Speedway has a 4130 crome moly tierod in the garage sale section that is my perfect and odd ball measurement. It looks extra beefy, but I am confused. I always thought molt was often thinner because it is sronger. , but this thing looks pretty large in diamator. Is this ok for street apps? Is 4130 moly stronger than a normal tierod? ALl help appreciated. Pork
4130 is a Hi-Tensile steel. I don't know why anyone would use steel of that calibre and strength for a tie rod, it's about four times more expensive than what is needed. If you did buy it it would never fail due to strength issues, LOL.
GENERALLY 4130 "n" IS ABOUT TWICE THE STRENGTH OF "MILD" STEEL. ITS AVAILABLE IN THIN WALL BECAUSE ITS MADE FOR AIRCRAFT USE. 4130 IS OFTEN USED IN RACE CARS BECAUSE IT IS STRONG AND WELDS WELL. IT IS STRONGER THAN YOU NEED FOR A STREET TIE ROD. REMEMBER, HENRY MADE HIS TIE RODS FROM FOULDED MILD STEEL.
Thanks all. Something seems wrong, as they (speedway) are offering this moli tierod cheaper than a mild steel one. At first, I thought is was a "garage sale" deal, but when I went back to the site, turns out, it is their common product price, no discount. says right intehtitle, "4130 moly tie rod. You can get them in a variety of sizes from 38 to 52 inches, and they are 38 bucks if crome-moly and 24 bucks if just moly (I guess un-buffed). Now why would they sell a product with such price difference for cheap? Overstock, maybe? Thanks for the responses, Pork
crome-moly/moly/4130 generally all mean the same thing. 4130 is crome-moly steel. "41" means its an alloy of chromium and molybdenum and the "30" means it has 3.0% carbon content.
