Wiseco W5374 .020 Copper Base Gasket Suzuki 1198-1260cc

The Wiseco W5374 is a .020-inch (0.020") copper base gasket engineered for Suzuki engines in the 1198cc–1260cc displacement range. Designed as a direct replacement during top-end rebuilds, this gasket provides a precise, leak-free seal between the cylinder base and engine cases.

Copper base gaskets are a preferred choice for high-performance and rebuilt engines due to copper's excellent thermal conductivity, conformability, and long-term sealing reliability. The .020" thickness allows for fine-tuning of compression ratio during overbore or rebuild applications.

Key Features:

• Material: Copper construction for superior heat dissipation and crush conformability
• Thickness: .020 inch (0.508mm) for precise compression ratio adjustment
• Application: Suzuki engines in the 1198cc–1260cc displacement range
• OEM+ Quality: Engineered to meet or exceed original equipment sealing standards
• Leak-Free Seal: Precision-formed to ensure a reliable, long-lasting seal at the cylinder base
