Predator Revo shaft, 11.8mm with Uni-Loc joint. I am selling this because it didn't suit me. The 11.8mm is currently out of stock from the manufacturer, making it rare. Please purchase only if you understand that this will be shipped by an amateur. Please refrain from purchasing if you are sensitive to items stored at home. Thank you.
