    1 ton axles - do I still use the 1.5\" spacer

    Yes, I searched - went all the way back to 2001, in fact.
    A lot of the guys using 1.5" spacers are running 10 and 12 bolt rears.
    I have a d60/14 bolt.
    Is the difference in track width still 3", so that I would need to buy 1.5" spacers?
    I plan to buy from Perfomance Wheel and Tire.

    I believe that they are still short. The only axles that are the way we want them is the van. be it 1/2 ton or 3/4, 1 ton

    Re: 1 ton axles - do I still use the 1.5\" spacer

    I know the rear is still shorter than the front - I can tell that just by eyeballing it.

    From memory, it seemed like the 1/2ton fronts are 67" WMS to WMS and the 8-lug 3/4tons and the Dana60 are 69" WMS to WMS.
    That is why I am asking. I don't want to get the wrong spacer.

    ANyone out there in k5 land have a 8 lug (or preferable 1 ton) setup and run a spacer? I just want to verify the 1.5" thing.

    This from the D60 Bible recently posted:

    </font><blockquote><font class="small">In reply to:</font><hr />
    All SRW Chevy D60s are 69" wide wheel-mounting-surface to wheel-mounting-surface (wms-wms). Most SRW Dodge are 67" wide, although some are reportedly 69" wide too. A Dodge DRW D60 is 75.5" wms-wms.

    [/ QUOTE ]

    The C14 FF is 67" WMS to WMS. Total difference front to rear is a paltry 2"...I don't run spacers, mostly because it keeps the tires from mashing sheet metal in the rear.

    Here's the info you need It's a review. But to answer your question, yes, you'll need spacers (or a van 14 Bolt FF) to line up your rear tires with the fronts even with 1 Ton gear. [​IMG] </font><blockquote><font class="small">In reply to:</font><hr />
    You can tell instantly when the wheel is installed. The wheel and the 1 ton hub are now closer.

    Re: 1 ton axles - do I still use the 1.5\" spacer

    Rene, thanks for the info.
    So, My d60 should be 69" and the 14bolt should be 67". That means each side is 1" off.
    If I used the 1.5" spacers that people are recommending, I would then be at 69" front and 70" rear, each side being 1/2" off.
    It doesn't seem like that is a big improvement, being 1/2" closer to equal.

    Has anyone run a 1" spacer before?

    Re: 1 ton axles - do I still use the 1.5\" spacer

    Z3pr, I know I would need a spacer to have them line up.
    I'm trying to figure out which thickness spacer to order. I think the choices are 1", 1.25", 1.5", 1.75" and 2".

    If the previous information is correct (and I have no reason to doubt it) then running a set of 1.5" wheel spacers will actually make the trackwidth closer to being equal by 1/2 inch on each side.

    Does anyone see what I am questioning here?

    To my understanding the front axle is 3" wider then the rear axle, so that would be 1.5" spacer on each side. The review link in my prevous reply was on a Blazer with 1 Ton axles.

    I run 1.5" spacers in the rear... track width is (now) even... yes, I have a D60 and a ff14b.

    Have you measured overall width front and rear or are you going by eye J-man? Your rear should be 1" wider than the front now if you used 1.5" spacers.
