Offset and Backspace are essentially two different ways of measuring the same thing... If you want the same exact wheel just tell them you want 6-7/8 BS

How much room do you have on the inside by the leaf spring? I'm at stock rear height and am wondering if the 6-7/8 backspacing will allow a 315.

You should be ok, GMCtrk on here was running a 315 on his 15x10 racestars that had 7.25 backspacing. I think he said it was tight but did clear.

On stock height you'll fit a 315 it's just going to stick out, my 275s fit damn near flush with the side of the bed but again that's on a 5/7 drop

Do you happen to know how much it should stick out with 315s?

It's completely dependent on what BS your wheels are, assuming you run the same exact wheel I have @ 6-7/8" BS I'd guesstimate less than an 1" outside the fender

Also a member on here by the name oakley6575 has a couple pics of his truck on a 315/60/15 with 6.5 BS to give you an idea of how it would look, the extra back spacing (though it isn't much) on the Cragers would bring them in just a hair more

@ironcityboom - Thanks!

I have been looking at going with some cheap stealies and was not able to find much more than 5" backspacing off the shelf. I followed your instructions and gave Summit a call. The only difference is the agent reached out to Cragar while on the phone with me and was told the CRR-3975160 can only go up to 6 3/4" backspace. I asked about 6 7/8" and they said no-can-do. No biggy as the 1/8" wont matter for me. I've got a 2007 NNBS so I'm going to take a few more measurements once the wheels come in and then I will make the final decision on the rubber. Right now I'm between the M/T 315/60 and 295/65.

$169.92 to my front door. They estimated 3-4 week build time.

Very strange, I was told 6-7/8 was available and went with that. Wonder why they told you 6-3/4

Figured I'd revive this thread since the topic gets brought up alot. If your looking for a custom offset option but don't quite have the funds for bogarts or welds these are an excellent option.

I love this, ironcity. You've convinced me to buy a set for my 89.
