Whats the difference in rear shocks off an 07 Road Glide compared to an 09 Road Glide? They look the same on HD's site but have a different part number.

 

Hey man, from what I understand it has something to do with the internals. I am pretty sure the suggested psi for different loads are different from year to year. Also, I spoke with someone from Progressive when I was looking at a set of their shocks that someone had on an '08. I was told that they would bolt up, but the 09 would bottom out with pre-09 shocks
