Same spring they use on there Wedge head. 1.55 single spring and damper, about .550-.590 max lift.
Nothing special thats for sure, any kind of perfomrance upgrade over stock stuff will get these changed out.
I have lots of info and flow numbers for these too.



there you go, same as on the Wedge RPM head. Nothing fancy going on there.
