12″ DeeMaxx Disc Rotor | Ventilated

12″ DeeMaxx Disc Rotors are known for their ability to provide superior heat dissipation. By having ventilation gaps, air can better circulate in your discs which helps keep caliper brakes cooler.

DeeMaxx is known for their great quality in American boat trailer rotors. With a rotor thickness of 22mm, these brake hubs will suit both DeeMaxx and Kodiak hydraulic caliper brakes.

Each disc is supplied dacromet coated, as it provides great rust resistance which is especially important for boat trailers exposed to salt water.
