    I search for this question but, all I came up with is gears. Why is the rearend of my Blazer narrower then the front? if I put 3/4 rear ends in it will it set the same or will it even out?

    The rear is roughly 3" narrower than the front. It has to do with turning radius. The only way you'll get close to the same track width is by installing a 14ff van rear axle. Those are very close to the same width as a front axle.

    I heard of people useing wheel spacers. But I was told that they are prone to break and causing the wheel to come off. anybody used these was towing?

    heard it was due to turning radius, and so that your rear tires dont exactly follow your front tires tread, in theory giving you better traction, but who knows GM has had some wacky ideas. Heard a 1 ton trucks 14 bolt ff will work but no promises

    1/2 ton are 67.5" wide front, 65" rear.
    3/4 and one ton are 69.5" wide front, and 67" rear.

    The van 14 bolts are 70" IIRC.

    oh, so it wasnt just my imagination that the wheels looked further out with the 60 in.

    btw, narrower rear has nothing to do with increased traction, with the rear wheels closer together, you change the center of curvature while turning, making it tighter

    I know we've gone through this before, but different track for front/rear does increase traction in certain environments. Snow is a big one.

    This was true with the old style spacers. I have 1.5" spacers and they are machined aluminum and are quite burly. I had the same concerns as you at first but have had no issues with them in over 2 years. I do check the lug nuts often though to make sure they are always tight, paranoina relly I have not had any loosining of the lug nuts.

    Yea I want to run 2.5 to 3" spacers on my rear and I won't worry about it at all. Just need to find someplace that doesn't want an arm and a leg for em.

    I'd prefer used and around a $75 price tag.
