I got an 05 edge suspension and im ready to put it in to my sled. What is the first step I should do? Do you think I should get the PS3 shocks rebuilt? I was told that the skid had 1900 miles on it. The skid is in very nice shape. I think I should get them rebuilt but not sure where I should take the shocks. After I take out the old skid what eles do I take out?
