Crafted from high-quality alloy cast in a permanent steel mold, this piston provides a lightweight yet durable solution designed to optimize engine performance. Its 3-1\/2 inch diameter and innovative construction enable more power output, quieter operation, improved fuel efficiency, and longer-lasting performance compared to traditional pistons. The alloy's low heat transfer characteristics help keep the piston skirts cool, minimizing expansion and promoting consistent operation under demanding conditions. The set includes a Hastings moly ring set, ensuring a reliable seal and enhanced longevity. Designed for use with a 3.812-inch stroke and a dish head, this piston set is specifically engineered to fit Harley models from 1986 to 1995, offering a straightforward upgrade for those seeking increased engine capacity without overboring the cylinders. It is important to note that 2009-UP XL 883 cylinders cannot be bored to 1200cc, and those applications will require separate purchase of 1200cc cylinders for compatibility. Proper break-in is essential; it is recommended to run the engine at moderate speeds for at least 500 miles, avoiding excessive running in lower gears to ensure optimal piston and ring seating. For installation, consult the provided instructions available at VTwin MFG. This piston set is assembled and shipped from the USA, ensuring quality and reliability. Accessory items such as the Ring-O-Matic Ring Compressor Kit, Connecting Rod Clamping Tool, and Piston Ring Grinder are recommended for an efficient installation process.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eMaterial: Alloy cast in a permanent steel mold for lightweight durability\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eDesign: 3-1\/2 inch diameter with low heat transfer alloy to keep skirts cool\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eIncludes: Hastings moly ring set for a reliable seal\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eCompatibility: Fits Harley Davidson XL models from 1986 to 1995, with specific considerations for 2009-UP models\u003c\/li\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003cli\u003eInstallation: Comes with detailed instructions for proper fitting and break-in procedures\u003c\/li\u003e\u003c\/ul\u003e\n\u003cbr\u003e\nFitment:\u003cbr\u003e\nHarley Davidson XL 1986\u003cbr\u003e\nHarley Davidson XL 1987\u003cbr\u003e\nHarley Davidson XL 1988\u003cbr\u003e\nHarley Davidson XL 1989\u003cbr\u003e\nHarley Davidson XL 1990\u003cbr\u003e\nHarley Davidson XL 1991\u003cbr\u003e\nHarley Davidson XL 1992\u003cbr\u003e\nHarley Davidson XL 1993\u003cbr\u003e\nHarley Davidson XL 1994\u003cbr\u003e\nHarley Davidson XL 1995\u003cbr\u003e\nHarley Davidson XL 1996\u003cbr\u003e\nHarley Davidson XL 1997\u003cbr\u003e\nHarley Davidson XL 1998\u003cbr\u003e\nHarley Davidson XL 1999\u003cbr\u003e\nHarley Davidson XL 2000\u003cbr\u003e\nHarley Davidson XL 2001\u003cbr\u003e\nHarley Davidson XL 2002\u003cbr\u003e\nHarley Davidson XL 2003\u003cbr\u003e\nHarley Davidson XL 2004\u003cbr\u003e\nHarley Davidson XL 2005\u003cbr\u003e\nHarley Davidson XL 2006\u003cbr\u003e\nHarley Davidson XL 2007\u003cbr\u003e\nHarley Davidson XL 2008\u003cbr\u003e\nHarley Davidson XL 2009\u003cbr\u003e\nHarley Davidson XL 2010\u003cbr\u003e\nHarley Davidson XL 2011\u003cbr\u003e\nHarley Davidson XL 2012\u003cbr\u003e\nHarley Davidson XL 2013\u003cbr\u003e\nHarley Davidson XL 2014\u003cbr\u003e\nHarley Davidson XL 2015\u003cbr\u003e\nHarley Davidson XL 2016\u003cbr\u003e\nHarley Davidson XL 2017\u003cbr\u003e\nHarley Davidson XL 2018\u003cbr\u003e\nHarley Davidson XL 2019\u003cbr\u003e\nHarley Davidson XL 2020\u003cbr\u003e\nHarley Davidson XL 2021\u003cbr\u003e\nHarley Davidson XL 2022\u003cbr\u003e\nHarley Davidson XL 2023\u003cbr\u003e\nHarley Davidson XL 2024\u003cbr\u003e\nHarley Davidson XL 2025\u003cbr\u003e\nHarley Davidson XL 2026\u003c\/div\u003e","brand":"Keith Black","offers":[{"title":"Default Title","offer_id":44653133299754,"sku":"11-2231","price":213.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/11-2231.jpg?v=1785886573","url":"https:\/\/atticusgoods.com\/products\/keith-black-883cc-conversion-piston-set-020-oversize-for-harley-davidson-xl-models","provider":"Atticus Goods","version":"1.0","type":"link"}
