I run a northwest fabworks crawl box in my scrambler. It allows me to use the regular gears/t-case hi-low, or put the crawl box in low and the other stuff in whatever. Gives me a wider range of gearing options for different situations. Sometimes low/low is too low. If you do the transfer case reduction swap you may find hi is too high and the new low is too low. I like options.Phils67 wrote:....go on...?tedlovesjeeps71 wrote:Crawl box...
Probably not. There is very little these days that isn't focused around the Jeep Dana300/NP2xx bolt pattern. Parts like that for the older transfer cases are getting harder to come by. You can still rebuild them easily enough but significant modifications like a crawl box just aren't out there.Phils67 wrote:Thats pretty cool but would it work with a Dana 20 that has a "texas" bolt pattern?
I'm only at about 180:1 but I don't have as much motor as you do.jeepininawk wrote:My crawl ratio will be around 48:1 or so, I forget. It'll be a nv4500 with a divorce 205 case and 3.55 or maybe but doubtful a 3.73 ring gear. Rolling on 35's and powered by a VORTEC 454.

The only real place that power matters is in high range. 35's with 3.55's for instance is not going to be great when climbing grades and puts a lot of stress on u-joints. The 454 should have enough grunt for it, but it won't be ideal.
