Cometic Rocker Base Gasket Set for Harley-Davidson Evolution

Cometic rocker base gaskets are made for Harley-Davidson Evolution big twin engines. They seal the rocker box base (rocker cover) to the cylinder head. The one-piece design helps keep oil in the top end and keeps the joint leak-free through heat cycles and engine vibration. Use them for a rocker box reseal, a top-end rebuild, or routine gasket replacement.

Key Features:

• One-piece Evolution rocker base design replaces the multi-piece sealing arrangement with a single gasket
• Embossed, Viton-coated steel construction gives a durable, resilient seal on the mating surfaces
• Fuel- and oil-resistant materials that resist creeping, cracking and becoming brittle
• Extreme Sealing Technology (EST) design from Cometic, a specialist in performance engine gaskets
• American-made quality engineered for stock rebuilds and performance builds

Cometic designs its gaskets around the sealing environment, choosing the material and technology to suit the application. These rocker base gaskets are a dependable way to restore a clean, oil-tight top end on your Evolution engine.
