Cylinder Sleeve For 2-Stroke

Restore performance and extend the life of your 2-stroke engine with the LA Sleeve KA5180 cylinder sleeve. This quality replacement liner is designed to bring worn or damaged alloy-chrome plated, Nikasil, or electrofused cylinders back into service, helping you avoid replacing the entire cylinder. With precisely cut ports and a precision-ground outside diameter, it supports easier installation and better port alignment for a proper rebuild.

If your cylinder plating is worn, scored, or beyond repair, resleeving is a proven solution that can return compression and reliability—especially important on high-output 2-stroke engines.

Key features:

• ✅ Ports cut to precise dimensions and shapes for easier installation and port match-up
• ✅ Outside diameter centerless-ground for accurate fitment
• ✅ Quality replacement sleeve that renews older cylinders

Benefits of using it:

• 🔹 Cost-effective cylinder recovery when plating is damaged or worn
• 🔹 Improved rebuild consistency thanks to accurate OD and port machining
