{"product_id":"4-125-bore-3cc-flat-top-piston-set","title":"4.125\" Bore 3cc Flat-Top Piston Set","description":"The BTR CP Piston and Ring Set is a robust solution for Gen III Hemi and LS\/LT engine builders seeking a durable, boost-ready piston kit. The pistons are forged from 2618 alloy, ensuring strength and durability for demanding applications.\n\nKey features include dual forced pin oilers, accumulator grooves, and forged side relief for enhanced performance and longevity. The set is balanced to within +\/- 1 gram and includes heavy-wall .230-inch Chromoly wrist pins with wire locks. FEA-designed forgings and tight tolerances contribute to its precision engineering.\n\nFor improved ring seal, the pistons incorporate lateral gas ports. The included Premium Total Seal AP ring set features a 1.2mm x 1.2mm x 3.0mm configuration. This pack consists of 440B Stainless Steel top rings with a C33 Face Coating, Taper Hook Groove Napier second rings, and a 3-piece soft-nitrided rail flex vent oil ring, specifically designed for severe duty applications like nitrous, blowers, and turbo engines.\n\nIt is important to note that these piston forgings have a minimum pin boss span of 1.060 inches, accommodating a 2.250-inch long wrist pin. Many aftermarket rods, including BTR's 6.125 LS rod set, have a small end width of 1.060 inches or more and will require narrowing by a machine shop by .080-.100 inches for proper fitment. Carrillo and Bullet rods with a .900-1.000 inch wide small end will not require additional clearancing.","brand":"Brian Tooley Racing","offers":[{"title":"Default Title","offer_id":52687475212600,"sku":"BTRCP-LS41251300-FT-8","price":999.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661670435.jpg?v=1784884601","url":"https:\/\/store.motormia.co\/products\/4-125-bore-3cc-flat-top-piston-set","provider":"MOTORMIA","version":"1.0","type":"link"}
