{"product_id":"bullet-series-forged-piston-set-4-125-bore","title":"Bullet Series Forged Piston Set, 4.125\" Bore","description":"The CP Carrillo Bullet Series piston set is engineered for GM LS engines utilizing 15° cylinder heads, including the 4.8, 5.3, 5.7, 6.0, and 6.2L variants. These pistons boast a 4.125\" bore and a 3.622\" stroke, with a 1.300\" compression height designed to work with 6.125\" connecting rods.\n\nConstructed from high-strength 2618 forgings, these pistons are proudly made in the USA. They feature a flat top design with a -2.7cc volume, resulting in a 10.2:1 compression ratio. The design includes special skirt treatments to minimize piston noise during operation. The set comes complete with a robust ring package, featuring a 1.5mm steel gas nitride top ring, a 1.5mm Napier second ring, and a 3.0mm oil ring. Standard .927 x 2.250\" wrist pins with a .180 wall thickness are also included.\n\nThese pistons are built to withstand demanding conditions and are suitable for high-performance applications involving nitrous oxide, superchargers, or turbochargers. Specifically, piston forgings have a minimum pin boss span of 1.060\". If using aftermarket rods with a small end width of 1.060\" or more, the small end may need to be narrowed by approximately .080\"-.100\" by a machine shop to ensure proper fitment with the 2.250\" long wrist pin.","brand":"CP","offers":[{"title":"Default Title","offer_id":52687476687160,"sku":"CPC-BLS1012-125-8","price":955.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661670450.jpg?v=1784884616","url":"https:\/\/store.motormia.co\/products\/bullet-series-forged-piston-set-4-125-bore","provider":"MOTORMIA","version":"1.0","type":"link"}
