Hey Fred, my 'puter isn't working right with this forum so I couldn't quote the bits I wanted to, but please explain a bit more about the doubler. Is that similar to a Klune doubler? Or is it a re-make of what's in the NP231/ or d300 (couldn't figure out which or if it's part of both) to add a doubler. For me 1:1 is great for sand, 2.72(stock NP231) is great for most trails, but I'd really like 4:1 or lower for some of the crawling if I could do it w/ only 1" taken from the drive shaft length. I can't handle much more angle in the drive line w/ out rebuilding it again to accommodate.
Thanks,
- C
