With the continued success of our Turbomac design, we thought it was time that the off-road community deserved something strong, light and unique. So we got together with Ken Block and decided that the Turbomac HD needed to become a reality. After over a year of rigorous testing on his Ford Raptor, Ken put his new signature Turbomac HD to the test and gave it the green light. Now, we are very pleased to be able to offer it as part of our Cast Monoblock wheel lineup.
