S&S Cycle 4.250" Bore Cylinder Base Gaskets

Achieve uncompromising engine sealing and reliability with the S&S Cycle 4.250" Bore Cylinder Base Gaskets. Engineered for demanding motorcycle applications, this pair of high-performance gaskets ensures a robust and long-lasting seal, crucial for maintaining optimal engine compression and preventing leaks.

Description

Designed specifically for engines requiring a 4.250" bore, these S&S Cycle cylinder base gaskets are constructed from the highest-quality fiber-reinforced Aramid Premium material. This advanced composition provides exceptional strength and superior temperature resistance, allowing the gaskets to withstand the extreme heat and pressure generated within high-performance motorcycle engines without failure. Special additives are incorporated to significantly improve extrusion resistance and reduce stress relaxation, ensuring the gasket maintains its integrity and seal over extended periods. This enhancement directly translates to enhanced seal-ability, preventing material creep and maintaining consistent compression.

Further bolstering their reliability, these base gaskets feature a distinctive blue anti-stick compound. This proven formulation actively resists failure due to extrusion or blowout, common issues with lesser quality gaskets. The anti-stick property also facilitates easier installation and removal, preventing the gasket from adhering permanently to engine surfaces and simplifying future maintenance. With a precise thickness of 0.36 mm (0.014") and a stock bolt pattern, these motorcycle base gaskets offer a perfect fit and dependable performance, making them an essential component for any engine rebuild or upgrade.
