I ran them most of last season! They worked awesome! Literally twice the spray as my standard scratchers that I have been making for 11 years now. Twice the spray = twice the cool!
I made the Reversible prototypes out of billet 316 stainless and production runs out of cast 316 stainless. The stainless has longevity.
When testing these, I purposely left them in the down position when driving across gravel last June to get to the snowline to see if they would break or wear. They still look great!!
And yes.....they will bolt right into the stock holes on the Pro
