SPI 09-710061 Top End Gasket Set for Snowmobile Engine Rebuild Gaskets & Seals

The SPI 09-710061 Top End Gasket Set provides a comprehensive solution for snowmobile cylinder rebuilds, including high-performance reed and base gaskets. This complete gasket kit is engineered to OE specifications, ensuring perfect fitment without trimming or modification.

Key Features:

• Manufactured to OE specifications for precise fitment and reliability
• Materials selected specifically for temperature, oil, fuel, and coolant resistance
• Tested using ASTM standards to meet or exceed OE performance
• AF gasket material constructed from non-asbestos nitrile butadiene bonded cellulose fibers
• Maintains tensile strength and torque retention at temperatures exceeding 300°F
• Multi-layer steel (MLS) head gaskets feature stainless steel construction for corrosion resistance
• Fluoroelastomer rubber coating on MLS gaskets provides superior sealing on metallic surfaces
• NBR, Fluoroviton, and silicone seals selected based on temperature, abrasion, and chemical resistance
• Teflon coating applied to certain seals for extended performance life

What's Included:

• High-performance reed gaskets
• Base gaskets
• Top end seals and O-rings
• Note: Does not include intake/exhaust gaskets

SPI gaskets undergo rigorous quality control evaluation to ensure each component withstands the extreme heat and pressures found in snowmobile engines. The advanced MLS head gasket design resists shearing forces between cylinder head and cylinder surfaces while accommodating minor imperfections in mating surfaces during engine rebuilds.
