Repl Cyl Sleeve Honda H22 3.415 Bore 3.650 OD

The Repl Cyl Sleeve Honda H22 3.415 Bore 3.650 OD by Darton Sleeves is a precision cylinder liner engineered for high-performance H22 engine builds. This replacement sleeve serves builders and mechanics who are pushing beyond factory bore limits, whether for a full engine overbore or restoring a previously damaged cylinder. The H22 platform—favored in Accord, Prelude, and swapped applications—demands quality liners when displacement and compression are the goals.

Darton cylinder sleeves are centrifugally cast ductile iron, designed to withstand elevated combustion pressures and thermal cycling without distortion or wear. The 3.415-inch bore specification allows proper piston-to-bore clearance while the 3.650-inch outside diameter ensures a secure interference fit within the block when honed and installed correctly. This particular sleeve maintains dimensional stability under boost, high RPM, and extended load—critical when forced induction or nitrous oxide enters the equation.

Installation requires precision honing, proper block preparation, and a press to set the liner at exact depth—tasks best handled by an experienced machine shop familiar with H22 architecture. The casting process and hard-anodized finish resist corrosion and scoring from ring contact, extending cylinder wall life across thousands of dyno pulls and street miles. This product is ideal for serious street and competition builds, ensuring reliability and performance.
