GM Duramax L5P 6.6L CCV Upgrade Kit (2017–2024)

The GM Duramax L5P 6.6L CCV Upgrade Kit offers a complete, high-quality replacement for the factory crankcase ventilation (CCV) system, known for its common failures, in 2017–2024 GMC Sierra and Chevy Silverado HD trucks. This upgrade swaps out the OEM plastic PCV box for durable billet aluminum components, effectively addressing issues like swelling, leaks, and clogging in the original system.

Key Features:

• Precision-Machined Billet Aluminum: All parts are crafted from billet aluminum with perfectly fitting O-rings to guarantee a secure, leak-free installation.

• Complete Kit: Includes all necessary components for a full upgrade—no additional parts required.

• Quick Installation: Typically installs in under an hour, depending on factory bolt removal.

Benefits:

• Resolves Factory Weaknesses: The stock plastic CCV system often swells, clogs, or cracks, which can cause excess crankcase pressure and result in oil leaks from seals and gaskets.

• Enhances Reliability: Eliminates the failure points of the OEM PCV box, helping prevent future oil leaks and engine issues.

• Clean, Professional Appearance: The billet aluminum parts not only perform better but also improve the look of your engine bay.

Installation & Compatibility:

• Designed to fit all 2017–2024 GMC Sierra and Chevy Silverado 2500/3500 HD trucks with the 6.6L Duramax L5P engine.

• Easy to install with basic hand tools, perfect for both DIY mechanics and professional shops.
