High-compression or forced-induction builds require forged pistons.\u003c\/p\u003e\n\u003ch3\u003eWhy hypereutectic instead of forged?\u003c\/h3\u003e\n\u003cp\u003eHypereutectic alloy offers low thermal expansion, tight ring seal, quieter operation, and reduced wear in air-cooled engines. Forged pistons are needed only for aggressive compression or boost.\u003c\/p\u003e\n\u003ch3\u003eIs this a complete piston kit or just the piston?\u003c\/h3\u003e\n\u003cp\u003eThis is the individual piston (.010 oversized). Check with your engine builder to confirm you need all matching components — rings, pins, and clips may be ordered separately.\u003c\/p\u003e","brand":"Kb Pistons","offers":[{"title":"Default Title","offer_id":53035461279855,"sku":"824-01014","price":254.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/6734\/6543\/files\/output_8cfeade2-97f7-45a2-b168-2546b62c19bd.png?v=1779561830","url":"https:\/\/vtwinbikers.com\/products\/kb-pistons-hypereutectic-cast-piston-pistons-evo-80ci-10-5-1-010-824-01014","provider":"Vtwinbikers","version":"1.0","type":"link"}
