Alright guys in a bit interesting situation and I need some pointers. I know this is an age old question, but I have some specific questions for this thread. Anyway I came across this really amazing deal for a wheel and tire combo, I am talking more than half price and these things are basically new. I think the reason why this set is so cheap is because of the bolt pattern. Obviously it is 6x5.5, so no jeeps and this setup is made for a trail rig not a mudder. Where the problem begins however is that they are 38 inches. Yes I know not the greatest idea, but I really want to do it anyway because it is my dream setup and this opportunity is way too good to pass up. One of the questions that I have this is about the gear ratio. I have an Alpha, so 4.10 gears. I did a calculation to determine the new gear ratio I would need and it is 4.72. Here is my math to double check:
4.10 (Alpha Gear Ratio) X 38in (New Size) / 33in (Stock Adv Package Size) = 4.72
From what I know the stock axles can only go up to 4.56 correct? If I were to upgrade to this gear ratio to 4.56 would I be okay or will I have shifting problems and will it suck at crawling? (Assuming I update the PCM) If I were to do this am I just asking for trouble from literally everything under the truck like the driveline, steering, and axles? Do note that I have the rancho, outfitter tire rods, and mayhem metal works steering rack clamp so that may help a bit. I already looked it up and each tire is pretty heavy at around 100lbs without the wheel. My tires are about 55lbs each now. Another question, if you guys advise against this, should I get them to use it later when I do a SAS? Or at that point should I be looking at some beefier 8 bolt axles like 06H3?
If anyone can help it would be appreciated!
