Though BrakeTurbines work in almost 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, including the brand new 3899 from Gunite, just click on the drum itself.   

BrakeTurbines and certified and optimized drums are sold separately.  Contact the manufacturer for a retailer.
