I cut mine around 58" then you have to add in the hiem joints. So I would say around 62" give or take. I wanted them under all the other things welded to the frame right there and it is where the frame is joint front to back so it looked plenty sturdy right there. I think they made it drive much better. Now when you take off it actually takes off instead of feeling mushy and then launching forwards. Only thing with hiems on both ends is there is added road noise around 35 mph range. Overall I am glad I installed them I just need to find someone to powder coat them and if the road noise gets to bugging me I will throw a poly end at the frame and see how that does.
