Welcome to the new and improved Proflex / K2 Tech Forum!
I have this shock sitting around and it needs a new home. It has seen little use and is in like new condition. No leaks and works like new. Has the rebound adjust which makes a big difference to the feel and to match the spring rate. The spring is NB2-600 and I also have a NB2-650 for it as well. It game off a 4000 so should fit any of the EVO type frames. I'd like to get $125 USD plus shipping. I'm in the USA.
one just ended on ebay off a 4000 went through auction a whole week then sold with one bid for $20.00 plus $7.95 shipping
i like my fox rp23 but i kinda wish i found your shock first. i think i would have paid the buck and a quarter for it, it does look like its in great shape, and thats the spring rate that my fat butt needs. i have been looking for 6 mos. for a heavier spring for my stock noleen and didnt find one. i found the fox, but i bet your shock would hold up much better if i did any jumping. oh well.
