Brand new gear for 4 synchro pre-A+ gearboxes. This gear has 26 teeth and has no grooves cut into the teeth. Often times a crunch while engaging a gear is a result of a failed synchro ring, however if left ignored the gear and selector will start to get damaged. Because second gear is usually the most abused, often times it is where this damage is found first. If you see any chipping or broken selector teeth, pitting on the synchro surface, or any wear on the actual helical teeth, it is time to replace the gear.
