The rods don't bend because they are weak, they are bending because there is either a fault or you are asking them to cope with forces they were not intended for.
Is rods in unmodified cars are bending, it HAS to be some other fault otherwise all stock engines would be blowing, not just a very small percentage.
Forged rods will just hide whatever this fault is.
