I have been trying to do my homework and search the forums, but I'm still a little confused, so I thought I'd ask for some guidance. I plan on getting a good chunk of change soon (about $3,000 if things go right), and I want to strengthen my drivetrain. Buuuuut I don't know where to start, other than getting a new front driveshaft. ~$500...so what else should be done to beef it up? I've heard regearring and new c gussets (no idea what that even is) is a must to go with 37s or above (which i plan on doing) What should I regear to and how much would it cost? How do I know what type gears to get? What gears do I have? Or should i try to get completely new axels? Sorry for all the questions, but I'm completely lost here. Thanks so much...it's really appreciated.

I've got a 2011 2 door sport with the Dana 30 front and Dana 44 rear. I thought long and hard about ordering a prorock 44 but $5000 was a lot of money for me to come up with considering I'm only 21 years old. I decided to beef up my d30 I ordered c gussets sleeves lca skids chromoly shafts 5.13s and a Aussie locker for my front d30. I also ordered chromoly shafts 5.13s and a Detroit locker for the rear d44. I'm still debating weather to go 35s or 37s but I'm leaning hard towards the 37s. I don't consider myself a hard core wheeler and down here in Mississippi my jeep will mostly see just mud and clay and I think the d30 will be fine as long as I don't get stupid. On the other hand my jeep is not my dd so if I break the d30 I can afford to be down. And that just gives me an excuse to build it bigger and stronger
