Re: weld it or clamp it

This is the route I'd go...used it for my steering stab on my 1 ton steering setup....works very well

You could use 1 side to mount the stud for the ram, and the other side could be used like a set screw for additional clamping (altho I'm not sure it'd be needed).

Re: weld it or clamp it

I wouldn't weld it -- What is the alloy of the tie rod? -- how about the bracket?

Clamping to aluminum just makes sense here

What is the worst that happens, you clamp it and your clamp moves -- if it doesn't hold then you need to weld it

why is welding is the backup plan rather than the plan? curious why you wouldn't do it right the first time...

What alloy is the aluminum? Not all aluminum is weldable.

Re: weld it or clamp it

I had a buddy that used a clamp for his hydro-assist, and even though the clamp was as tight as it would get, when we were on the Rubicon it continued to rotate. If you go the direction of using the clamp make sure there is something that the clamp can grip to vs just the smooth tie rod. Lay some small beads down to create some ridges, or cut some groves in it, so the clamp is not having to grip to a completely smooth surface.

Re: weld it or clamp it

i will start w/ a clamp & see how it goes, if it moves maybe add a couple tack welds on each end of the clamp.

Re: weld it or clamp it

If you use that clamp, you can machine/grind a small flat spot on the bottom half and use the 2nd threaded mounting point as a 1/2-20TPI set screw........

And follow the directions on the website for hydro assist

Welding to unknown aluminum alloy is tricky — do we know the alloy

Are any of the parts hardened? The heat from welding will change that

Personally I wouldn’t want that small “hot spot” on my tie rod could easily cause a brittle spot

Here’s a thought — are we talking an iron man or stinky fab aluminum tie rod — give them a call — I’ve spoke to Andy at iron man before and I know he’d be happy to talk about connecting options on one of his aluminum tie rods — I’m sure it would be the same with Dallas over at stinky fab

That's 7075 aluminum which is not weldable (with traditional techniques). The composition of the alloy makes it develop super brittle areas around the circumference of the weld and ultimately will crack every time.

Its unfortunate because 7075 is a great alloy.
