Can anyone tell me the difference between these?

 

rears - nothing

fronts - 4x4 are larger diameter where they fit into the hub

 

Aren't the rears different as the 4x4 rear arms are narrower where the shock absorber sits?

 

About 1/4" narrower, on bottom eye but can't rememeber which ones which, just the difference.

Thought it was that.

4x4 ones are narrower. Just been out and measured the ones on my 4be and the 2000e (2wd).

 

well they do say you learn something new every day.....

 

I remembered that I had top put some shocks in the vice to cut about 1/8" of each side of each eye, to fit on a car.

Cossie rears are all the same. Be it RWD or 4x4. However, the bottom mounts on a standard (non-Cossie) RWD Sierra is about 8mm wider. Can be modded ofcourse by just grinding of 4mm on both sides of the bush and AFAIK standard Cossie shocks are shorter because a Cossie was lower compared to standard Sierra's.
Fronts are very different. AFAIK the 4x4 shocks are shorter than the 2wd versions because of the hub that is also very different on both models.
Not sure about the diameter differences.

 

I still have clearance issues with tyre shoulder touching shock spring platform - this is why I'm asking about the shocks. Could my car have the wrong hubs on etc. Could something to do with the shocks or hubs cause anything like this.

I've been through the wheel/tyre/etc issues so many times. Yes I think the offset is right, wheels are 7.5 x 17" with 215/40 rubber BTW.

 

the 4wd shocks are thicker on the front where they go into the hub
if you had the wrong shocks you'd soon know baout it
