So im thinking about making a huge jump, and get my jeep some new shoes. I have 33's and a 2.5 inch and i want to get some 37's. I plan to change my dana 30 to a ProRock 44 and regearing to 5.13 and flat fenders. I want to know if i can just get the housing and build it up slowly, and if theres anything else that i will need with making the jump to 37's. After this purchase i plan to get RK long arm system. Please help me to get all that i need really want 37's

 

I'm running 35s with flat fenders and a 2.5 inch lift ..no problems with stock gears but you gotta cut the pinch seam on the corner if your gonna wheel it or you'll shred the tires

 

im rocking 37s on my 30 right now. Surprisingly i've had no issues with it so far. I may down grade to 35's eventually, but i have a 2.5 inch lift/1.5 body lift and front tube fenders. But i've beat on mine pretty good so far and havent had any issues. I do plan on upgrading eventually tho

 

You could put your inner's from the D30,need up graded axle shafts.So just spend the funds up front and do it right the first time
