I traded my Rancho 4000 for these per web recos. The stock Ranchos are too harsh for my liking, but I guess they look good. My Silverado 2017 was brand new, barely with a few thousand miles. I just bought this second set at 100M miles, many done in rally quality dirt roads. I'm still amazed they have lasted so long.Special mention must be made to the leveling feature of the front shocks. A simple and reliable mod that adds to the pickup's awesome looks. Just remember to order the 5100's with the leveling feature. I recommend the top notch for maximum height increase.
