For anyone interested in Bilstein's take on who should use which shock (it's question #4
here). Posting b/c this info seems to be known/accepted by some members and debated by others who believe the 5100 is somehow superior.
==
Our B6 4600 shock is for stock height vehicles while the B8 5100 are for lifted/leveled applications. If your truck is at stock ride height you would want to use our B6 4600 shock. If you have lift components installed on your truck and need a longer shock then you would want to use the B8 5100’s.
Both shocks are equally as durable and neither is better than the other.
