    Ok,heres one for you guys,got a brand new,in the crate stii,hpd60 front,and am going to run a 15 inch rims by12-14.i was told from a guy,this wont work,(he works at a 4x4 shop here in town)he said hes heard of many people grinding the callipers,and significantly weakening them.i am buying some 38x15 tires,from a friend of mine and thats what i have to work with,and a 15 inch rim.the guy said most all the time the calliper will fail,leaving me stranded even if it is just enough to clear the rim.has anyone here ever broke ,or heard of anyone breaking these callipers after grinding? /forums/images/graemlins/confused.gifis this a common problem? /forums/images/graemlins/confused.gifive read the tech section already,just wanted to know first hand.YOURS TRULY HI PINION again, thank you

    I ground mine when I went to a 3/4 ton Dana 44 front. No problems whatsoever, and I'm not very concerned that it ever will be. There is plenty of material left. My Blazer is my daily driver, and I wheel often with my 3 kids. I ground them last July.

    Hope that helps!

    I ground my 1 ton calipers on my D60 to accommodate 15" rims about a year ago. I have no braking problems at all. The calipers seem to be quite huge and can hack some grinding...please note that it is no short task to grind them...it took a few hours to do both sides.

    If you ever bring your truck to a garage to have the caliper replaced they might have a hard time figuring out why they cant get the tire back on LOL

    If you're running Chevy outers and Chevy calipers it'll be fine. If you're running the Ford dual piston calipers I don't even think it's possible to run 15's...

    That sounds like a b.s statment, with the amount of people on here, I have never heard of such a thing and I'm on here alot! Sounds like he would also be the person to say "I once had a stock jeep I took that thing everywhere, she never got stuck" He probably even has a stock truck or a cookie cutter Z71 or maby a cute jeep...that goes any where /forums/images/graemlins/rotfl.gif

    I ground my calipers, but I had to grind less than most people because I am only running 2 1/4 or 2.5" inches of back spacing, I can fully tuck the tires in the wheel wells and I like the look so it is all good for me /forums/images/graemlins/thumb.gif I was done grinding in way under an hour /forums/images/graemlins/thumb.gif

    That's exactly what I told him yesterday in the PM he sent me.

    This is a common thing with Chevy axles and can be done with no issues. I've heard of people running anywhere from 4 1/4 to nearly no backspacing.

    Mine are ground just like that article. I run 15x10's with 3.5" of BS with no problems. I have had all 4 tires locked up in full panic mode with 40's and haven't had any trouble. I also did not hesitate to drive it 1200 miles each way to Moab...wheel the wee out of it etc, and I certainly didn't have any troubles or worries.

    The guy is full of it IMO. GM D60 calipers shouldn't be a problem. Just make sure you use steel wheels, no aluminum. Also, some wheels require more grinding than others depending on back spacing and shell profile. More back space means more grinding. I'm running over 4" b.s. on mine with no troubles. Profile is another matter. I've never seen a steel wheel that was bad enough to cause a problem, but some claim they exist...

    besides, if you ever get more involded or get in deep you can one day decide to convert your wheels to beadlocks /forums/images/graemlins/deal.gif or not..what ever floats the boat /forums/images/graemlins/thumb.gif

    I had a friend in a Jeep slam into a canyon wall at over 35 mph, he turned two aluminum rims into a two piece rim! Cracked right in half, darn thing looked like a hubcap /forums/images/graemlins/eek.gif

    I had aluminum outlaws...they were off the truck in less than a month /forums/images/graemlins/pimp1.gif

    If cost is a factor go with some black rock crawlers and call it a day. Simulocks are a waste of money...
