my plan is to install this one in the rear and a Dana 30 27 Spline 3.73 Up Front TrueTrac in front, in my 98 xj, does it fit? which gear set ratio should use with 33" tires?

Asked by Meyko from SC, Brasil on

Hello Meyko, With a 33" tire we normally suggest a 4.56 gear ratio if the vehicle is driven mainly on the highways. if the vehicle is mainly off-road we suggest a 4.88 gear ratio. I hope that helps answer your question. Thank you.
