So as i'm building the bass boat up this winter for more abuse on the trails next year. I've been wondering if the stock dana 20 transfer case will handle all of the abuse for another year as the trail's get harder and my tire size goes up once again. As of now i'm runing BFG mudd terrains 35-12.50 r15 i'm steeping up to a super swamper tsl radial size 36-14.50 r15. The bass boat is'nt a power house by any stretch. just a 302 bored 0.30 and a rv cam. I have 4.10's in the diff's and a detorit in the rear. It has an np435 for a transmission. I got a spare dana20 from a buddy and wondering if i should do the cold duck kit which i believe bring's the gear ratio to 3.15 and while i have it apart throw in the 32 spline output shaft in the rear and up the yoke size too 1350 at least,and twin stick it. Or should i save the money and invest in an atlas 4.3 or the stack b box?
what do you guy's think and have the best experience with? thanks matt.
