Trailer suspension is composed of several components that work together to give your trailer a smooth ride. Suspension systems absorb shock from the road and reduce wear and tear on your trailer. They also help to keep your trailer level when you encounter bumpy roads and uneven surfaces.
Differences Between Slipper Spring Systems and Double-Eye Spring Systems
Hangers are the system's point of attachment to the trailer.
Types of Hangers
Leaf springs act as the shock absorbers of the suspension system. Their flexing action when you go over bumps and rough roads smooths the trailer ride.
Used for multi-axle systems, equalizers are designed to transfer from one axle to another the additional load resulting from bumps. The transfer of load serves to equalize the weight being carried by all axles at the time of impact. Without an equalizer, going over a bump would cause one axle to have a disproportional amount of weight on it. Also, the equalizer allows for a smooth transfer of the impact through the suspension system under the trailer.
Replacing Shackle Bolts
U-bolts are designed to secure the leaf springs to the axle of the trailer.
Typical Axle Diameters Based on Axle Capacity
*Note: Number of keeper bolts necessary can vary depending on the type of rear hangers being used.
