Cappy, I installed the UTF53V10 trac bar from Brazels RV on our 06 F-53.
I wondered about the same thing. I measured the distance between the axel and the axel stops (rubber bumpers)and found that the trac bar had just over a half inch more clearance. So, not a problem. Since both of our bars look the same, are even the same color, and are reportedly manufactured by the same company. I assume the're much the same. Only difference I note from your photo is that my bar's length adjusts from the end next to the frame not the dif-ferential bracket end. Could your bar be mounted in reverse, and therefor higher? Hope this and the above installation link may be of some help. You'll like the difference these bars make, our driveability is now great. Danny
