Had to finally replace the seals on the 48MM Marzocchi. Bought a pair of SKF and found the press fit into the tube was loose. I also had a pair of 48MM MSR for my KTM and the package also said for Gas Gas. These too were loose. I wrapped a little teflon tape around the SKF seals and they pressed in fine. Rode wth them and eveythig is sealed tight. I would also point out that he stock selas were pressed in tight and needed a normal amount of force to remove. I'm not sure what brand the stock seals are but I will go back to stock on next change. Would like to hear what others experience.
