Ok, I'm getting confused as to which Bilstein shocks I should get. And after doing a bit of search, I noticed people recommend the 5100 20% stiff in the front and OE in the back. Why is that? I understand the 20% in front is to help carry the extra weight of trucks with winch bumpers, but why not put 20% in the back as well so that when you go haul those bags of rock salt from Home Deopt, your truck don't sag.

Does the 20% stiff in the back make the ride too bumpy, loose, and harsh when there's no cargo in the back?

And how much of a difference are the Bilstein OE from the 20% stiff?

Thanks
