Benefits include increased heat transfer, reduced friction and helping to eliminate cold seizures. Machined Smooth Heads - Reflects combustion heat and reduces carbon buildup, protecting the top of the piston. Some tests have shown this feature can increase horsepower and fuel economy by up to 6%. Anodized Domes - Increases heat resistance and durability; pistons with anodized domes are 75% stronger than non-anodized pistons. Hypereutectic Casting Process - Provides higher silicon content for reduced expansion rates and additional wear resistance; it also has an ability to withstand higher cylinder temperatures.\u003cbr\u003e\u003cbr\u003eVehicle Fitment:\u003cbr\u003e\u003cbr\u003e2017-2019 Polaris ACE 150\u003cbr\u003e 2018-2020 Polaris Ranger 150 EFI","brand":"Namura Technologies","offers":[{"title":"Default Title","offer_id":44181626388602,"sku":"8428745","price":39.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0004\/3312\/7455\/files\/ac1d2a000f5541e78370cc9b0157abe9.jpg?v=1784903441","url":"https:\/\/www.powersportsuperstore.com\/products\/namura-technologies-na-50100-2-piston-kit-0-50-oversize-to-57-88mm","provider":"Powersport Superstore","version":"1.0","type":"link"}
