    Watts link geometry questions....


    Support FSC and see no ads! - Click Here
    I'm planning on making my own watts link and have gotten a good majority of it figured but I'm having a hard time finding any info about ideal geometry.

    There are lots of references to them on the net but nothing regarding setup and ideal geometry.

    Any example of what I'm looking for is...
    - Should the 2 bars be paralel at ride height?
    - At ride height should the bars be parallel to the ground?

    Any links or info anyone has would be appreciated....none of my chassis and suspension books really go into them at all.

    I would assume the bars should be parallel at ride height. Just like the 4link and panhard, they are all suggested to be parallel(or level) at ride height.

    Re: Watts link geometry questions....

    heh...Good luck. The guy who did the install on Brian's lime green truck made one and after a couple months, Brian had nothing but hell with it. Of course, I would trust your competence with this job more than I would the guy who built his.

    Re: Watts link geometry questions....

    Oh yeah....BTW, is there any formula or specific recommendation for how tall the center "diamond" should be? I don't forsee any issues with the planned one but it's just something I'd like to know.

    Re: Watts link geometry questions....

    sounds like a lot of math, but i bet it would be worth it in the end. Any suspension books yall reccommend?

    Re: Watts link geometry questions....

    there are some good books ive read that have good articles onthem.. However there is alot of math involved to get it set up right. Main reason why i never got into building one right now.
    U ever think of getting the tp setup and then getting measuremnts for yours? You could always resell it.

    And the whole attraction to the watts link is that your axle won't shift from side to side when you raise and lower the truck.

    Re: Watts link geometry questions....

    LOL satchell link is the correct name of a tri-4-link anyways my book tells me why to run one and to remember the load on any rear axle lateral control system can be over 2000lbs with a peak loads as high as 10,000lbs. In the photo of the watts link it showns the bars bolted at 12 and 6 at ride heigth the only other metion of the watts is to make sure to move axle full range to make sure there is e-nuff rotation

    In all honesty they are really simple. Your way overthinking the application. The center should be straight up and down on the exact centerline of the axle at ride height. It'll never leave that centerline as long as your two bars are the exact same length. The ends of the centerpiece will just tilt to either side as you go through the range of motion. The only real figuring you need to is to make sure that there is enough articulation in the bars so they don't bind across your range of motion. It's just like every other piece of racing equipment that has been modified for street use....there are comprimises. Like a 4 link, the longer your bars are the less of a change your center piece will rotate through, but since the frame is only so wide, you deal with what you have and compensate for it by allowing the center to articulate enough around it's axis.

    I hope tha you do make one. They are super nice and relatively simple.
    Never argue with idiots, they drag you down to there level, then beat you with experience
