I thought that I had understood the nomenclature of the RockTrac t-cases, after reading a thread on the internet somewhere a while ago. I understand some of the history behind New Process (NP) New Venture (NV), New Venture Gear, but what I do not understand is the "J" designation on the t-case badge.
My understanding was the J's were 2.72:1 ratio and the "OR" is 4:1. My 05 TJR has a 4:1 t-case, which is also stated on the build sheet - yet, the badge says "241J". I read long ago that OR stood for Off-Road, and the 4:1 t-cases have "OR" and not "J".
See where I'm confused?
