Mike Barabash 1 hr Hi Everybody! I have a question about my lifted 07 Avalanche It has a 7.5 Rough Country lift.. My problem is that the rear of the truck feels real loose/Sway and like it wants to turn before the front of the truck does. It's scary driving on the parkway. the R/C lift i went with i added R/C front struts and Rancho rear shocks i also added 2 inch wheel spacers for the rear and a helwig rear adjustable rear sway bar. I have called R/C twice and they have no clue of what it is. i am almost at the point on bringing it back down to stock ride height.. I love the way the Avalanche looks but feels very dangerous at highway speeds. Any help would be Appreciated..
