Billet Aluminum ACR Plugs for Twin Cams - only $19.95 each


HAMMER PERFORMANCE Billet Aluminum ACR plugs for Harley Davidson Twin Cam Automatic Compression Releases


CNC machined from 6061T6 billet aluminum, these plugs provide an effective means for blocking off the automatic compression release holes found in many late model Twin Cam heads. Because they're aluminum, they can welded and machined, the ideal solution to eliminate the fuel trap hot spot caused by the ACR hole. Also excellent for machining angled squish bands. Sold each
