I have the 412 progressive shocks with heavy duty spring that are stock lenght, 12" I think. I have to agree with Martin about the picture of the stand on Newspeedmaster.com. My stand has a rubber bushing thingy on the arm. I quess to protect the exhaust pipe when coming off the stand. I was afraid it would contact the hot exhaust and melt or burn, but it has about a good 1/2 inch of clearance in it up position.
