Dry Sleeve Set with Flange

The Darton 300-010 is a set of four dry sleeves designed for Honda and Acura engines, specifically replacing the factory cylinder liners with a significantly stronger and more durable component. The "Dry Sleeve" design is characterized by the absence of water or coolant passages through the top flange. This solid construction results in a more rigid structure, which is crucial for preventing warping and sleeve expansion under extreme conditions. The sleeves are manufactured with precise dimensions: a 2.940-inch bore, 3.250-inch outer diameter, 0.155-inch wall thickness, 5.400-inch length, 0.375-inch flange thickness, and a 3.340-inch flange diameter. It is important to note that Darton sleeves require finishing and honing at a machine shop to precisely match the specifications of the pistons being used in the build. The purchase includes a full set of four engine sleeves. Buyers are advised to carefully select the correct sleeve option and consult with their engine builder if unsure about fitment or specifications before purchasing. The specific part number 300-010 is for the D16 engine variant with a flange.
