How does this kit stop metal shavings from circulating?

Worn lifter buckets can abrade and flake, introducing metal contaminants into the fuel pump and the lubrication circuit. Replacing the lifter bucket removes the deteriorating part and prevents additional metal debris from entering the system.

• Includes a new lifter valve bucket engineered to the OEM profile for correct clearance.
• Comes with an O-ring to restore a sealed connection and prevent leaks.
• Includes a fuel line crush washer to ensure a tight fuel line connection.

Will installing this kit prevent camshaft or pump failure?

Replacing the lifter bucket is a preventative step that lowers the risk of camshaft wear and fuel pump contamination associated with metal particles. While no part can guarantee complete prevention, timely replacement reduces exposure to the primary source of the problem.

• Removes the worn component that generates metal debris.
• Restores proper lifter geometry to reduce stress on cam lobes.
• Helps maintain cleaner fuel and oil passages for longer component life.
