High performance Synchronizer Ring for 3rd-6th gear. Also fits reverse. Crafted from hardened steel billet with carbon fiber friction linings to replace the weak cast bronze O.E. synchro rings. The stop cams on the original bronze synchro rings take a real beating from the driver dog window edges of the shift hubs in these transmissions. This is particularly true for 3rd and 4th gears, where the problems most often first appear. Once the edges of the bronze synchro’s stop cams are “dented-in” by the hard steel hub windows, the synchro will be allowed to over-rotate and the outer teeth of the synchro will no longer properly align with those of the shift sleeve and dog ring. In the beginning balky and “scratchy” shifting begin to occur and it becomes harder to “find” the gear. If operation is continued much beyond this point, further damage will quickly result until the offending speed(s) cannot be shifted into at all. Please see accompanying Tech Doc. 0916.1.pdf for more information.
