could use some advice on wheel adapter issue

i have a 96 1 ton chevy that i converted to 99 3/4 ton hubs to tuck 22" frl. rims in the front. the issue that i found was the adapters that i have (unknown make) hit my calipers, i used a 1/4 spacer to solve this issue.. here i am about 4 monthes of driving and i snapped 4 wheel studs on one side!! thinking old studs, i replced all with new, about 4 monthes later snapped again!! the studs are the same size as the 1 tons so i think the issue is in my spacer. my adapters are hub centric but because i needed the spacer it now relies on the studs only. as far as i know all adapters are hubcentric but the pics of yours look like they are bevilled for the hub lugnuts? the only thing i can think of doing to fix this is to drill my hubs for 5/8 studs and drill my adapters to accept an acorn type nut. do you have any suggestions? thank you in advance.... chris. by the way, Merry Christmas to everyone!!!!

i know the 3/4 hub has been done over and over, what am i missing? i only changed the hubs, are the calipers different?

160 views and no help?? No one has ran 3/4 ton hubs?

Scooter, The 3/4 ton rotor is the same as the 1 ton SRW rotor so you need to look into the 1 ton SRW calipers. The calipers are different between the SRW and DRW but bolt right up to the spindle. This may sound a lil ghetto but all you have to do is change calipers and keep better than 1/4 pad thickness on the brake pads (just bend out your squealers) and you should be able to go without your spacers. Hope this helps, Darrell

You may want to check the actual hub bore on the 3/4 ton stuff. We have had some cases where the hubs on the 3/4 ton were slightly bigger than the 1 ton. Your Chevy should be 4.567" and the 3/4 ton may be 4.60, not very much but enough to make a difference.
