I get mixed results when I've asked about magnafluxing front trailing arms. Some have said do it others have said they crack from the inside out so it doesn't work. What are you beam guys doing?
My arms are write arms,I've already dropped them off to be magged with some other parts. It will be interesting to see how they turn out, I will be sure to get them welded ,can you shed more light on the heat treating process. ThanksI have been racing beam front ends for over 40 years, Mag is not going to tell you anything on a Foddrill arm. What I recommend is clean the arm real well where the gap is at the end of the arm and tig weld it all the way around. I know people who mig weld them with no problem Some re heat treat the arms again I never have and have never had a issue. Outside of buying new arms every so often this way lasts a long time. Of course if you ask Foddrill they will say dont do it but I can tell you all kinds of racers do it and have very good luck. Its a no brainer, if you dont weld the arms its going to break on the inside, by welding them you get twice the strength and you can mag the welded area when you want.. The best arm to find is old write arms, they were the best
