3107F1020 Meritor clutch collar is a genuine Meritor part. Our parts manual lists it as the main differential lock clutch collar, and as a shift collar in the service kits. A differential lock collar slides to lock the differential so both axle shafts turn together, which adds traction when grip is poor. A shift fork moves it, so the splines and shift groove have to be in good shape for it to engage and release cleanly. It is listed, one per assembly, in the Meritor 160/161/164 Series, RD-23-160, RT-40-160, RT-46-160 and RT-46-164EH drive axles. Call us to confirm proper fit for your axle build.
