{"product_id":"ductile-iron-dry-cylinder-sleeves","title":"Ductile Iron Dry Cylinder Sleeves","description":"The Darton 300-033 is a set of Modular Integrated Deck (MID) dry sleeves engineered to replace factory cylinder liners in Subaru EG33 engines, offering enhanced durability and performance potential. Constructed from bulletproof Darton ductile iron with a tensile strength of 130,000-psi, these sleeves are designed to provide cast iron performance in an aluminum block.\n\nDarton's MID design addresses inherent block weakness by creating a solid deck of sleeve flanges, reinforcing the upper deck area and allowing for individual replacement. The sleeves are further enhanced with \"Swirl Coolant Technology™\" to manage and improve water flow for stable cooling, particularly in the upper sleeve area subjected to high heat. This technology, along with \"Register Fins™\", aids in dissipating heat, preventing detonation, and allowing for increased horsepower potential and high boost applications.\n\nTo combat corrosion and rust, common issues with standard wet sleeve designs, the Darton MID sleeves feature a phosphate coating. This microcrystalline structure offers superior corrosion and rust resistance, acting as a protective barrier for the o-rings and resisting abrasion from turbulent coolant flow. This feature makes the sleeves impervious to problems typically found in wet-sleeved blocks and contributes to superior cylinder sealing and ring wear.\n\nThe Darton 300-033 sleeve kit is designed for street or strip applications and supports bore sizes ranging from 97mm to 100mm, with an outside diameter of 4.201 inches, a wall thickness of 0.196 inches, and a length of 4.8 inches. The kit's benefits include improved block integral strength, enhanced cooling, superior oil and compression control, and high boost and horsepower potential.","brand":"Darton","offers":[{"title":"Default Title","offer_id":52664212128056,"sku":"300-033","price":712.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687387267.webp?v=1784335234","url":"https:\/\/store.motormia.co\/products\/ductile-iron-dry-cylinder-sleeves","provider":"MOTORMIA","version":"1.0","type":"link"}
