    Re: HELP PLEASE ! what size r stock u-bolts and tires ?

    You can use stock rear U-bolts to interchange with the three "short" front lift spring U-bolts.

    I believe, for stock application, the long front U-bolt is 10" long. I'm pretty sure the lift spring one is 11" long.

    In the front, a factory 3 leaf pack is 5/8" shorter than my 4" BDS pack.

    Just don't forget to buy 5/8" diameter U-bolts when you buy new ones.


    My truck came with 235x75r15 tires from the factory.

    Darren, the lengths are posted above. Get the U-bolts for a 3" axle tube. As for tires, get a set of 31x10.50's. They will look nice on the newly shorter ride.

    Anything you don't have call me, I might have it.

    My door has a sticker that says 10R15 tires , so it would be a 31 " stock if you have optional rims etc . Some came stock with 235/75/15 on the lower models /forums/images/graemlins/k5.gif
