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.

I installed these on my 2006 Tahoe LT 4WD after I installed lift torsion keys and took it up around 1 3/4" inches in the front to level it out. I can't stand the jacked up back end look. No more diving in the front at braking and they seem to soak up the bumps much better than the extended factory shocks. To be honest though, by cranking up your torsion keys the ride will still be stiffer than the factory ride even with these shocks. You end up felling more of the smaller cracks and imperfections not so much the big pot holes though, these shocks take care of that no problem. I installed a pair on the front in the driveway in about an hour. Don't go with the goofy extenders on your factory worn out shocks. These are worth the money and will make you smile after the first ride down the street. I drive 98% on road a year just to let you know. Buy these and play it safe and be happy. You can tell the quality of these shocks right away. You wont find a cheaper price online either.
