I have a Wilber's shock on my GS_PD, problem is I have no information about this unit, like what type of spring it has, medium, hard, very hard. How to adjust the unit, etc, etc, any help would be appreciated.
I would like to change the spring for a harder one, my unit has numbers on the spring but don't know the meaning of them.
