    Its normal im not sure on exact measurements but the front 10 bolt has a wider track than the rear 10 bolt. Nothing to worry about /forums/images/graemlins/thumb.gif

    Is there any purpose to getting those spacers I've seen here? do they improve the handling in any way or is it a cosmetic fix only?

    Basically cosmetic.
    Some people say that GM did it for turning radius purposes - I have not read anything believeable about this yet however, and can't think of how it would work. /forums/images/graemlins/crazy.gif
    And some people will say that lining up the rear tires directly behind the front ones will help out in the mud and deep snow...to that I say "bull puhy"...if that's the reason you believe your truck runs through the mud and snow so well, than you've got another thing coming.

    Pure speculation, but I'll guess that it was done to allow the same wheels (backspacing) front and rear, while allowing the tires to turn a reasonable distance, without rubbing. Of course, with the stock 235/75R15 or 31's, I can't see how the tires would even be close to rubbing.

    On the snow/mud issue, I have to disagree, running in virgin snow is a lot easier (better traction) than running in existing tracks. At least from what I've seen/experienced, existing tracks serve to make the snow "ice" whereas the virgin snows still affords some traction. Much more dependent on tires I'm sure than wheel placement though.

    Well, I agree about that with the front - but it still doesn't answer the question "why didn't they just make the rear 3 inches wider?"

    I think that if you re-read my post, you'll find that you're agreeing with me. I said that some people think that lining up their front and rear tires will help them out...but I was saying it will not. Maybe my wording was'nt very good.

    i think there are real-world benefits of having spacers. I always found it annoying when i went wheelin pre-spacers and my rear tires would slip'n'slide into the ruts that my front tires were going straight through. its not the end of the world... it was just annoying. Pretty much an unecessary loss of traction. Secondly, having a wider track width = more stability. Sure, its only 1.5" on either end... and the effect on stability prolly isnt THAT great, but still. Considering all the things we ck5-types do to our rigs that make them less stable, i like the idea of doing something every once in a while that actually helps. /forums/images/graemlins/smile.gif
