  • Gears

    I have a 87 yj with a 4" lift and 33" tires and i am running stock 3.07 gears. what should i go to???

    I think that my preference would be a set of 4.11s. It'll give you preety good crawl speed and with overdrive you should keep up with highway speeds easily.

        First of all I would not put any money into a Dana 35. I'd look for a Ford 8.8 with 4:10 gears and find a Dana 30 from a Yj with 4:10 gears.
        other things you can do a old Ford Bronco 9" (66-77) or a Scout Dana44 rear end both the 9" and Dana 44 will have a CJ bolt pattern so use wheel spaces to go from the CJ 5on 5 1/2
        to a Yj 5 on 4 1/2.

          The 4.10's I have in my 94 with a manual tranny won't pull the 33 inch tires in 5th gear, going to 4.88's. I'm also upgrading the rear axle to a dana 44 because I'm a huge fan of the skinny pedal and don't want the lower gears to snap axles in the dana 35...

            I went straight to 4.88s (biggest thing you can stuff in a 35) and I still have issues on 33s. Albeit its a 2.5L on a stick.

              Dont know if you are still running the 307's. I haven't been on the site for a long period of time. My experience with my 94 with 33s 5 speed (now) and 2.5, I went with 488's. Great off roading down hills with no brake pedal. and most times tappin skinny pedal to keep it running.Unless you have the other diffs available(read cheap) I would build what you have and take care of it too.

                IMO if you have 3.07 stock you have a 6cyl so in that case, I would say 4.56.

                  I have 4.56 in my 91YJ with the 6 cyl 5 speed and it works great. It crawls nicely with 33 or 35 inch tires and will run 65 down the road easily.
