While Ultimate Unit Bearings seem to last forever, at some point in their lifetime servicing the bearings will be necessary. When that time comes, you can now service your own bearings with this genuine Timken bearing pack.

With a bearing puller, our 2¼ (6.4mm) Spindle Socket, and a little patience simply pull off your old bearing pack and install this new bearing pack in its place. All bearing packs are pre-greased and internally spaced, so outside of checking spindle nut torque at 250 ft-lb (min), theres nothing special to it.

Note: These Bearing Packs require specialist tools to fit. If you do not have the tools, Gigglepin offer a fitting and re-build service for all Ultimate and Pro bearings. Please contact the shop for more details.
