Stern does install protectors on most of their ramps which they didn't used to.
But as far as scoops and things like that...I can't imagine them doing it. I love cliffy (and support him often) but think about it...
Back in the day, I believe someone said the machines were built with an anticipated 2 year lifespan. They are built to wear. From Stern's side (or any mfr) obviously they want people to buy new machines.
