To be honest I dont know. These were bought new, for a completely new engine combo that I had. I wanted the most out of the combo and didnt want to leave anything on the table. There is a thread in the drag section about straight cut gears and like every other mod, there are differences in opinions. I bought them because I could afford them and wanted them. I can also afford not to sell them, so unless someone gives me a decent offer, they can sit in the garage on the shelf where they have been since November.
