Upgrade Your Performance with Moose Offroad Complete Gasket Kit with Oil Seals

A high-performance engine is only as good as its sealing, and even a minor vacuum leak or oil weep can lead to catastrophic failure on the track. The Moose Offroad 0934-6449 Complete Gasket Kit with Oil Seals is designed to solve the complexity of engine rebuilding by providing a 100% comprehensive solution for your Yamaha YZ85. At Moto-House MX, we know that cutting corners on a rebuild isn't an option for champions, which is why we provide this all-in-one Heavy Duty kit to ensure your motor remains airtight and oil-tight from the first heat to the final flag.

Engineered and Made in the USA, this kit features precision engineering that includes every gasket and oil seal required to refresh both the engine and transmission. Unlike basic sets, this version includes genuine OEM replacement oil seals to provide the ultimate mechanical efficiency and durability. Whether you are splitting the cases for a full crank service or just performing seasonal maintenance, these high-tech materials offer a perfect fit for the updated YPVS-equipped Yamaha 2-stroke, ensuring your machine maintains peak compression and reliable lubrication.
