The shock is a Dnm's Dv-7 , 750 lbs/in. It's on a cheap but ok mongoose mgx grx 6.5 bike. I know it's not the best bike around , put it's gone through hell of a lot. I've already upgraded the fork. from an rst 281r to a manitou magnum r (which i just busted, warranty fix). Upgrading the brakes to some avi's etc... Anways, I'll do just like you said, thanks!
