I finished my 4in SL lift and when I put my new rims on the "1/2RH" lug nuts work fine on my front rims, but on the rear the nut bottoms out before it gets to the rim. Are the stubs different lengths?

The wheel studs may be different lengths. I do know factory acorn style lug nuts are long enough for most wheels. The thickness of your wheel will make a difference also.

I moved this from tech corner-

Thanks.

You must have at least 5 threads of engagement of the nuts for safety, check that. The spec is the length in threads to match the stud diameter, so 1/2" of stud threads. Good luck,
