I don't understand why everything has to be a "$2500 Atlas" or a "$2500 rear axle" when building a rig, most people don't have $15-$20K just laying around to drop on rig as a hobby especially in this economy. Just to clarify I'm not advocating that the 231/D300 is the end-all-be-all transfer case upgrade, I'm just saying that there are OTHER options out there outside of buying the most expensive thing on the market for a particular part that might be better suited for a particular wheeler, their wheeling style, terrian type and their budget. That being said, why would Advanced Adapters makers of the Atlas T-case actually manufacture and sell multiple doubler kits on their site using a D300 if that was such "bubblegum and bailing wire" method of doing things? I still stand by saying that a 231/D300 doubler literally has MORE selection than a 2-speed 4.3:1 Atlas and can be built REALLY STRONG for LESS than going with the Atlas t-case option. Just looking at JB Conversions site you can get a D300 rebuild kit for $125, a 32-spline D300 front output for $175, a 32-spline D300 rear output for $390, $200-300 for a used D300 (that's if you don't shop around and just buy one from a yard), FREE 231 from the project rig and $500 for the 231 doubler kit totals $1390. I'm not sure what the going rate is for a D300 rebuild but I doubt that it would run $1k which is the difference between the 231/D300 build and the 2-speed Atlas price. Furthermore there are many detailed D300 rebuild write-ups on many reputable sites out there so the average wheeler should be able to rebuild one with basic tools if they so wished. Plus most people involved in this sport/hobby actually enjoy working and learning about their rigs, I know I do <img src="/forums/images/graemlins/smile.gif" alt="" /> . It brings a sense of accomplishment knowing that they built/worked on something themselves and actually know how it works as opposed to just having someone else build and install something for them and then if they ever need to work on their rig on the trail when something goes south they have no idea where to even begin working on their rig. So to reiterate, there is more than one option out there when building ones rig... <img src="/forums/images/graemlins/cheers.gif" alt="" />
