Pistons are proudly made in the USA from 2618 forgings and are available with 5cc solid domes, -4.6 cc flat top, and -25cc dish. Pistons feature .220 deep intake pockets, 1.2mm steel gas nitride ring, 1.2mm Napier second ring, 3.0mm oil ring and include .927 x 2.250 pins with a .180 wall standard.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003eNote on rod small end widths - These piston forgings have a minimum pin boss span of 1.060, this is because they also use a 2.250 long wrist pin, to this gives the wrist pin .595 of engagement In the pin bore. Many aftermarket rods including BTR's 6.125 LS rod set (BTRROD6125H1-8) have a small end width of 1.060 or more and will need to have the small end narrowed by a respectable machine shop by .080-.100\" for proper fitment. Carrillo \u0026amp; Bullet rods use a .900-1.000 wide small end, so there is no need for additional small end clearancing.\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003ctable class=\"data table additional-attributes\" id=\"product-attribute-specs-table\"\u003e  \u003ctbody\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eBTR SKU\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"BTR SKU\"\u003eCPBLSR1200-STD\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eLength\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Length\"\u003e20.000000\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eWidth\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Width\"\u003e8.000000\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eHeight\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Height\"\u003e3.000000\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eWeight\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Weight\"\u003e15.000000\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eBrand\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Brand\"\u003eCP\/Carrillo\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003ePart Type\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Part Type\"\u003ePistons\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003ePiston Style\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Piston Style\"\u003eDome\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003ePiston Volume\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Piston Volume\"\u003e5.0cc\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003ePiston Bore Size\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Piston Bore Size\"\u003e4.125\"\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003ePiston Stroke\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Piston Stroke\"\u003e4.000\"\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003ePiston Pin Size\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Piston Pin Size\"\u003e.927\"\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eRod Length\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Rod Length\"\u003e6.125\"\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eEngine Type\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Engine Type\"\u003eLS7\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e","brand":"CP Pistons","offers":[{"title":"Default Title","offer_id":62809064046751,"sku":"CPBLSR1200-STD","price":1219.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0424\/7571\/6767\/files\/blsr1200-std.jpg?v=1780752477","url":"https:\/\/streetdrivenperformance.com\/products\/cp-bullet-series-ls7-piston-set-4-125-bore-4-000-stroke-6-125-rod-5cc-dome-blsr1200-std-cpblsr1200-std","provider":"Street Driven Performance","version":"1.0","type":"link"}
