Bilstein 5100 or 4600?

[68bowtie]

I'm looking to install new rear shocks on my 2013 z71 crew cab. It's all stock. I like the look of the 5100 and less chance of rusting but I heard the 4600 ride smoother? Which would be a better choice?

both the 5100 and 4600 have the same valving no difference in ride the 5100 is for if you want to raise the height of the truck on the front
