Especially cheap ones? It doesn't seem like long ago, but it's been 23,000 miles since I put on my $17 ea. KYB shocks. They've felt kinda soft ever since I put on new struts - would it be safe to assume they're shot?

 

I have those same KYB's and mine are soft after 10,000, Miles, Infact, Im pretty sure thy were soft to beging with.

Moral of the story, You get what you Pay for!

Livin' the Stereotype

 

Man, I put those damn KYBs on my car and THEY SUCK. Everytime I go over a speed bump the back end slams down and sometimes it bottoms out. My stock Bilstein's that were 100,000 miles old were better that that. I think I'll be going with Bilstein's in the very near future.
But to answer your question, most shock last between 40,000 and 60,000 miles.

I would say every 40,000 look at your shocks bushing and mounts. Springs they say last a lot longer, but I say no longer than 90K for them...
