Default 1994 Front Shock Install

I recently bought a 94 Corvette Base Model. The front shocks were worn out so I bought the cheapest shocks because all I do is go for occasional cruise. The front shocks look different than the original Bilstein's .
I bought the OESpectrum brand at O'Reiley's and I can't figure how they go back on at the top, the bushing's are different looking.

Any help would be greatly appreciated.

Thanks

Mike

How can they be different? though they aren't bilstein, they should still have the upper mounting shaft. Care to share a pic of what they look like?

Default Rubber Bushing in Center - It is from the original shock, does it come out too?

Is the rubber bushing in the center supposed to be there, it is from the original shock set up. It didn't seem like it wanted to come out so I left it in there for now.

The stack up is usually


Shock then washer then rubber bushing>frame<rubber bushing then washer, then nut or nuts.

From bottom to top you should have the following, in this order:

Metal Curved Washer
Rubber Bushing
Mounting Plate on car
Rubber Bushing
Metal Curved Washer

Just think of it as a sandwich where the washers are the bread, the rubber bushings are the meat, and the mounting plate on the car as the lettuce between the Ham / Turkey...lol

Thank you. If you look at the 1st and 2nd picture, there is a bushing that is attached to the frame where the shock mount bolt goes through. Should that one be removed as well or does it stay as part of the front end frame assembly mount?

Does this original bushing stay in? It was not part of the replacement shocks hardware.

It's been a while since my C4, but as far as I know, all you need is what came with the new shocks. One of the rubber bushings should have a step in it that will fit into the hole. This isolates the shock shaft from the frame when the two bushings are squeezed together.

I actually think they are supposed to bulge to a matching diameter. No?

Should be they bulge a tad past the diameter of the large washer.

Check the instructions that came with the new shocks. Most I remember doing had the installer tighten the top nut till the bushing compressed and expanded out to the diameter of the washer both above and below the shock chassis mount.

I assume yours is like mine: don't overtighten the nut initially. Snug it initially loosely then push-pull the shock a little. There should be a small shoulder on one side of each of the bushings with it towards the chassis hole side, you want them centered in the chassis hole they go through. Once centered, then tighten up the top nut to the prescribed tightness.

There was no directions in the box the shocks came in. Arggh, thus this thread.

This ^.

Concave side of "metal curved washer" goes against the rubber bushings. Rubber bushing have small shoulder that goes inside the hole in the frame. Tighten nut until rubber bushings expand to same diameter as metal curved washers.
