{"product_id":"automatic-compression-release","title":"Automatic Compression Release","description":"By automatically reducing cylinder compression during the initial moments of startup, it lessens the load on your starter and battery, extending their lifespan. Once the engine achieves ignition and begins running, the ACR valves automatically close, restoring the necessary full compression for optimal engine operation.\n\nIt is compatible with all '07-later Twin Cam-equipped Harley-Davidson models. However, installation requires professional machining using the Screamin' Eagle® Automatic Compression Release Fixture Kit P\/N 94648-08, which must be purchased separately. Additionally, a model-specific ACR Wiring Harness is also required and must be purchased separately.\n\nKey fitment details include compatibility with '07-'17 Twin Cam-equipped models, and it can be used with either Original Equipment or Screamin' Eagle® Cylinder Heads. It is important to note that this component does not fit with Twin-Cooled engines.","brand":"Screamin' Eagle","offers":[{"title":"Default Title","offer_id":52663620501816,"sku":"28861-07A","price":45.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687676700.jpg?v=1784328511","url":"https:\/\/store.motormia.co\/products\/automatic-compression-release","provider":"MOTORMIA","version":"1.0","type":"link"}
