What inner tie rods are these?

[DARIN 510]

Does anyone know what inner tie rods these go to ? I wanna build my own for a turd that I’m working on. Could it go to a Volvo? 280zx?

There is a cross rod that ties the idler arm and the pitman arm together. On the ends of the cross rod are a left and right side rod assemblies to the steering knuckle. From right to left....

 

Right knuckle, outer side rod, side rod bar, inner side rod, c  r  o  s  s    r  o  d, inner side rod, side rod bar, outer side rod, knuckle Left

 

They don't look like anything for 510 steering. Everything on the 510 has castellated nuts with cotter pins.

Oh sorry I did not specify. I would like to make some adjustable T/C rods.

I don't know what source Futofab uses, but I made some years ago with Mitsubishi Galant (1999-2003) inner tie rods.  I had access to some used ones to play around with.  I have never installed them, but I do recall being a bit concerned that the stub thread was going to be a bit short for the washer and full size nut when attached to the body.  I would make sure of that before you decide.  

 

Probably not all that important which you choose as you will have to cut the necessary thread on the shaft side to match the sleeve.

Maybe you can use this to find a better match.  

 

I wish I knew this existed 5 years ago!

Tension rods not inner tie rods.

 

Tension rod as it is under tension. Forms a strong 3 sided triangle with frame, tension rod and LCA. Prevents the LCA from being pulled backwards when the brakes are applied.

Well now I'm completely confused. Tension rods or steering components?????

Futofab and Emrish use parts from a inner tie rod end to make their tc rods. That’s why I was asking for info.

I seem to recall BRE used MGB rack and pinion tie rod ends for their tension rod monoballs.

Makes sense.

"FutoFab uses a rack end from a late model Volvo with power steering."  

 

From the man himself.

Thank you guys.  Very helpful 🙌

They are talking about rack & pinion INNER tie rod ends aka inner ball socket, off of a different car..............not the same as the four required 510 tie rod ends OR the two outer tie rod ends on all other cars!  The ball socket bolts directly/rigidly to the tension rod mounting bracket at the front, the tie rod pivots in the ball socket, allowing for suspension travel.  It is NOT a soft mount like the OEM, but it also NOT a solid mount like the poly replacement bushings which often cause the OEM tension rod to break.  I have read Honda, Volvo & now potentially the MGB rack & pinion INNER tie rods ends will work...........??

[iceman510]

Literally almost any would work, it just depends on how you plan to build it.  Most cases you will cut short the inner tie rod end and thread it to what you want to fit the sleeve you are using.  I will have to look at mine again and see what I did.  I made them probably ten years or more ago and then sold the racecar before installing them.

[thisismatt]

Anything would work...stronger the better of course.  Futofab stated in the past that he "uses a rack end from a late model Volvo with power steering."  That's a direct quote.

I used 280zx inner tie rods for this function for my personal build.  The difficult part was finding a nut for the threaded stud that would usually go into the steering rack.  On the 280zx the thread is M16x1 (not a very standard size).  After much research, I was able to find a stock Honda powersports nut with that thread.  The Honda p/n is 90203-KM1-020 for the M16x1 nut.  Here is a picture of my T/C and LCA setup.

Do you know what the thread pitch is on the outer portions ? The part that threads into that tc tube 

[iceman510]

Not answering for Duke, as I don't know what he used, but typically you can choose that since you have to make the tube and nut assembly, and cut the threads on the tie rod end anyway.  When I did mine, I used 14 x 1.5 since that matched the thread on the tie rod end (rack insertion end as mentioned by Duke) so that all of them would match.  This is also a typical size used on inner tie rod ends where the outer tie rod ends/ball joints thread on.

I profess my ignorance to a ball joint tension rod. I see why it's adjustable but what is the advantage of a ball joint over the rubber bushings.

Yah I noticed that too

It has a better articulation and no binding that could cause the rod to break. 

[datzenmike]

The stock ones move fine and only break if you replace the bushings with poly.

Like duke's, combined with adjustable lca and a clevis point attachment at the lca it allows unbound adjustment of the triangle? It's more solid while more freely moving?
