All MW spool bearing kits feature Timken® bearings and races. MW also offers special bearing adapters to allow the use of spools for smaller bore sizes to be used in larger bores.MW ring gear bolts are manufactured with a ground shoulder to drive against, while the 12-point bolt heads are drilled to accept aircraft type safety wire. This fool-proof method eliminates the chance of the ring gear bolts loosening and "backing out".
