Ductile Iron Cylinder Sleeve Set

The Darton MID (Modular Integrated Deck) Cylinder Sleeve Kit, part number 800-550, is engineered for enthusiasts serious about tuning their Volvo 5-cylinder turbo engines for maximum performance. Production cast aluminum blocks often have inherent weaknesses in cylinder stability, particularly in the upper deck area, which can limit high horsepower and boost potential. These performance cylinder sleeves address this by creating a reinforced, solid deck structure. Manufactured from high-strength ductile iron with a tensile strength of 130,000 PSI, these sleeves offer the durability of cast iron within an aluminum block. Key benefits include improved integral block strength, increased potential for horsepower and torque output, and the ability to handle higher boost pressures. They also contribute to superior cylinder sealing and reduced ring wear. The sleeves are designed to accommodate a bore range of 83MM to 85MM, with a standard bore size of 3.260 inches. The specific dimensions include an outer diameter of 3.750 inches, a wall thickness of 0.245 inches, a length of 5.400 inches, a flange thickness of 0.400 inches, and a flange diameter of 4.470 inches. This kit includes five sleeves, as the price reflects. This specific kit is designed for a wide range of Volvo 5-cylinder turbo engines, spanning model years from 1994 to 2007. Compatible models include the Volvo 850, C70, S60, S70, S80, V70, XC70, and XC90, across various trims like T-5R, R, GLT, T5, and 2.4T, with engine displacements including 2.3L and 2.4L. The fitment list is extensive, covering numerous drivetrain and gearbox configurations for both FWD and AWD vehicles.
