Crafted from high-density chrome-moly alloy, this sleeve provides a durable, wear-resistant surface that often exceeds the longevity of original equipment. The outside diameter is precision centerless ground to ensure a perfect fit into your cylinder casting, while the ports are pre-cut to exact factory dimensions for seamless alignment and maximum airflow. Designed for a standard 54.00mm bore, this sleeve offers a cost-effective alternative to expensive cylinder replacements, allowing you to bore and hone for a custom, tight-clearance fit with your new piston.
