Install seemed complicated until I had the first side completed - 2nd side was a breeze. If I were to change one thing, there is a corner of the bracket that rubs on the plastic fuel tank a hair. I would grind that down a bit next time. (It didn't bug me enough to take the whole thing apart). I found that 30 psi levels my truck and 11k bumper-pull trailer perfectly. It stiffens the ride a little and keeps me from blinding oncoming traffic when towing at night. I control them with the Air Lift compressor via Bluetooth (app) or remote and it works amazingly.
