Yamaha Motor Co., Ltd. 8K4-11601-30-00 Piston Ring Kit

The Yamaha 8K4-11601-30-00 Piston Ring Kit is a genuine Yamaha replacement component designed to seal the combustion chamber and control oil distribution in snowmobile piston and cylinder systems. This complete piston ring set (multiple rings per piston) fits Yamaha Enticer, ET400, ET410, SS440 and similar models, helping maintain compression and minimize blow-by during repair, maintenance, and engine rebuilds. The rings mount in the piston grooves within the cylinder and use hardened steel or cast iron alloy for durability to support stable engine operation. Common replacements include 8K4-11601-00-00, 8K4-11601-10-00, and 8K4-11601-20-00.
