Transfer Case Selection, Feedback?

Hey ladies and gents.

I am in the planning phase of a 4WD conversion for my sprinter. I have been looking at commonly used Jeep transfer cases which mate to a NAG1 (Jeep cherokee/ late wrangler).


For those with 4WD vans, what are your thoughts on low range ratios? 2.72:1 is pretty common (NV242/241). 4:1 is an option on the NV241OR (wrangler rubicon)

The factory 4x4 Tcase is 1.6:1.

I don't have a need to "rock crawl", and I would likely be using low range for steep climbs, and tracks. Nothing technical.

Our van weighs about 8,500lbs (plus 4x4 bits). So I think the 4:1 ratio would put way to much torque through factory bits?

The 241OR is for rockcrawling, I run one in my rockcrawler and love it...I would never consider it for a van. I'm building a 4x4 express van right now and using the NV263 (also 2.72) which is plenty of low end for anything I'll ever do.
