Hey guys going to be replacing the crap plastic gears in my jato tranny. I've found two sets one is all hardend steel and one is Aluminum. Both by hot racing weight really isn't a concern considering my jato is 100% aluminum. I'm just wondering if there is any advantage to either. I'm assume the hardended steel would hold up better but before I spend the money id like a few opinions if possible . Thanks for your time guys.
