Crafted with a 4.065-inch bore and a 4.125-inch stroke, these pistons provide optimal power and efficiency. Each piston features a 6.125-inch connecting rod compatibility and a piston pin diameter of 0.927 inches, ensuring a precise fit for demanding engine applications. The set includes eight pistons, perfectly suited for rebuilds and performance upgrades in GM LS series engines. Constructed from high-quality materials, these pistons contribute to reliable engine operation and longevity. The Mahle pistons come with a compression ratio of approximately 11.1:1, delivering a balance of power and fuel efficiency. Their lightweight design, with each piston weighing around 7.2 ounces, helps reduce overall engine stress and enhances responsiveness. The pistons feature advanced coatings: phosphate treatment for corrosion resistance, Grafal coating to minimize friction, and a hard anodized top ring groove to improve wear resistance. These enhancements ensure longevity even under high-performance conditions. Please note that these pistons are not carb-legal and require acknowledgment of this status during installation. They are suitable for use in non-carbureted engines and are essential components for custom engine builds or performance upgrades. Proper installation and compliance with all relevant regulations are recommended to ensure optimal engine function and durability.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned for GM LS 427 cubic inch engines with 4.065-inch bore and 4.125-inch stroke\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSet includes eight pistons with a 6.125-inch connecting rod compatibility\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePiston pin diameter of 0.927 inches for precise fit and smooth operation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompression ratio of approximately 11.1:1 for balanced power and efficiency\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eConstructed from high-quality materials for durability and performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCoatings include phosphate for corrosion resistance, Grafal to reduce friction, and hard anodized top ring groove for wear resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLightweight design around 7.2 ounces per piston to improve engine responsiveness\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSuitable for non-carbureted engines; carb acknowledgment required\u003c\/li\u003e\u003c\/ul\u003e","brand":"Mahle","offers":[{"title":"Default Title","offer_id":46982656983239,"sku":"mhl930225265","price":962.97,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0665\/2277\/5751\/files\/3ca5314bdfcae5e6e1828e5c16d70b35_67c160a5-a6d0-48ea-89ee-76b0109ab1ae.jpg?v=1786497499","url":"https:\/\/mainstreeteshop.com\/products\/mahle-ms-piston-set-for-gm-ls-427ci-with-4-065-inch-bore-and-4-125-inch-stroke","provider":"MAIN STREET ESHOP","version":"1.0","type":"link"}
