Though BrakeTurbines work in any 16.5" drum, they work best in BT certified or optimized drums.  These drums are designed from the ground up to take full advantage of BrakeTurbines patented cooling, cleaning power.  To see more about any of the drums above just click on the picture of the drum to take you to the appropriate page.   

BrakeTurbines and certified and optimized brake drums are sold separately.  Contact your drum manufacturer for a retailer in your market area.
