Great Upgrade to New Truck
I have a 2016 Silverado 2500 HD with Z71. Ride was really firm I felt because of the factory shocks so my research brought me to these. I installed them and experimented with settings and ended up at setting 4 up front and 3 in rears. I may increase to 5 and 4 in the Summer but it is nice knowing I have a lot more firmness available for towing if needed. These shocks improved the ride dramatically and I highly recommend them!
