Review on 🚗 Enhanced Air Suspension Kit - Air Lift 1000 (Model 60815) by Montrell Copeland

**UPDATE** Two years later and still reliable. I figured there must have been a leak at some point, but found that the schrader valve had tripped and was letting air through. I pressed it about a year ago and I've only upped the pressure a few times since then. Before I found a loose valve, I filled it weekly. **END OF UPDATE** First test December 2016: I just installed them and drove 2000 miles on a full charge. Half of it is on the Uhaul 4x8 trailer. I am very impressed with the driving stability they offer. The difference in fender clearance (with 35 psi bags) between an empty van and a fully loaded van was about an inch. The wheels aren't hidden under the fender, but are angled like many vans we've seen on our trip. I set them to 35psi when we left and tested them before returning after about 6 days and 1100 miles and they were 30psi. I love the extra rigidity in the rear that they provide even when unloaded. They make a little noise as the suspension flexes at low speeds as the springs rub against the brake pads. It's not intrusive and you only hear it at slow speeds. Also have a set of rear lower spring pads handy. There were 128,000 in our van and one was shot outright. The other was very worn out so I replaced both of them. They cost about $10 each at the dealer. Then why did I only give 4 stars? The instructions omit important steps and tips. For example, they don't say anything about deburring holes you drill in control arms. If you don't, the sharp edges of the drilling will cut your pockets. They don't mention cleaning where the pockets touch, which is important for durability. They don't mention that the tubes are lined to minimize abrasion and they only included a small piece of tube protection. Also, I don't have the strongest hands in the world, but the supplied hose would NOT slip and sit on pocket fittings or a tee. What they don't mention is that if you gently heat the plastic tubing with a hair dryer or similar and quickly reassemble it, it will slide back together. The hose slides MUCH easier onto the fittings and shrinks as it cools. Have a pry bar handy when attempting to reinsert the control lever screw into the steering knuckle. It takes a little persuasion to get back in line. If you place the inflation valve low enough on the vehicle, you can use a bicycle pump to inflate/service it. They are small and inflate faster than a single mountain bike tire. In general, they can be difficult to install, but they work great. Time will tell about the durability.
