Just for comparison here is the FlexTek weight:
Good afternoon Mark,
Our arms for the E-maxx are as follows:
Upper = 36.17 grams or 1.28 oz
Lower = 44.55 grams or 1.43 oz
These are including the pillow ball inserts, shock mounts, and hinge pin bushings installed.
Hope this helps!
Sincerely,
Michael Bethman
