    I need some backspacing help for a Dana 60 and 14B FF. I'm not sure what to look for in rims to fit these axles? I am either going to get a 16 inch rim or a 15 inch rim and then grind the caliper. So how much backspacing do I need so rims will fit these axles? Thanks.... /forums/images/icons/smile.gif

    <font color="green"> 16" rims will fit with whatever you want, up to like 4.25 or so. With 15s you can go anywhere from 2.5"(no grinding, well, maybe a tiny bit) to 4.25(Buy a few new grinding wheels and set aside a day). 3-3.5" seems to be a good compromise. </font color>

    If you decide to go the 15" route, this might help a little...

    Giving up on the 1/2 ton build up? Sounds like you've already got the axles, guess I missed that, I've not been on too much lately...

    I'm gonna try to get to the point of running spots in the Rubicon on the rocks. When I was considering 35's it was cool with 3/4 ton, but I wanna go with 38's and wanted 4.56 gearing instead... changing out the gears wasn't worth the cost to me, and like I said size wise that's pushing it to be on rocks... I don't have em yet, but plan too soon...

    I recall someone posting that the factory backspacing was only around 3.75", I never confirmed that so wieght it as total heresay.
    the correct BackSpacing depends on your tire diameter.
    a taller tire would require less backspacing then a shorter one, the object being to get the scrub radius low as possible.
    draw a line from th upper balljoint through the lower ball joint and the point where that line hits ground would ideally be the centre of the tire contact patch
