Let me guess, you have the stock GM Rancho shocks in your Silverado 1500. The ones that make you nauseous from the yo-yoing that happens when you run over a pebble, put your heart in your stomach when the rear end bounces around on the highway because you hit 1/2 inch depression, or when you hit the skid plates going 1.4 mph over speed bumps. Guess what, Eibach Pro Shocks fixes all that and handle great as well. Just buy em.
