    Steel spur gear?

    So when I used to have a Savage I had plastic spur gears and was told metal spur fears would blow up the transmission? My new to me Savage X has a steel spur gear and a 3 spd tranny with reverse. Should I swap it out for a plastic or is my 3 spd strong enough and I should be good?
