I have the Downey 3" springs, they flex alright, the ride is really good, BUT in my opinion they are too soft. The rear sags when I put ANYTHING in the bed. I'm satisfied, but if I were to do it over they would not be my first choice. BTW, Had them for about 1.5 years now, not any hard rockcrawling abuse.
