Twosown zero is right, 4600’s, not 4500. I like the 5100 better because they are silver zinc plated and look very nice in my wheel well compared to the yellow and blue 4600’s.
I had a discussion on the TC forum a while back about the difference since everyone seems to think you need a lifted truck for 5100’s. I ended up contacting Bilstein directly. They said order the 5100’s rated for 0-2” lift for non lifted trucks and they will work fine, and they do on 2 different trucks now. They also said they are the same inside.
