70 GMC C2500 coilover?

[special-K]

I see them. Custom 10nut answered your question. Those are a complete unit purchased as you see them. You named them correctly. They are coil-over shocks and they are an aftermarket upgrade. On second glance, it may be that these are add-on coils to use on existing regular shocks to add the coiul-over feature. I see the clamp, which I doubt would be how Gabriel would have mounted them.

These trucks, not cars, use shock absorbers, as did all US made vehicles that are rear RWD. The term strut comes from McPherson Struts that came along on foreign FWD vehicles, then eventually US brands that switched over to FWD. So it's trucks with shocks, not cars with struts.
