Changed out the original shocks on my 2015 Chev dually. 103,000 on the originals. I installed 4600's all around. Highway ride is nothing short of spectacular! I think I should have done this a long time ago. My originals were toast.

I did this on my 2004.5 duramax at about 10,000 miles, even compared to almost brand new shocks the difference was amazing.
so... when we got our 2015.5 duramax first change I did. And the 04.5 still has the first set of bilsteins on it at 250K miles.
IMHO the factory shocks are not good for towing at all. not enough compression damping and way to quick on the rebound.
Bilsteins have much better compression damping and slower rebound for a much better ride.
