Genuine MMR Performance O-Ring replacement set for the MMR Performance M22x1.5 Magnetic Differential Plug. Does not include MMR differential plug, only a set of 5 replacement O-Rings. We recommend you replace the O-Ring any time you service your differential fluid in order to maintain the integrity of the sealing properties it was designed to provide.

As it's a direct replacement with the original O-Ring supplied, it's a very straightforward process to swap and replace.
