1957 Chevy Truck

both of those bars are fighting against the leaf springs. You may not notice any problems on a 2x4 vehicle, but they will cause a lot of problems (especially the one going across) on a 4x4 vehicle that wants and needs articulation of the suspension. Basically, the bars want to move in an arch and the leaf springs only want to move up and down. (yes the leaf springs will move the axle slightly forward, but will still bind with the bar because the pivit points are different.) I guess it was set up that way to reduce axle wrap because of the tall blocks.
