Line2Line Skirt Coating Info:
We’re excited to announce that Line2Line abradable skirt coating is now available on our custom piston kits.

Line2Line’s proven coating technology represents a major advancement in aftermarket piston performance. Their proprietary abradable coating is applied at a controlled thickness and precisely conforms to optimal geometry during engine break-in, creating an ideal piston-to-bore relationship.

This process allows for tighter operational clearances while providing durable skirt protection and improved lubrication characteristics. The coating helps retain oil, reduce friction, and minimize piston slap and ring flutter compared to uncoated pistons — resulting in improved ring seal and reduced wear on both pistons and rings.

Key Benefits
• Stabilizes the piston within the bore for improved ring seal
• Reduces piston slap and helps prevent false knock detection
• Protects piston skirts from scuffing
• Enhances oil retention on contact surfaces
• Reduces friction for smoother operation
• Promotes hydrodynamic sliding under load

This upgrade delivers measurable improvements in durability, efficiency, and overall engine performance.
