      thicker gasket is much nicer

      thicker gasket is much nicer than stock thin one. no leaks without any sealant. put a little grease on it and it removes without dammage

      A MUST HAVE

      Lowbrow primary gaskets are almost 3 times as thick as others on the market. These gaskets are perfect if theres a slight amount of warpage on the primary cover which is extremely common.
