What is the benefit of the nickel silicon carbide (NSC) electroplate bore?

The NSC electroplate bore allows for tighter manufacturing tolerances and lower friction within the cylinder. This process also contributes to extreme durability, helping your engine perform reliably for longer.

What components are included in this cylinder kit?

This kit includes a Cylinder Works cast aluminum cylinder with an NSC electroplate bore, a Vertex piston, and all the gaskets required for installation to restore your engine.

Why is diamond honing important for the cylinder bore?

Diamond honing creates the precise surface finish and exact dimensions needed for the piston rings to seal properly against the cylinder wall. This also ensures optimal oil retention, which is critical for lubrication and preventing premature wear.
