{"product_id":"pro-h-connecting-rod-set-with-carr-bolts","title":"PRO-H Connecting Rod Set with CARR Bolts","description":"The CP-Carillo PRO-H Connecting Rod Set provides a lightweight yet high-strength upgrade for the connecting rods in BMW N55 and S55 6-cylinder turbocharged engines. These rods are manufactured in the USA from proprietary steel forgings, a material known as Carrilloy, which is enriched with chrome, nickel, molybdenum, and vanadium for enhanced durability. Each connecting rod undergoes heat treatment and shot peening processes to further increase its strength and resilience under demanding conditions.\n\nThis set features upgraded CARR connecting rod bolts and is designed with specific dimensions: a center-to-center length of 144.3mm, a pin width of 20.88mm, a big width of 20.88mm, a big bore of 53.62mm, and a pin bore of 22.00mm.\n\nImportant fitment notes include that this set is not for use with original BMW pistons. Additionally, installation requires a slight modification to the bottom of one side of each cylinder sleeve to resolve a minor clearance issue caused by the offset crankshaft. These connecting rods are suitable for models such as the F87 M2, F80 M3, F82\/F83 M4, E82 135i\/135is, F22 M235i, F30 335i, F32 435i, and F10 535i.","brand":"Carrillo","offers":[{"title":"Default Title","offer_id":52687350169912,"sku":"SCR9104","price":368.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661175544.jpg?v=1784883102","url":"https:\/\/store.motormia.co\/products\/pro-h-connecting-rod-set-with-carr-bolts","provider":"MOTORMIA","version":"1.0","type":"link"}
