Double Eye Vs. Slipper Springs- Which is a Better Choice?

Choosing the best leaf spring system for your trailer from among Double Eye Springs and Slipper Springs, can be a confusing decision. To make an informed decision you need to first understand how both of the systems function. Experts of CamperRepair Merrill Michigan have come up with suggestions to make the decision easier for you.

Double Eye Spring Suspension-

Each end side of the double-eye spring is rolled in the form of an eye or bolt hole. The Spring is attached into the front and rear hangers, and connected in the centre via shackle straps and an equalizer.

Slipper Spring Suspension-

Slipper Springs have an eye on the front side of the spring and an arched open end on the rear, allowing the spring to slip on the equalizer or rear hanger.

Pros of Double Eye Spring Suspension-

1.      Smoother than slipper strings.

2.      Better weight distribution.

3.      More affordable.

Pros of Slipper Spring Suspension-

1.      Less moving parts.

2.      Less bushings to wear.

3.      High-quality and larger bushings in the eyes.

4.      Higher capacity options available up to 7,500 lbs. springs good for a 15K Axle.

Cons of Eye Spring Suspension-

1.      More moving parts.

2.      More bushings to wear.

3.      Small bushing diameter, implying a shorter life span.

4.      Limited weight capacity- Max 3000lbs. springs good for a 6K Axle.

Cons of Spring Suspension-

1.      Makes noise because of the metal on metal where the rear of the spring hits the equalizer/ rear hanger.

2.      Weight distribution is not sufficiently effective between axles.

When it concerns purchasing or repairing your food trailer, you may face some difficulty selecting the right spring suspension for your trailer. You may have to study through a few variables.

For instance, most of the light RVs have the standard double eye suspension because it is a quitter system with minimal steel and it is the more cost effective one among the two systems.

On the contrary, most commercial equipment trailers come with slipper springs because they need a larger amount of weight of capacity and longer wear life in the bushings to go through more regular use.

If you see that capacity is not your problem, and instead the wear of your bushings is, you can hire services for Trailer Repair in Merrill Michigan that will help you extend the service life of your suspension using different bushing materials, greasable bolts, rubber equalizers, and thicker shackle straps.
