FK-6609 – Marzocchi 40mm Fork Seal Kit This seal kit includes upper wipers and lower oil seals for the Marzocchi 40mm Monster suspension fork. Superior performance from superior materials and design. Enduro fork seals feature dual-lip Polyurethane wipers and oil seals that solve the problems with standard rubber seal designs like stiction and contamination. They keep the dirt out and the oil inside. Enduro Bearings wipers seal better, move faster, are slicker, last longer, and run quieter than stock wipers. Moly Disulphide lubricated lower oil seals move freer, while never leaking a drop of oil, providing smooth performance over longer periods without maintenance. Enduro Fork Seals are available for most major brands and models of suspension forks at substantial savings and improvement over stock wipers. We also manufacture and stock seals for many suspension forks that are no longer supported by the original manufacturer, so you can keep that old fork running smoothly.
