Hi FJ40 lovers,
I just got a new set of 4.88´s for my FJ40 and surfing through bobby long´s web got the idea to do a heat treatment to this new set. It´s supposed to make the R&P much stronger.
Do you know what type of steel this pieces are made of? 4340? What´s the stock RC hardness and how much would be wise to increase with this treatment?
I´m in Chile btw, that´s why I didn´t send them to Bobby in the first place.
Pule
