Replace or upgrade the bushings on your Ace AF1 or Classic trucks with a set of Ace hard bushings! Constructed with 94a durometer urethane, these bushings are great for skaters who prefer tighter trucks. Increased durometer bushings provide less wheel bite, better shock absorption, and stability. Ace responsiveness provides the optimal rebound in these bushings. If you regularly skate gaps or stairs, you'll want to throw a set of these in your trucks. This kit includes enough bushings and washers to service both trucks.
