    I have a 91 extended cab short bed, and in the process of installing 2600 dominator bags with a prefab bracket that welds behind the rear end, and the bottom of the bag sites flush with the top of the axle tube. Question is how low will this let me go with the bed empty? Will I need a block to lower the axle more. Am planning on a 2" spindle and ball joint flip on the front with 20x7.5.
    Thanks for any input!!

    Not sure about height, but for my input, you'll likely have almost uncontrollable axle wrap.

    That's what I was thinking also, just wanted a second opinion. What about a three link with a panhard bar? I only want a c notch, do t won't to go into the bed of the truck.

    You can do a wishbone setup and keep all stock locations. You can also do a small real notch and keep the stock bed floor. If your going to spend the money and the time do it correctly. I myself have never been a fan of a pan hard bar, the rear end will have a lot of side to side movement, or at least my experiences... You can also do a reverse triangulated 4 link like Litneon did, pretty clean setup...

    And as for height I'd say all the way aired out you would sit the distance from the bottom of your axel to the ground so maybe about 8"-10" off the ground...

    Can you clarify wishbone with the stock locations? A picture or a link would be great!!

    Yes, that's basically it. It's a modified triangulated 4 link turning it into a 3 link.

    Since the bars on the top of the axle are triangulated, it can't move side to side through it's travel like a system with a panhard bar.

    Do the bars need to be the same length? Does it make a difference?

    It does make a difference. How you drive and what you want out of it determines how much and if you'll notice.

    If you just want it low for cruising and do zero performance driving, no it doesn't matter...much.

    If you want performance and better launches, you bet your life it matters. how long the bars are and the exact positioning makes a world of difference taking off. look up how to position 4-link drag race setups...those cars usually have about 50 places to mount the arms to change the exact angles. There are BOOKS written on the subject.

    Basically, the bar length difference doesn't matter much as far as launching and handling go, the difference more controls the pinion angle change through wheel travel. The direction that the bars are pointed makes a big difference in that regard.

    This is just for riding around, maybe hauling a atv or motorcycle on the back. I had looked at the ends that have poly bushings instead of rod ends.
