Just going to put this out there! The ZR2 is just the trim level that we all chose. It happens to be a very expensive truck but obviously not immune to problems. Mechanically it is the same Silverado as a Trail Boss, an LTZ and any other with a 6.2 and 10 speed. Aside from the lockers and the shocks, it's a Silverado with a 6.2 which GM made and continues to make tens of thousands of. I realize that I'm on a ZR2 forum and that's what I'm going to hear the griping about, but some of these gripes are so friggin petty and stupid, I'd be embarrassed to post them. Would I get pissed off if my engine grenades?, yes, but the bashing of this truck on this forum is unbelievable. I absolutely love this truck and wish I lived in an area where I can use more of its potential, but even just driving this thing to work is a pleasure. The ride blows away my last LTZ and the power and sound with the Borla exhaust and the 6.2 is really a joy to drive. It's a beautiful pickup and i get tons of compliments. Most of us will be ok and hopefully won't have to use our warranty, but we have it just in case. Go to a Tahoe forum and you can hear them complain about the same "dreaded" lifter issues. The problems are not exclusive to the ZR2. In fact, the exclusive parts that make it a ZR2 work great. I rarely hear of the lockers failing or the shocks leaking... so if we're going to own a Silverado I still think we own the best of the best! If you hate GM, you bought the wrong truck, go to Ram or Ford and deal with their issues because they have some good ones too!
