I searched and didn't find a for sure answer so bear with me. I may be getting a stock 98 blazer 2 door. I plan on cranking the torsion keys up and blocks out back and running a 31...I like dick cepek wheels dc2s. What backspace would I need i don't want them sticking out a mile and 15 x 8 would be what I'd want I'm sure?

 

Would these fit? Not sure on the offsets

Those will probably stick out pretty far. Assuming you're getting a 4x4 the stock backspacing on the wheels is 6" and the backspacing on these is a little over 3.25" meaning that not only are you getting a wider wheel, but you're also putting them out further due to less backspacing. Oh, and blocks in the back will lower it since the axle sits on top of the springs. Buy some 2" lift shackles, they should give you enough lift to fit 31's. I have 265/75r15 on mine and they measure around 30.6x10.5 and they fit just fine.

 

Dang ,so I need about 6 inches of backspace to get them to fit properly. A 8 inch wheel will be ok? Where do u buy your shackles

 

You can go with less backspacing, just realize that it's going to put your tires out further. An 8 inch wheel will be fine. And I bought my shackles off ebay. They shouldn't be too hard to find, just takes a quick search. I think my shackles were about $40.

 

What are most people running with a 8 inch wheel and 31s? For backspacing

 

I don't know. But it all depends on how far out you want your tires to be. With a 8 inch wheel (+1 wider wheel) and 6 inch backspacing (OEM backspacing) the outside of your wheel will be an inch further out. So it's all personal opinion on how far out you want your tires to be.

 

What's the specs on yours the blue 2 door looks Nice and how I'd want mine

 

It's a 2001 2wd. I have 2 inch lift shackle in the back and spacers on top of the coil springs in the front. My wheels are the stock wheels that came with it, just painted black with plastidip and the tires are 265/75r15 Cooper Discoverer AT3. You can read through the build thread if you want to read about anything else I've done to it. Oh, and the spots on the wheels that aren't black are just where the old weights were when I went and got the new tires balanced. I haven't had any plastidip wear off.

 

Looks great I like it!!! Thanks for the help
