WE WILL SOON BE DOING ALL ARMS OUT OF DOM JUST TO MAKE EVERYBODY FEEL COMPLETELY SAFE. LET ME ALSO SAY THAT WE HAVE NEVER HAD AN ARM BREAK OR EVEN BEND! EVEN THO IT IS PIPE - THE MECHANICAL PROPERTIES ARE EXTREMELY HIGH FOR THE PURPOSE IT IS SERVING. IF ANYONE HAS ANY QUESTIONS - PLEASE CALL OR SEND US AN E-MAIL.

whos broken a DOM arm? ive had 2 sets of S-10 arms break, but both broke the HR steel 3/16" plates, not the DOM or the welds. they didnt even bend the DOM and wont.
DOM of the same thickness is much better than SCH 40 or 80
I do agree that sch 80 should be plenty stong enough for parts, even sch 40 should as long as the tube is a large diameter.
DOM of the size of 1&1/4x1/4" thick costs about 4.50 a foot. but why not use it, since its very good for strength, looks and welding compatability.
