im going to be buying a set of series 51 wheels within the next week now. I still do not know if i should go with the 3.75 or the 4.5" backspace. does anyone have pictures of a 4x4 blazer/jimmy with 3.75" backspace? thanks

 

Get the 4.5" bs, your front end will thank you for it more than with 3.75" bs. Unless you really like replacing front end parts, that is.

 

I run 3.75 on a 10 inch wide wheel, no rubbing issues

 

bad350v8s10tahoe:do you have a front or rear view picture of your truck?

 

I rub 30x10.50s with a 2' BL and the tbar crank+shackles, and I trimmed the fenders. I've got the 4.5' backspacing. 4.5' made my steering start groaning after a few hundred miles. Threw in some lucas steering fix. But with 3.75..it'll be worse. And you'll look like a frog, instead of just a wider stance
