I think that I'm second guessing myself. Will 5.13 Yukon gears and full spool handle a 390 and up to 42 inch TSL's in my rear D60 with 30 spline shafts?

I bet the gears and spool will be fine
the 30 spline shafts will not

gears and spool, no problem. The guys' are probably right on that rear 60 though, unless you drive like a sissy ;)

yeah, gears and spool, no issues.. the rest of the axle, especialy the shafts.. good luck. I'd upgrade to a better rearend personaly.

you run empty and keep the weight down, the axle's will take it for quite a while, and the spool will help by making sure both sides get even abuse:D ... I run a pretty stout 390 with 38.5x15 boggers on my crewcab and haven't broken the 60 yet and i never worry about breaking, it'll just give me an excuse to put in the 10.5" sooner......

Plans are to take off the bed and shorten the fram just a bit in the rear. I take it that getting a little of the weight off the rear end would help....for awhile. Currently running 36's but I'm planning down the road.
Thanks guys.
