will be able to tow the ATVs, with ease. The quality, is really good and the price was right, on this suspension kit, which was great.

Heavy Loads Without Truck Drama
This setup makes a noticeable difference the second you load weight into the bed. The rear stays level instead of doing that saggy squat trucks love to do when you’re hauling or towing. It doesn’t turn the ride stiff either, which was my biggest concern. Everything still feels controlled, just more confident.What stood out most is how predictable it feels over uneven roads. Speed bumps, highway dips, and uneven pavement don’t cause that bouncy rebound you usually get when the rear end is stressed. The truck stays planted instead of wobbling like it’s unsure of itself.Install-wise, this is clearly made for people who don’t want a science project in their driveway. The pieces line up clean, the hardware makes sense, and nothing feels flimsy. Once it’s dialed in, you mostly forget it’s there — which is exactly the goal.

made a huge difference!
I installed this air bag suspension kit on my Silverado Trail Boss and it has made a noticeable difference when hauling and towing. The truck stays level under load and feels more stable, especially over bumps and uneven roads. The kit feels well built and everything lined up the way it should during install. Ride quality is still comfortable when unloaded, which was something I was worried about. It is not the cheapest option out there, but it does what it is supposed to do and feels like a dependable long term upgrade.
