Brand new second gear for A+ gearboxes. This gear has 26 teeth and has a single groove cut into the teeth. Be careful if you have a later SPI or MPI gearbox, as some of these these second gears had 25 teeth and were marked with two grooves. 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.
