ACT Xtreme Race Discs are available in 4 or 6-puck hub designs that are highly durable and resistant to heat. ACT 4-puck Xtreme Discs engage harsher, shift faster, and are well suited for the smaller disc sizes from smaller engines.
Available in both Sprung and Solid Hubs, ACT has the Race Disc right for you.
