    I blew up my pinion bearing, which chewed up my ring gear. So now I'm looking for a Ring and Pinion set for a 14Bolt.
    I'm am currently running 4:11's on 40"boggers but would consider any gear sets from 4:11 to 5:13's because I'm about to buy some 44's
    I could use any suggestions and/or openions on which gear to run with 44" boggers too. I'm also running an SM465 to a NP205
    Let me know if you have any gears sets worth selling.

    Who said size doesn't matter?

    For 44's I'd go with the 5.13's.

    I'd like to have 5:13's, but I want to make sure that I get a good low gear while keeping a decent highway performance. I drive my truck anywhere from 5-150 miles to go play in the mud. Keep in mind that I do have the granny low with the NP205 which helps alot on the low range conversion.

    If you have a non-overdrive trans, you're looking at 2550 RPM at 65 mph with 44's and 5.13's. There's a calculator you can play with at <a target="_blank" href=http://www.4lo.com>www.4lo.com</a> if you want to test various combinations.
