Review on 🚗 Enhance Your Vehicle's Performance with the AIR LIFT 60742 1000 Series Rear Air Spring Kit by Mark Adlesh

I bought these for my 2001 QX4 to stiffen the rear of some of them and also as an off road aid to provide enough ground clearance. They really help on both counts, so I was very happy with the functional perspective. However, durability is questionable. I installed it in April 2010 and in September of that year the left one stopped holding air due to a bag rupture. The replacement was quick enough, but since they are in the coils, fitting them is a serious job. Fast forward three years and the other side will fail again - crack and lose its breath. The replacement took longer - I'm still trying to contact someone but it's partly my fault as they left a phone number a while ago and I lost it. Assuming the company sends a replacement, I still have a few hours of work to remove and replace the second failed airbag. I carefully monitored the air pressure on a weekly basis and typically kept only 6psi on each side while banging on it. up to 10-12psi when driving off-road or driving with a heavy load. I had to spend a full day on the initial installation, half a day to replace one and another half day to replace the second defective pouch. Overall I am disappointed with this product. Great concept, questionable durability.
