So, I don't know for sure if Amanda actually makes the IFS/IRS Jeep JK Wrangler they had on display at the 2015 SEMA Show but I do have to say that I was very impressed with the potential of what I saw on it. Talking to the guy responsible for the design of it, I found that it actually has a floating differential up front of which is tied to the driver side a-arm and this allows it to have an impressive 16" of travel up front and 14" in the rear. As you see it in these pics, it was running 38" tires and they still needed to do some trimming to clear them at a full stuff. I'm sure it would have been a leap for Jeep to do something as innovative as this but I for one would have been all over it.
