For starters I have a 2000 Chevy Blazer with the 6" Rough Country lift with rough country shocks. So I have been searching and searching for some upgraded shocks and can't seem to find any. If anyone with this lift and has upgraded let me know.

 

You probably won't have much luck finding them by application. The best thing to do is measure the compressed and extended length, note what type of ends they have, and look through manufacturer's specs.

What are you looking for in an upgrade? Softer ride? Firmer ride? Better off-road control?

 

Superlift still makes the shocks that came with there 6" lift kit, that could be an option.
