I have been talking to Steve Fox and a few others trying to find info on this subject and was told that you are running this setup. The topic keeps coming up on the board but there doesn't seem to be a definitive answer and I'm hoping you can help. I know there is grinding required to clear a Dana 60 caliper. Two big questions would be what brand steel wheel to use and is the grinding excessive or dangerous??

Steve said that there was about 1/8" clearance between his 16" cast aluminum wheels and the D60 caliper. Considering that the alum. wheel is much thicker than a steel wheel and that there is only 1/2 inch difference in the radius of a 15 & 16" wheel, there shouldn't need to be alot of grinding, should there??

Thanks for any input you can give

We've had good luck with Stockton wheels with 3" of backspace. They still require some grinding, but it's in the neighborhood of .080" maybe? It's not major at all. I'm kind of squemish about grinding on a caliper and it didn't bother me at all. In fact on one we used a little sanding wheel, so it's not a big deal. You end up with a REALLY WIDE track if you use wide rims though. I've run 8" wide with 3" backspace, and currently have 11" wide (10" with beadlock) and 3" and now it's really wide. With the 8" wheels the track was just how I like it, a couple inches of tire out of the fender. It doesn't look bad or attract attention, but it keeps the rocks and trees off the body pretty well.
Hope this helps

I keep hearing this only works with a single piston caliper. I looked at a d60 in a scrap yard here and it had dual piston calipers. It was also a dually. are single piston calipers common? what years used them?

your right. I don't understand the jeep thing!

Thanks Brian. How's the weather on the rock?

I can't remember but what is the normal backspacing for the rims?

Hi Joe!

Lots of snow here on the rock! I hear you guys are getting your share as well!!
I don't know what's considered "normal" for these wheels (maybe Stephen or someone else knows) but most of the different brands of "off-the-shelf" that I found had between 4" - 4.5" backspacing. I guess that's why some guys have to grind so much off the D60 caliper to make it fit.
The wheels Stephen has seem to be the answer.

Take Care

We're guessing factory backspacing on a 16" steel wheel is about 4". That's for the 6.5" width.
