Upgrade your Cummins engine with our precision-engineered Billet Side Freeze Plug Kit, designed to fit all 1989–present 5.9L and 6.7L Cummins engine blocks. Each plug is CNC-machined from high-quality billet aluminum for superior strength, reliability, and leak-free performance. 

Kit Includes:

• Three precision-machined billet side freeze plugs

• High-temp O-rings for a secure seal

• Copper sealing washers

• Stainless steel Allen bolts

Fitment & Installation:

• 5.9L 12-Valve and 24-Valve Cummins: Install the T-bar with the flat side facing outward toward the block.

• 6.7L Cummins: The solid steel T-bar features an angled face designed to match the factory casting inside the water jacket. Install it vertically, ensuring the angled face aligns with the casting for a perfect fit and seal.

Built to handle extreme conditions, this billet plug kit eliminates the risk of blown-out factory plugs and provides a clean, professional appearance for your engine build.
