Review on Enhance Performance with LIFT 60786 1000 Air Spring: A Must-have Upgrade for Ultimate Suspension by Steve Washington

I installed them very carefully following the instructions on my Sequoia Gen 2. I am a very experienced mechanic and BSME mechanical engineer. Worked fine for a few days then died. I tested them for leaks with soapy water and found none, but they were lazy. By the way, it's not very easy or effective to fix bugs after they've all been put in the quill. No wonder the ride seemed so smooth. They weren't puffed up! Installing them was a waste of time. Now I have to remove them. Not a very fun activity. Ironically, my technician at the Toyota dealership stopped me from installing them. I should have listened to him. Maybe you have better experiences than me.
