I'm currently running 4.10s in my xj with hpd30r and 8.25 on 33's I want to go with more gear. Don't know if I'm going to increase tire size, more just want to lessen the effort required to turn the wheels. I've heard 4.88s can break, but being I don't plan to ever go larger than a 35 tire, will I have that issue. or should I stick with a 4.56? thoughts?

If you are going to be driving it on a daily basis go with 4.56 or leave it at 4.10 for better gas mileage. If you don't care about that sort of thing or it's a straight up trail rig go all out on 4.88's and enjoy the torque until you snap a shaft in your stock axles.

456 gears are a little stronger then 488, because it turns using two teeth, 488 using just one, if you want torque get a 4:1 t-case
