The original one like all of them rounded off the head. This fit. Does not come with O-Ring which is really dumb.

Perfect replacement and genuine GM fill plug for front differential on a 2008 Silverado 1500. Mine was so stuck I had to use liquid wrench on it for a week, then use the 1/2" air impact wrench with 18mm socket and 3" extension to finally get the old one off. Transferred the o-ring and used anti-seize compound on the threads and lip that touches the case.

Need to swap over o-ring from old plug or get a new one. Great replacement, used air hammer to tap old plug out, a lot easier than welding a nut on.

Fit perfectly. If you're looking at this page, it's because you need a new plug. Stop thinking about it and just buy it. My only gripe is it doesn't come with a gasket. You have to remove the gasket from the old plug and put it on this one.

Plug fits exactly as it should. The only reason I needed to replace it was because the former owner or owners mechanic rounded the head off! Good as new now. Arrived in one piece.

I love it and hate it at the same time. My old plug rounded because of the stupid design by the GM engineers. They put a huge pipe thread plug which is about 2 inches and stick a small 18mm bolt head on the end. It ended up taking torches and welding a new nut to get the old one off.Now as far as the replacement it's fine. OEM equipment and no issues and fixed my factory problem plug. Make sure to use anti seize on the threads when replacing.
