I have an '07 4-door wrangler and had 35" tires and a 3.5" RC lift installed last April. Everything was great until this past month when I noticed the lift had lowered, with the passenger side being a tad lower than the drivers side. I had my Jeep looked at today and the mechanic said the lift kit was fine, that the coil springs had gone down from the weight. So I called RC today and the gentleman had me measure all 4 points from the middle of my tire to the bottom of the fender. He came back with "the passenger side is the correct height, that the driver side springs were wrong." He is going to ship me Two new springs for the drivers side to match the passenger side. Well, that's not what I wanted to hear, if anything the passenger side springs would be off because the driver side sits higher. I really enjoyed the look of the 3.5" lift when it was first put on, not knowing it would "settle" and I would lose about an inch.
If someone with this exact setup could measure different points on their jeep so I could compare would be greatly appreciated.
