Re: Anti-wrap spring perches

If I needed to change spring perches on a 14-bolt I'd buy these because they are built heavy. Axle wrap is the warping of the spring due to being the point to absorb the torque between the tires (bolted rigid to the axle) grabbing traction and the vehicle. These will have a negligible affect on that,if any at all. They re still attached to the axle and don't span the spring length enough to have any affect. Figure the flex in the spring is greatest at the mid point between eye and axle. Traction bars form a rigid link between the axle and frame as far as axle rotation goes
