Welcome to the forum cakes567!!!!

Your questions is a tricky one, currently, but with some detail, I'm sure we can help ya. What year YJ do you own, and what engine do you have in the JEEP (these are always helpful anytime you need information). It's helpful because it makes it easier to determine what other components may/may not be on the JEEP (under normal circumstances/from factory). Do you know which rear/front end you have. Some are stronger than others.

Your gears are about the same strength across the board from 3.07-4.10. The weak point is the d35 axle shafts. With the set up you have that thing has to be a dog, meaning no acceleration power. Swap the gears to 4.10 or 4.56 and the jeep will become a lot more responsive to throttle.
