tell us bit more about your setup,  originally the YJ had 4.10 axles (with 4cyl) and about 28inch tall tires,  auto or 5spd ..... added weight like winch and bumpers

Re-gearing makes a big difference on-road and off-road. A turbo would work as well, but still wouldn’t get you the mechanical advantage that the proper gears would.

As low as you can go. 4.88 would be a good place to start.
