Mark Williams introduces a new series of DUAL Angular Contact Ball / Ball Bearing Pinion Support Assemblies for 9″ Ford Thirdmembers. The new dual angular contact bearings reduce friction and increase RPM capacity. All assemblies are factory pre-load set to simplify the installation. These M-W exclusive bearings make pre-load adjustments easy for field service by allowing the removal of the front race. Upgrade options include ceramic ball conversion and Nano-Grey (tungsten disulfide) surface treatment processing for additional friction reduction.

Models are available to fit 9″ and 9 1/2″ ring gears for 28 tooth pinion splines. Models for 35 tooth pinion splines will be available soon.
