    Ok, excuse my ignorance: what do the numbers like 1350 or 1410 mean for yokes? And what do numbers like 4340 mean for shafts? I see High Angle offering 1410 and 1480 yokes and what's the difference. Or Superior advertising 4340 Chromo shafts? What do the #'s mean?!:confused:

    1350,1410,1480 are all in reference to the size of the u-joint. As far as I know it doesnt equate to any specific measurement or dimension just a reference for a particular size. Your 4340 shafts refer to the grade of matieriel being used. In that particular case it is 4340 chormoly steel. There are websites that show the dimensions for each type of u-joint. http://www.4xshaft.com/MeasuringGuide.pdf is a pretty good reference to u-joints.
