Transfer case swaps?

Are there any advantages that a Dana 300 has over the NP231? Is one shorter than the other?

Considering a SOA conversion next spring, and I figure I'll have to swap the case too.

Main difference is how it it's built. The 300 is cast iron and all gear. The 231 is alum and chain drive. I think you can run a twin stick in 300 too and cannot in a 231.

The 300 is shorter in stock form and probably even with the trail housing eliminator, it is still shorter. It is passenger drop where
as the 231 is drivers drop. The distance from the center of input to the center of the front output is less, so clearance can be
tight with the 300 which may be an issue depending on what transmission you have. This just means that sometimes you need
to clock the 300 down to get clearance.

Re: Transfer case swaps?

The 300, besides being a gear driven cast case, is a better canadate for a 4 to 1 conversion. The planatary gears of the 231 have given strength problems to the 4 to 1 swaps. If your thinking about doing it on your YJ, I just did it to my '93 with great success. I put the 300 and an NV4500 in and still ended up 2 inches shorter than the ax15 and 231 with a short shaft kit. Its a little noisey, a lot less refined, but brutally strong in a SWB jeep. I used an early (75) wagoneer 44 for the frt to get right hand drive along with ford and chevy parts to get 5 on 5.5. A scout II rear and I was ready to go. By the same token, if you don't need that excess, the 231 seems to do well with resonable size tires and a little care from the driver in the accelerator dept. Best of Luck!
