Ubolts for 31 spline
anyone have any good sites where they have Ubolts for decent price? I know i can have Evan (rangererv) pick me up some or might beable to find a place local but thought there might be something online.
it was my understanding that the 31 spline is 3.25" in diameter.
im hoping to find some Ubolts that have enough thread on them to use with my current configuration, and for when i plan to reinstall my 2.5" stock blocks, but maybe this isnt possible?
thanks

You could use Level II U-bolts for a 31-spline with the blocks but the threads do not run far enough to run those without the blocks - unless you resort to some goofy washer/spacer arrangement on the top side of the spring plate. Seen it done - wouldn't do it myself.
You might be able to find universal aftermarket U-bolts with enough threads to do run with or without the blocks. I think that they typically have a longer threaded section. Last time I priced them, OE U-bolts were about $16 ea and aftermarket were about $12~14.
Correct - the 31-spline axle tubes are 3.25". Dont forget that the factory spring plates are also different for the larger tubes.

thanks bob, i just got these in the mail today...
not sure if they will alter which type of Ubolt i will need or not, might effect the over all length of them but they are massive.
I'm trying to get an overall good guess on these because when i go down to get my 31 spline installed i want to do it all in one day. and not have to rebuy another set when i install the blocks, but maybe i dont have any choice.

Don't forget about the spring plates. You posted the spring perches. The spring plates go over the springs and that's what the ubolts go through and the nut tightens against. Do you have the larger ones of those that you need?
Also the 31 spline ubolts are larger in diameter than the 28 spline. I'm pretty sure I posted on that somewhere on here, but I don't remember the diameter off the top of my head...Bob?

well since this thread is turning into whats need to get this under my truck...
this is a 91 explorer axle with drums. im basically replacing/rebuilding it. will my current ebrake cables work with the new axle?
also is the brake line from the top of the pumpkin to the frame rail setup basically the same?
