These pistons are forged from 2618 billet bar stock and heat-treated to a T61 condition for exceptional strength and durability under extreme stress. Featuring an X-beam forging design, they offer superior rigidity compared to standard pistons.\n\nThe pistons boast a low-silicon content (less than one percent) to maintain their shape under high pressure and RPM, preventing skirt shrinking. They include CNC-turned skirts, oversized valve pockets with radius reliefs, forced pin oilers, accumulator grooves, double Spirolox retainers, and lock removal indents. Lightweight, heat-treated wrist pins are also supplied. These pistons are sold as a set of 8 and are designed for Chevy Big Block engines with a 4.600 in. bore.","brand":"Howards Cams","offers":[{"title":"Default Title","offer_id":53742529544504,"sku":"856027638","price":908.69,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/858356352.jpg?v=1793904251","url":"https:\/\/store.motormia.co\/products\/howards-cams-promax-x-beam-piston-set-4-600-bore","provider":"MOTORMIA","version":"1.0","type":"link"}
