"I have the JKS ACOS system. I'll explain why. I have the RE 4 1/2 longarm lift. According to RE will allow for 37" tires which I have. I like the bigger tires. It's what I want. However, adding the additional weight of steel bumpers, a winch, tire carrier and a 37" spare brought the ride height down to better suite a 35" tire not a 37". Add to that the additional weight of tools, recovery equipment, cooler full of food, beer, etc... and additional passengers, as I have a four door, I am pretty much back to stock height, with 37" tires of course. My tires are constantly stuffed in the fenders while on trails. One guy even asked me if my lift was stock. I called RE and they would not offer a solution that would alter their system. I felt that I had to do something because I wasn't happy with my setup. So I talked to a guy about putting 2" coil spacers on. He suggested the JKS ACOS system pointing out that I would not be committed to a specific ride height. If youre not happy after putting on a fixed height spacer then what do you do? I knew there was a significant price increase. We all know how much. Still I bought into the idea of customizing the ride height to suit my needs. They can be adjusted front and back, left and right. Level it out, rake it forward, whatever. The front spacers are adjustable 1" to 2-1/2" and the rears are 2" to 4". Kind of like an insurance policy. They never seem like a good idea until you need it.

So here's my thinking and I could be wrong. Aftermarket lifts while well thought out and engineered still have limitations relative to the vehicle and it's intended use. That's why we are always finding ways to tweak things to better suit our style of driving. And vendors provide us with new products in their never ending endeavour to improve our rigs. Is the JKS ACOS system worth the price over fixed height coil spacers? In my case yes. I think it is subjective to a persons wants and needs. Oh, I forgot to mention. They look cool too. "
