Here is my setup:
Travis G calls these traction bars "42 footers" but they are really only 91" (which is longer than I thought I was going to go.
The tubing is 2" OD DOM .25" wall.. They didn't seem to flex at all down in Union Grove, and the tires didn't rub all the paint off the fenders!
Please note, these bars were NOT made for appearance! They will be prettied up later.
There will also be a 3rd 5/8's bolt put through the frame in the 1/4" plate you see.. Didn't have time to drill it.
