I have a 2009 GMC Sierra 1500 with a 6-inch lift kit from Rough Country, and the N3 rear shocks that came with Rough Country kit were far too bouncy for my taste. Purchasing these shocks from Bilstein was 100% worth it. My Sierra no longer has excessive bouncing in the rear, and the installation was a breeze. I'm NEVER going to any other brand when it comes to shocks here on out.
