Lubelocker was started with a love for the off-road community and a dream to truly innovate the way people could quickly service their differential. For years LubeLocker provided exceptional differential gaskets. Recently the company has expanded the vision to provide exceptional gaskets for multiple platforms. As of this moment, LubeLocker manufactures the highest quality Differential Gaskets and Transmission Pan Gaskets with more and more coming. The team at LubeLocker believes you have more important things to do than worry about how good of a seal your diff or transmission has. That is why they stand behind every product going out of this facility. All LubeLocker Gaskets are proudly manufactured 100% in the United States of America.
