Air Lift Company now offers a kit that allows elite users to upgrade the components of their existing Load Lifter 5000 series air spring kits to those of the new Load Lifter 5000 Ultimate Plus kits. With this upgrade opportunity, users can now have the longest-lasting load support system that money can buy, without needing to purchase an entirely new system. For those with existing Air Lift Load Lifter 5000 series kits on their vehicles, the power of air is undeniable - up to 5,000 lbs. of load-leveling capacity, eliminating squat, poor headlight aim, trailer sway, and body-roll, creating a comfortable ride and stress-free towing experience. Now, Air Lift offers elite towers and haulers the opportunity to upgrade the components of their existing Load Lifter 5000 series systems to those of the new Load Lifter 5000 Ultimate Plus. With this upgrade kit, Air Lift users can add stainless steel roll plates, mounting hardware, 10 feet of braided air line, and military-grade AN fittings to their system for added protection from heat and road debris, as well as leak-free connections. All of the existing benefits of the Load Lifter 5000 series system are preserved, with the addition of a new level of the safety and comfort that Air Lift is known to provide. As the leader in air suspension products for more than 65 years, Air Lift is committed to delivering quality load support parts that last. To ensure the highest quality, longevity, and customer satisfaction, the key suspension components, including the air springs and all hardware, have all been torture-tested on our hydraulic test rig. With a limited-lifetime warranty - not to mention the Air Lift reputation for great customer service and technical support, should you run into any snags in the installation process - you can purchase this kit with peace of mind.

I have had airbags on other vehicles. I always used the stock tubing but this time I thought I should upgrade to the fancy steel braided line because it looked more robust. come to find many people complain about leaks at the fittings on this package. I wish I had not spent the time and $$ on this. The instructions are vague, they give you way too many parts and say figure it out based on which air lift model you have. this makes installation a pain in the butt that takes way longer than it should.i've identifed and tightened all the fittings where leaks could be found with the soap water spray approach. it's still losing about 5 lbs a day on both sides. not acceptable. people have stated that the swivel fittings on the air bags are the culprit and there is no way to stop a leak there.save your $$ and just use the tubing and fittings that come with the air bag you bought.

Bought an Air lift kit years ago and never got around to installing it. Decided to tackle this long awaited project and found I was missing a roll plate. The ss roll plates and the ss braided air lines were exactly what I needed. For me it worked well and the pre-assembled air lines were just the right length for 2001 Ford f350 crew cab short bed.

Not real sure it was worth the extra money Nice to have AN fitting and braided lines It doesn’t include the bolts in stainless for attacking top mount The bolts rusted right away Lots of extra SS hardware you don’t need included
