The Pro sits high in stock form compared to most mtn. sleds so not needed. I was pleasantly surprised at how much less I got stuck with the Pro than any other sled I've ridden and even then, I could always get her out easily. Never trenched down so much as to wish I had them and yours is the first post I've seen regarding that issue for the Pro. Now for BRP, that's a different story and I have a set of Smitty's drop brackets for sale!
Have FUN!
