Ok, I have located a couple diff types of traction bars and they seem to be diff lengths going forward from the rear axle. So my question to you all with traction bars already or knowledge of is when your out four wheeling and you come to a ridge or something 2'+ tall do the bars hit and if so do they bend? What is the performance diff between shorter or longer traction bars. And is there a performance diff whether the front anchor point is to the leaf springs mounting bolt or to the frame up about where the cab and bed meat? Last question(for now), the shorter pair talked about able to adjust the pre-load on them. Do they all have that option and what diff does that mean/make with or with out pre-load?(ok to that was really 2 questions) THX!
