Single Leaf Length: Refers to the length of the trailer leaf spring, in millimeters (mm). Longer leaf springs are used for trailers that need to bear larger loads.
Width: Refers to the width of the leaf spring, usually in millimeters (mm). The width affects the stability and load-bearing capacity of the spring.
Thickness: The thickness of the leaf spring directly affects its load-bearing capability. Thicker leaf springs can support heavier loads.
Number of Leaves: Indicates how many individual leaves are stacked in the spring pack. Typically, a multi-leaf spring pack offers higher load-bearing capacity and greater flexibility.
Max Load Capacity: The maximum load the leaf spring can safely handle under normal operating conditions, measured in kilograms (kg). The load capacity varies depending on the trailer's intended use.
Application: Different leaf springs are used for different types of trailers and vehicles. Lighter leaf springs are used for standard cargo trailers, while heavy-duty springs are used for transporting heavy loads.

what do leaf springs do
Leaf springs are designed to carry and distribute the weight of the trailer and its cargo evenly across the axle(s). When a trailer is loaded, the leaf springs absorb the load and prevent excessive sagging or stress on other suspension components. The springs help maintain a stable ride height by supporting the weight and ensuring that the trailer doesn't bottom out under heavy loads.
Leaf springs help absorb road shocks and vibrations. As the trailer moves over bumps, potholes, or uneven terrain, the leaf springs compress and expand, reducing the impact of these forces on the trailer’s frame and the cargo. This shock absorption helps maintain a smoother ride, both for the trailer itself and for the vehicle towing it.
Leaf springs contribute to the overall stability of the trailer. By maintaining consistent axle positioning and allowing for some degree of flex, they help keep the trailer level and aligned with the towing vehicle. This reduces the risk of instability, swaying, or fishtailing, especially when driving at high speeds or when carrying heavy loads.
While leaf springs support weight, they also allow for controlled movement between the axle(s) and the trailer frame. This flexibility enables the suspension system to accommodate variations in road surfaces while maintaining proper alignment and handling. Leaf springs allow for vertical movement and slight rotation of the axle, which ensures smooth transitions over uneven surfaces without causing damage to the trailer’s structure.
Leaf springs are known for their durability and long service life, especially in heavy-duty trailers. Made from high-strength steel or composite materials, they are built to withstand the stresses of carrying large loads over long distances. Their simple, robust design makes them easy to maintain and replace, ensuring the trailer remains functional and safe for many years.
Compared to more complex suspension systems (like air ride or coil spring suspensions), leaf springs are relatively inexpensive to produce and maintain. This makes them a cost-effective choice for many types of trailers, from light-duty utility trailers to heavy-duty commercial vehicles.
Single Leaf Spring: Typically found in lighter-duty trailers, this design uses a single, flat spring to support the load.
Multi-Leaf Spring Pack: For heavier-duty trailers, multiple leaves are stacked together to form a spring pack. This design offers more strength and greater load-bearing capacity.
Tandem Leaf Spring: Used in trailers with multiple axles, these systems incorporate two or more spring packs working in tandem to distribute the load across more than one axle.
Trailer leaf springs are essential for providing a smooth, stable, and durable suspension system. They help carry the weight of the trailer and its cargo, absorb shocks from the road, stabilize the trailer, and provide the necessary flexibility for handling varying road conditions. Their simplicity, cost-effectiveness, and long-term reliability make them a popular choice for a wide range of trailer applications.
