Engine Block Expansion Plugs

Speedmaster™ freeze plugs will not rot out, like lower cost steel ones. Your new engine assembly deserves the best. Don’t get stuck trying to replace a leaking steel freeze plug behind a motor mount a year or two from now! These kits include all of the necessary external block freeze plugs, and cam and oil galley plugs for one complete engine.
