Devinci Wilson Suspension Bearing Kit for frames with 27.5" wheels and Dave Weagle's "SPLIT PIVOT" design. Includes 8 pcs Enduro MAX (full complement) sealed cartridge bearings, 6 of which have Black Oxide anti-corrosion bearing race treatment. UNLIKE THE FACTORY BEARING KIT, this kit includes all MAX bearings. This means no ball bearing cages/retainers are inside the cartridges, allowing for the MAXimum amount of ball bearings to be installed for greater pivot strength. ALSO INCLUDES both needle bearings and new seals for the rear shock mount.
