Spyntec hub conversion kit with Warn hubs for the 1999–2002 Ford F-250 / F-350 Super Duty.
A unit bearing is sealed, non-serviceable and turns whenever the wheel does. When it wears, the whole assembly is replaced. A free-spin conversion swaps that arrangement for fixed spindles with serviceable wheel bearings and manual locking hubs — bearings you can adjust and repack, and a front axle that stops turning when it is not needed.
Spyntec's case for it is straightforward: better fuel economy with the front axle disconnected, less wear on the front driveline, and the strength of a fixed spindle.
It also puts the choice of locking hub back in your hands — a mechanical hub you select rather than a sealed assembly you inherit.
This kit is the 1999–2002 version for trucks with coarse threads, supplied with Warn hubs. Spyntec split this part three ways by year and thread, so confirm yours before ordering.
