Most trac bars just run the bottom bar so when the axle torques it pushes on the bottom bar and keeps the pinion from rotating upwards. if you only had on ebar on top you woul dbe pulling on the bars rather than pushing. when the axle is already pushing on the leaf springs forward propelling the truck forward i would think that woould be alot of stress going back and forth between leaf spring and top only trac bar. bottom only bars you can pre load for specific suspension heights and loads. running a top and bottom "ladder bar" i would think would be very stong and take the best of both but then could bind with the arc of leaf springs if they were not the same length and angle of leafs. picure a $ link suspension with 20" top bars " leaf springs" and 30" bottom bars "ladder bars" that makes stuff bind make it into a triangle effect instead of palalelle. sorry for the rant but when i build my set of trac bars next weekend they are going to be bottom mount only and go to around the back of the cab.
