I have a 1992 yj with the 2.5 4 banger in it. Has the manual 5 speed. Ive got 31s on it and wanting to change gearing to half way between 2h and 4lo when its in 2h or maybe a little closer than half way to where 4lo is now. I dont road it a lot so top speed isnt a problem. I never use 5th anyways now. I also want to upgrade to lockers. Whats the stock ratio on diffs? 4:10s? Ive seen several different answers on this page. Also whats the best option for me for lockers/gear kit? Ive installed a lot of yukon gears for customers in pickups/tahoes/etc and have had really good luck with them but never lockers so looking for opions on lockers/brands.
