Perfect For:

LS engine rebuilds, engine swaps, performance builds, restoration projects, and any LS application requiring proper engine block sealing. This is a must-have kit during any LS engine assembly or rebuild to ensure reliable sealing and prevent coolant leaks or oil pressure loss.

Why This Kit Matters:

Welch plugs (freeze plugs) seal critical openings in your engine block, preventing coolant leaks and maintaining proper cooling system pressure. The included billet aluminium oil gallery barbell replaces the factory plastic unit that becomes brittle over time, preventing catastrophic oil pressure loss from breakage. This complete kit ensures your LS engine is properly sealed and protected.

Install during engine assembly or rebuild. Professional installation recommended to ensure proper sealing and oil gallery integrity. Follow torque specifications for oil gallery barbell installation.
