So I have done some searching and Im sure that it has been asked before but I didn't see it.
So here I am with stock Rubi axles, 5.13, 37s, and DTD. I feel now that I can push my rig but im worried about my axles not holding up to what the DTD can dish out. My wife and I with our new son like to take the Jeep everywhere. So I want to be able to be comfortable on the road as I am offroad. Be able to wheel the rocks, bomb the fire roads, and be comfortably driving home. That being said, I know how the 3.8L (Low Output) is with 5.13 and 37s. I can use cruise at 65 but if I hit any kind of angle, I have to hit the OD button. I have 45,000 miles on the 3.8 and not looking to do a motor swap until it shits the bed. So here is what I was thinking...
PR44 front and PR60 SF rear and stick with 5.13 and 37s. (Cheaper route but solid for 37s)
PR60 front and PR80 FF rear with 5.38 and 40s. Way more expensive but the last axles you will have to buy.
For those that have ran both setups w/ the 3.8L (Eddie) how do the two compare as far as drivability? I know offroad the 60/80 combo and 40s is superior but I would like to be comfortable on the road too. (For the wife and kiddo of course). I have seen the charts for tires size and gears and what rpm you will have at 70mph. It says that the 5.38 and 40s is about 100rpm less than 5.13 and 37s. Is that a huge difference?
I know the price difference is way different for the axles and when you factor in wheels and tires too. But I can just save a few more months. I just want to do it once and be confident on the trails and be able to hop in the Jeep and drive 1000 miles comfortable.
Guys I appreciate you help and honesty.
