    Any plans for a complete spring over conversion (drag link and tie rod)?

    We're kicking around some ways of doing that, I'm trying to stay away from running the draglink into the tie-rod since you lose some steering response as the tie-rod rocks up and down when you steer. Doing it that way is a no-brainer, but I'd like to run the draglink to the right knuckle instead. That may not work out, we'll see.
    And really, the D60 tierod is mounted fairly high as is so it's not terrible to start with.

    I just saw pics and an article on a high steer 44 and the steering arm on the passenger side had two holes one behind the other. The front hole was for the tie-rod and the other was for the drag link...
    I can post the link to the article if you like.

    That's what we're thinking on right now, how to run both into one arm and keep all the geometry right. Seems like you might run into some clearance problems on a GM with the draglink behind the tierod, especially on full stuff.

    Stephen,
    I don't know if you seen this, but this was the article I had seen.

    This conversion uses a flat top Chevy knuckle like we already do for crossover...

    I'd be interested to know if he ended up going to a longer pitman arm to make up for the extra length of the steering arm. He could have lost some turning radius and not noticed it in the glow of "newpartitis".
    Otherwise, that looks really clean.

    As always you make a good point, I just thought it was an interesting link. Maybe he just made the steering arms a little longer...?

    would there be room for rear high steer tie rod?
    easier on a d60 and wouldnt it allow perfect ackerman if it clears the springs.

    I think that anything done to move the tierod would only improve Ackerman. They have reverse acherman from the factory and would go more twards parrallel steering if moved to a position like in the link Rene posted.

    What about steering box clearance. I have 4" of lift and with the tie rod above the springs there would not be very much clearance for my steering arm/box.

    Details, details, details. that's what makes the world go round. I don't think there's room for the tie rod behind in a lot of applications due to the oil pan and crossmember. There may be spring clearance problems too. Castor angle is going to drop the back of the arms down to where they may not clear.
    There are a lot of ways to get some extra clearance while still leaving the tie rod under the springs, and you can use a bend resistant rod also. We keep trying to make the trucks more dense and sometimes you just have to compromise. By making them dense I mean dropping weight down to keep the CG low but raising it all up to get more clearance under it. Makes for a lot of stuff in a small space.

    Well, then consider mine DENSE. I wont go over 6" of lift and would only do that if I cant make it work with my 4" lift. Wont do a body lift cause I dont care for them.

    I just replaced my tie rod with a new factory one after bending and rebending the old one. I put it over the knuckles this time, has about 1" of clearance between the springs and the tie rod but it moved the tie rod up about 3" or so.

    "I had to use a 1" spacer to clear the springs...."
    Wonder what that means?

    Also... on a Jeep, the steering box is mounted to the inside of the frame, where ours is mounted on the outside of the frame causing clearance issues with the pitman arm. Titanic has this setup on his Suburban but he moved his axle forward giving more room between the pitman arm and the tierod.
