There is really no reason to run a pro gear unless you are running a manual trans. You will get better gear life from a heat treated gear. I only run a pro gear in my car because the ratio I use is only available in a pro gear. The 488 gear is very strong. You dont need a pro gear. It will save a few bucks also. The reason the teeth take a set is because of the soft alloy of the steel. They also wear much faster.
