My 2010 CC SE 4X4 since new suffers from suspension topping out front and rear especially over speed bumps. I have read many forums which offer fixes from replacing the front springs with shorter springs(don't want to lower the front end)(also doesn't address the topping out in the rear). Also Bilstein shocks are a known fix. Here is my point, this should be fixed under warranty as the truck has 6000 miles on it. Has anyone tried the RANCHO SHOCKS from the PRO-4X? Does the PRO-4X have this issue?
