Direct bolt on replacement for my original shocks that were really shot after 130,000 miles. Considered the OEM Bilsteins but these got such great reviews that it really swayed my decision. These are very expensive but it was worth every penny. Initially felt slightly stiff but either I'm getting used to them or they are loosening up slightly. These really restored my ride quality. I've hit some potholes hard that I couldn't dodge and these really do a wonderful job dampening. General highway driving I would say that the ride was firm but not harsh. Going into bends these help keep the truck level. Braking dive changed drastically for the better. Overall money well spent. Even the guys at the local garage had a good time making fun of them. "Hey look at the truck with the chrome bilsteins!" Although they are actually a brushed aluminum housing they do look good. Thanks Amazon!

I replaced the front shocks on my 2004 Avalanche with these Bilstein shocks. Super easy and better hardware that the previous shocks. So far ride is way better and they look cool.
