I know that. I was asking what they might do if you put them on an 08-09.
They will fit on the 08-09.
In a stationary position, (on your trailer), they will bulge the track slightly, but understand, the biggest benefit is when your front arm and or rails are collapsing from snow pressure. That is when you see the biggest curvature from the track. It has nothing to do when it is stationary.
Remember, it is called a powder wedge for a reason. It is not intended for high speed trails.
