What does the aftermarket crossmember do? The aftermarket crossmember attaches to the leaf spring hanger and spans to the other side leaf spring hanger. It features an easy attachment with no welding required.  The crossmember is made of high strength, low alloy steel and provides added lateral support to greatly reduce frame stress wherever it is installed. The crossmember provides up to a 90% reduction in lateral strain. This helps make the foundation of the trailer stronger and more secure.

How many crossmembers do I need? A crossmember can be installed at each of the leaf spring hanger locations. On a two axle trailer there are 3 hangers per side, and on a triple axle trailer there are four hangers per side. An owner can install a crossmember at one location or he can install a crossmember at each location if he desires.  We recommend starting at the rear hanger and then moving forward. The rear axle typically sees the most lateral strain, especially when backing in tight to a campsite. If only one crossmember is installed, it should be the rear axle. If two are installed, you would then move to the center hanger. One other factor is whether there is any interference side to side between the hangers. If there is interference, it may be possible to use a drop down adapter kit to help clear the interference (which is usually some type of tank).
