Once again, ACE is proud to introduce the most technical and performance driven trucks to date with a revolutionary inverted kingpin system. Engineered for maximum durability, unrivalled performance, precision turning and guaranteed lowest grind clearance of any kingpin on the market. At the heart of the design is Click Lock Pro patent pending technology providing a more stable anchor point for the kingpin. An all new special hollowed axle system and domed-out baseplate make it the strongest and lightest truck we've ever created.
