The Briggs & Stratton Cylinder Head Gasket 271866S is a genuine OEM replacement cylinder head gasket engineered to maintain the integrity of your Briggs & Stratton engine’s top-end seal. Designed to fit a wide variety of small petrol engines in the 22, 25 and 28 series family, this gasket creates a dependable seal between the cylinder head and engine block to help preserve compression and prevent leakage of combustion gases, oil and other fluids.
The cylinder head gasket is a critical part of your engine’s combustion chamber sealing system. Installed between the cylinder head and crankcase, it withstands high heat and pressure while ensuring proper compression and preventing internal leaks that can lead to poor performance or engine damage. This genuine gasket replaces several older part numbers including 270796, 271075 and 271866, ensuring compatibility across many Briggs & Stratton horizontal and vertical shaft engines.
Key Features:
OEM-Quality Seal: Genuine Briggs & Stratton part manufactured to factory specifications for reliable long-term performance.
High-Temperature Resistance: Robust composite construction resists combustion heat and pressure to help prevent blow-by and leaks.
Precision Fit: Engineered for a precise match to the cylinder head and block surfaces for consistent compression.
Broad Compatibility: Used on many Briggs & Stratton engines in the 22, 25 and 28 series families — ideal for lawn tractors, walk-behind mowers, generators and other outdoor equipment.
Direct Replacement: Supersedes earlier head gasket part numbers such as 270796, 271075 and 271866 without modification.
Why It Matters:
A properly sealed combustion chamber is essential for engine efficiency and durability. A worn or damaged head gasket can lead to loss of compression, overheating, rough running, hard starting and fluid leakage — symptoms that compromise performance and may cause long-term engine harm. Replacing the old gasket with this genuine 271866S unit helps restore engine sealing, improve combustion efficiency and support smoother, more reliable operation.
Ideal for top-end rebuilds, head removal services (e.g., for decoking or valve adjustments) or any maintenance involving the cylinder head, this gasket is a cost-effective way to keep your Briggs & Stratton-powered equipment performing at its best.
