In Colorado and Nebraska there are certain stretches of concrete interstate that create a rocking/vibration motion in my 03 Sierra Denali when traveling between 70-80 mph, will new shocks help? If yes, is there any consensus on the best shock, bilstein, rancho, edelbrock? Thanks

I use the Rancho 9000's which are adjustable and have had good luck with those...the ride is alot smoother than the factory auto ride shocks that came with it. Hope that helps..

Thanks for the suggestion. Those shocks are certainly on the top of my list for consideration. Do you have the part numbers? Thanks
