{"product_id":"mid-sleeve-3-400-bore","title":"MID Sleeve 3.400\" Bore","description":"The Darton MID™ Sleeve Kit (part #700-130) is engineered for Ford EcoBoost engines, offering a robust solution for performance builds. It addresses the inherent cylinder stability weakness found in many production cast iron and aluminum blocks, particularly in high horsepower, high boost, or larger bore applications where \"cast in sleeves\" may not suffice. This patented Modular Integrated Deck (MID) design uses nested sleeve flanges to create a solid deck, reinforcing the upper deck area and allowing for individual sleeve replacement.\n\nDarton's MID sleeves enhance engine performance and longevity through several key benefits. The sleeves are constructed from durable Darton ductile iron with a tensile strength of 130,000 psi, capable of handling increased horsepower potential while offering superior oil and compression control, along with enhanced cylinder sealing and ring wear. The product details include a 3.400\" bore, 3.950\" OD, 0.275\" wall thickness, 5.750\" length, 0.4\" flange thickness, and a 4.840\" flange diameter, suitable for bore sizes from 87mm to 90mm MAX.\n\nSpecific fitment for the Darton 700-130 sleeve includes the Ford Mustang 2.3L EcoBoost from 2015-2022. The sleeves come with a phosphate coating for optimal corrosion and rust resistance, which also adds a protective barrier for the o-rings, extending their lifespan. This advanced sleeve design is suitable for both street and strip applications.","brand":"Darton","offers":[{"title":"Default Title","offer_id":52687607988536,"sku":"700-130","price":768.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662653465.webp?v=1784885575","url":"https:\/\/store.motormia.co\/products\/mid-sleeve-3-400-bore","provider":"MOTORMIA","version":"1.0","type":"link"}
