Got cut short on the end, but all I have to say is Wow, went from hitting a crack(earthquake) in the road and feeling massive reverberations(after shocks) of that one small bump to hardly feeling any after shocks. Still has some reverberation over large and I Mean Large cracks, but the average driving down the road is Greatly Improved! Google 2005 duramax frame beaming to read up and get the part numbers and procedures to replace your rear cab bushing with the updated bushings today, makes a world of difference for me on my crew cab.
