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?
