Anytime...the dampener is an option when you buy the shaft...it is integrated into the shaft. If you go to their web site you may be able to buy it seperately as i think they sell some of the components seperately so you can build your own custom shaft.
I'm out working in the patch so i do not have access to my records otherwise i'd get out the invoice and post it for you.

2wdBlazer...the borgeson shaft is made to colapse in an accident just like the factory unit.
