    I just got a Dana 60 and 70 for the k5 and I am trying to pick gears because I need to regear and ARB both of the axle's.

    I am thinking 5.13's and 37" Krawlers. What do you guys think? Too much gear or ok.

    Thanks a lot.

    id go 5;13's, cuz if you decide to go with a bigger tire you still got the gearing for it, plus you got the OD

    7;17's i would think the pinion would be gettin pretty small.

    6.17 gears with your current set up would net 2600 RPM's at 65MPH

    crawl would be 102:1, which is what I have in my doubler, but I am not sure what you want to use your rig for.

    Well I was thinking 5.86's and 40's but I don't really need that much tire yet.

    Also I heard that the gears above 5.13 make a lot of noise as well as the small pinion gear.

    I want my truck to drive well on the highway and around town yet still be a good off-road truck. I think I am gonna go with the 37's and 5.13's.

    its getting there. but its not like he is putting 7.17's in a D44

    I have seen a D60/D70 with 5.86 and power-loc's do fine, but the OD allows for really deep gears, especailly when coupled with a 37" or more tire.
