Default C2 Steering Stabilizer (shock) Question

I noticed that some small block 1967 Vettes w/o power steering have a "Steering Stabilizer installed between the center Link and the frame. It looks like a shock absorber right in front of the oil pan.

What it it's purpose?

Why were they not installed on non-power steering Big Block cars? All the mounting holes for it are there for one.

I know a person who installed one on his big block car and was wondering what benefits it provides on a big block car.
Does it enhance the steering stabilization?

Thanks!

It eliminates caster wobble. Caster wobble will cause your steering wheel to vibrate (rotationally, not up/down or side/side).

edit: caster wobble is like the wobbling front wheel on a shopping cart.

If you don't have caster wobble without the shock, it isn't doing anything.

On the Corvair, they just added friction in the lower ball joint to kill the wobble.

Apparently it didn't really help much, or they didn't really understand the problem it was supposed to solve; it wasn't used at all after 1967 on a chassis that was the same from 1963-1982, although the relay rod (centerlink) diameter was increased for '68 when the stabilizer was discontinued.

I am putting factory power steering on my 63. It has the dampener/stabilizer on it. Should I remove it?

Sure. Power steering hydraulics acts as a damper. If your steering wheel vibrates, put it back on...

You'll HAVE to remove it - the (stamped) frame bracket for the damper and the (cast) frame bracket for the power cylinder install in the same location, using the same bolt holes, and there's no provision on the power steering relay rod to attach the damper.

Probably a dumb question John: my damper has a very slight leak, and, I guess the $115 question is, would you just leave as is, replace, remove? Thanks

Unless you're itching to spend that $115.00, I'd ignore it; the damper is simply a horizontally-mounted shock absorber, and doesn't serve any critical purpose.

John: My original 68 came with the damper. It is a March 68 build. GM must have had a few left over from the 67 run??? Jerry

I was thinking the drag link diameter changed in '69 but I could very well be wrong.

Does it show in UPC 9 in the '68 Assembly Manual?

10-4! some ncrs type came by the house a few years ago looking for a '68 drag link. Said it was smaller than the later ones. He saw one I had laying there and said that's what he needed so I was glad to oblige! I figured since he had his club jacket on, he knew what he was talking about!
