View Full Version : OBS top mounted tie rods?

I searched, but I couldn't find what I was looking for... even though I've seen it before. And that's probably because I don't know what it is the tie rods bolt into by the wheel, so bear with me.

So, my truck is lifted a little bit, but not enough to have anything for the pitman arm/tie rods. I keep reading that it's not an issue, but my tie rods are at stupid angles. It looks like it's bent while connected to the assembly. I've noticed a solid lack of drop pitman arms and idler arms; I can find a dropped pitman from a jeep by then still have issues with the idler. So, I remember reading about people either getting the knuckles machines to accept the tie rods from the top or retrofitting the stuff from the NBS trucks.

Has anyone done this or could anyone direct me to where I could read about someone doing it? I'm very interested in giving it a whirl, and would be open to other ideas as well if anyone has come across this issue before. Again, I apologize for my lack of appropriate vocabulary for this, I hope you know what I mean. Thanks!

You realize the geometry exists as it does to minimize toe change during the suspension cycling right?

When you start messing with the pickup points and the changing the the location of the plane the assembly bends in you screw with that.

That makes sense and so I have a follow up question for you. Haven't I already done that? I like the height my truck is at, which means if the guys that installed my lift kit left the torsion bars cranked a little bit then I don't really want to go and drop them. I also don't want to get a bigger lift kit than the one I bought to do it the right way, since that's why I bought this lift kit in the first place.

I continued my search and saw the DJM Suspension tie rod end flip kit that's used on the newer trucks to flip it to the bottom. So I'm thinking that might be my best bet. If anyone's tried it I'd love to hear about it.

All cranking does is increase spring rate, forcing the suspension to sit at a different portion of the travel at rest. It's all still working within the same arcs.

:think:

I hope you are watering it down, unless "spring rate" is an active measurement, rather than static.

Slip of the tongue, err, fingers.

The torsion bar rate is not changed, you're just increasing the preload.

If it was pre-loading the bar, there would have to be no lift, as if there is lift, the bar has not gained any load.

Re-indexing the LCA is about all the adjuster bolts or keys do. Rough ride people attribute to "increased spring rate" is the LCA operating at a steeper angle, reducing it's leverage over the torsion bar making it feel like the bar is pre-loaded or stiffer.

OP, keep your tie rods where they belong, you'll be happier.

Yea, I can't argue that.
