Cometic Bottom End Gasket Kit w/o Crank Seals Fits 04-08 Yamaha YFZ450

• Type: Gasket Kit

The Cometic Bottom End Gasket Kit is designed for rebuilding the lower end of 2-stroke and 4-stroke ATV and UTV engines. Each kit includes essential components such as oil seals, O-rings, drain plug washers, and water pump cover gaskets, tailored to the specific application. Materials used in the gaskets, including spring steel or graphite, are selected for durability and optimal performance under high horsepower, cylinder pressures, and extreme temperatures. Spring steel gaskets feature a stainless steel shim design with a silicone coating, while graphite gaskets are resistant to fuels, coolants, and oils. The kit meets the requirements for lower-end rebuilds, though a base gasket is not included. Designed for precision and reliability, it eliminates the need for additional sealants and ensures maximum engine efficiency and performance.
