Put this center support bearing on my 2006 Chevy C6500 and it made a night-and-day difference. No more rattling or vibration—just a smooth, steady ride. Installation was straight forward too.

Replaced the bearing on my 2005 GMC C5500 with this part and it fits perfect. Truck runs smooth again even with a full load. Definitely worth it for the price and quality.
