For Dana 30 or Dana 27 front differentials 

Anyone who has dealt with RTV knows the hassle: scraping away messy sealant each time you want to pull the cover or service the differential. Old paper or cork gaskets don’t fare much better—they tend to seep, shrink, or require sealant to keep them from leaking. LubeLocker gaskets eliminate both problems.

Built on a durable steel core and finished with a unique elastomer seal bead, these gaskets provide a clean, reliable seal without RTV or adhesives. They install like a traditional gasket but seal like silicone—keeping gear oil in, and water, mud, and dust out.

Why these gaskets stand out

• Installs dry – no silicone required, no messy cleanup
• Seals tight under stress – maintains a leak-free fit even with axle flex, heat cycles, or trail impacts
• Reusable – with clean surfaces and proper torque, they can be used multiple times
• Trail-proven – ideal for Jeeps that see mud, deep water, or frequent inspections and fluid changes

Symptoms that mean it’s time to replace your diff gasket

• Oil spots forming under your Jeep after sitting overnight
• Residue or seepage around the differential cover
• Frequent low gear oil levels
• Visible damage or warping of the old gasket

Fits:

• 1963-1983 Wagoneer
• All with Dana 30 or Dana 27 Front Axle
