    High Elevation Gear Ratio - 33's - 6-Speed (NSG370)

    Okay, I know there are a million posts about gearing (and I think I've read them all) but here is another! I could really use some last minute advice before I get my Jeep regeared. I am currently running 33" takeoffs, and may go up to 34" tires (285/75/17) in the future when the current tires...

    4.56 gears making noise

    2004 X with Dana 30&35, fresh NV3550 and fresh transfer case. In December 2020 I had my crappy 3.07 gears swapped out for Motive 4.56 gears and TrueTrac locker in rear. In late February I had to drive back and forth to work in snow (4HI at about 40mph). The following week I got a front...

    Gear Carrier Woes!

    So I'm needing some 4.56's in my forever build on my tj. I believe the cut off for my particular Dana 44 and Dana 30 is 3.92. I'm currently running 3.73. I know I need a new carrier, but I was wondering if anyone has any experience with the "thicker" ring and pinion sets that remove the need to...
