the arms for the plate aren't as long at the front range one.  i think they bend were the arms meet the plate.  like right were the welds are from the arms to the plate on the inside.  the plate is 3/8's i believe and the two arms are half inch.  i don't think the arms are bending liek pat said.  the one i have on my truck was on my bosses truck before.  he actualle broke it, but with dual cases and 4.7 in the rear and 4.0 in the front there is a lot of torque going through it.  i grabbed it out of the dumbster and welded it back together then plated it.  it has been good for 2 trips so far.
