About 30k on the struts and 10k on the springs. Struts also come with manual remote damping adjusters for the rear. Also spacers to avoid saggy butt included. Lastly, there is some wear to the threads of one of the rear struts, but it does not affect performance or the ability to tighten the top nut because i just added another spacer to avoid the damaged threads, and I ran it like that on the street and lots of autocross, and it's all good.
