Problem Solver Darton Sleeves K20c 86mm Upgraded Model [2zly481I]

Darton Sleeves K20c 86mm

The Darton Sleeves K20c 86mm are designed to address the inherent weaknesses in many production cast iron and aluminum blocks, providing a robust solution for high-performance engines. These sleeves are crafted with a unique design that, when siamesed and nested, create a solid deck of sleeve flanges, reinforcing the upper deck area and ensuring in-field replacement with Darton's Modular Integrated Deck (MID) technology. This innovative design not only enhances the structural integrity of the engine but also optimizes cooling efficiency.

Technical Advantages

The Darton Sleeves K20c 86mm are engineered to manage and enhance water flow from the block to the head, promoting stability in cooling. This is achieved through "swirl coolant technology," which starts with specific engineering models of cylinder head and combustion chamber designs. Each engine and cylinder design has a unique engineering model to promote increased water flow in the upper sleeve area subjected to the most heat. The benefits of this technology include improved cooling, superior cylinder sealing, and ring wear, all of which contribute to increased horsepower output potential and superior oil and compression control.

Applications and Benefits

The Darton Pro-Sleeve Kit is available for a wide range of 4, 6, and 8-cylinder import and domestic engines, offering maximum bore sizes and boost potential. This kit is perfect for both street and strip applications and can be installed by your local machine shop. The benefits of using the Darton Sleeves K20c 86mm include improved block integral strength, "wet sleeve" replaceability, and a full installation manual with every kit sale. With Darton's ductile iron sleeves, which boast a tensile strength of 130,000 psi, you can be confident in the kit's ability to handle high boost and horsepower scenarios. The Darton Sleeves K20c 86mm are the ultimate choice for those seeking to maximize the performance and longevity of their engines.
