I have never had wheel spacers or a need for them so excuse my ignorance.

Right now I have 1" spacers on the rear. They are the type that bolts to the axle and has it's own wheel studs. These studs are so short and I am used to and like the 3" wheel studs for ease of use. My axle seals are leaking so time to make decisions about wheel studs. So here is the question.

Is there a reason I should have the wheel spacer that has the studs built in vs the the pass through spacer?

Thanks.
Mike
