Start rolling and get your hands on a pair of the Ace AF1 Hollow Truck Polished. The all-new ACE AF1 features game-changing performance without deviating from our original ACE geometry with hollow axles and kingpins. The AF1 is carefully manufactured using our proprietary casting process. Years in development, the AF1 has a 70% increase in the aluminum's structural integrity, making it the strongest cast truck on the market. We updated the sizing on the 44 thru 77 models for a better fit across multiple board widths. Specifically manufactured for precision turning, easy flow and smooth grinding.
