Tubular upper arms-I feel lucky tonight

70Hardtop said

I'm not saying a gusset would have saved those particular examples. What i am saying is that it would be general good engineering practice, considering the large loads to use a gusset -otherwise, why would have most other more respected brands have done it? If all the welds are done properly, gussetting can only make them stronger and stiffer. I know i'm not alone in thinking this.

the rms ones that have been on my car since 06 i think it was aren't gusseted. its not needed if welded properly.


the firm feel and magnumforce may need them because where the tube meets the balljoint socket, the angle the tube meets the socket or even the material used. i don't know. look at the difference of where everything is joined.. one thing i can tell ya is that if the broken arms pictured were welded correctly in the first place you would never see a thread liek this in the first place... :)
