This component is specifically engineered for high mileage street applications and is recommended for dual spring setups that accumulate over 7000 miles annually, or as a cost-effective alternative.\n\nKey specifications include a 5.5mm stem diameter, a 1.047\" outer diameter, and step measurements of 0.866\" for Step 1 and 0.605\" for Step 2. The installation height is stock, ensuring compatibility with existing valvetrain setups. The retainer weighs 13.2 grams.\n\nThis retainer is intended for use with Honda\/Acura B18C\/B16A, H22, K Series, and F Series engines. When utilizing late model cylinder heads (after 2004), it may be necessary to purchase BC2940 keepers to accommodate these retainers.","brand":"Brian Crower","offers":[{"title":"Default Title","offer_id":52687289090360,"sku":"BRCBC2011","price":5.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661666399.webp?v=1784882289","url":"https:\/\/store.motormia.co\/products\/bc2011-1-steel-retainer","provider":"MOTORMIA","version":"1.0","type":"link"}
