Trailer Suspension Components Trailer Leaf Slipper Spring 1000-7000lbs
Sliding spring
Sliding springs are suitable for all types of trailers, including multi-purpose, marine, travel, dump, and horse trailers. The trailer shoe spring is equipped with a 9/16 "inner diameter nylon sleeve at one end and a radius end sliding end at the other end. Measurements are taken along the surface of the leaf spring to obtain the most accurate measurement results. Due to the flattening of the sliding spring, the end-to-end measurement results may vary over time.
Multiple springs will bend to absorb road vibrations and provide a smooth driving experience
Springs can reduce trailer wear
Springs will help you ride smoothly
9/16 "nylon liner, including springs

Leaf springs are a simple spring form commonly used for wheeled vehicles' suspension. Originally referred to as laminated springs or frame springs, sometimes referred to as semi-elliptical springs, elliptical springs, or cart springs, it is one of the oldest forms of vehicle suspension. A leaf spring is one or more narrow curved thin plates connected to the axle and chassis, which allow the leaf spring to bend vertically in response to the irregularity of the road surface. Horizontal leaf springs are the most commonly used arrangement, extending along the length of the vehicle and installed perpendicular to the wheel axle, but there are also many examples of horizontal leaf springs.

The thickness of the blade varies in a parabolic shape from the center to the end. This design aims to reduce friction between the edges, so there is the only contact between the back and center of the connecting shaft between the blades. Washers can prevent contact with other points. In addition to reducing weight, the main advantage of parabolic springs is their greater flexibility, which translates into higher driving quality, similar to spiral springs; Cost reduction reduces carrying capacity. They are widely used on buses to improve comfort.
Usually, when used in car suspension, the blades support the axle and position/partially position the axle. This can cause problems (such as "axle runout") because the flexibility of the spring makes it difficult to accurately control the unsprung mass of the axle. Some suspension designs use Watt links (or Panhard rods) and radius arms to position the axle and do not have this drawback. This design allows for the use of softer springs for a better cycling experience.
