Maybe it is a 9LL, never knew one existed, I shift just like the 8LL we have. Its gotta some extra low low i believe. The 4.88's are awesome though, we can do 70 mph and then go off road onsite and have no problem. I don't know how these guys use 4.30's and even ratios in the high 3's for dump trucks....I wish we had gotten more lights, like the mirror turn signals, etc. I was just happy to get the SS accesories we got lol. The windshield could be split curve or one piece, or the traditional spilt flat, there all options.
