Each piston is constructed from 4032 high-silicone aluminum alloy, a material chosen for its combination of high strength and excellent wear resistance. The design includes two valve reliefs to accommodate performance valve train configurations.\n\nTechnical specifications for this set include a 4.03-inch bore, a 3.58-inch stroke, and a 1.667-inch compression height. The pistons utilize a 0.927-inch pin diameter and are configured with 1.5mm top and 1.5mm second ring grooves, along with a 3.0mm oil ring height. The crown volume is -5cc, which results in varying compression ratios depending on cylinder head volume: 11.3:1 at 60cc, 10.6:1 at 65cc, and 10.1:1 at 70cc.","brand":"Mopar","offers":[{"title":"Default Title","offer_id":52689281745208,"sku":"1000549","price":689.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687480784.jpg?v=1784904620","url":"https:\/\/store.motormia.co\/products\/forged-flat-top-piston-set-1","provider":"MOTORMIA","version":"1.0","type":"link"}
