Anyone aware of an underdrive unit available for a 1996 Bronco 302 E4OD that works in two and four wheel drive (of course) that has dual ranges? One like 20% reduction and second maybe 100%? I found the Klune V, but it's main one is too low (400%!). I have 3.55's and would like to get the 20% so that it would be the equivalent near a 4.10 (20% actually being 4.26) for when I am towing a trailer. Then the second range would be for rock crawling along with low-range, especially on steep slippery descents. Also, if I look at my transfer case, how do I know if it is the Borg Warner or the NP200? (Both are 2.69 low range.) What model of Borg Warner would it be, if it is one? 1465?

Hmmm, I'm not sure if the website I got NP200 from is correct on the model number. Still, I would like to know which transfercase I have for sure.
