Good, sounds like I can do lift first without axle gear ratio up

It sounds like keep the stock axle gear ratio does not
hurt too much. Besides, mine is 3.73, so maybe more forgiving on trail than yours.

Therefore, I think I can just confidently order a lift
kit first.

With your recommendation, I decided to use a Teraflex
4 inch kit that has full flex arm (8 arms) and shocks.

Also, since the lift is more than 3 inches, I also going to order front and rear teraflex drive shaft
to alleviate the problem

How do you think about this plan?
