Review of Universal Group Trailer Suspension SP-212275


Today, we are going to be taking a look at the 4-leaf double-eye spring for 3,500 pound trailer axles. This is made from a strong, durable steel construction. It's going to flex to absorb road shock and provide a smooth ride. It's also going to reduce wear and tear on your trailer. It's going to ensure a level ride on bumpy and uneven surfaces. It's going to mount to the trailer frame with hangers or a hanger kit. Those items are sold separately.

If you are in need of something like that, you can find it right here at etrailer.com. It does include your nylon bushings. One located on each eye, or inside of each eye. The number of leaves that this contains is going to be 4. The spring width is very easy to get. You just measure from outer edge to outer edge.

For this one, we are looking at 1 3/4 of an inch. The spring capacity is 1,750 pounds. This is designed for 3,500 pound trailer axles. The spring length is measuring from the center of one eye to the center of the other. For this particular one, taking a look at that measurement, center on center, we are looking at about 25 1/4 of an inch.

Measuring from the center of one eye to the middle of the spring, that's going to be 12 5/8 of an inch. Then, the spring height, if we take a measurement, basically what I'm going to do is create a straight line from center of eye to center of eye. Then, I'm going to take a measurement from the middle top of the spring to that straight line, and that's going to give us a spring height of around 3 inches. Now, please keep in mind that to ensure proper axle alignment and suspension performance, leaf springs should always be replaced in pairs. That's going to do it for today's look at the 4-leaf double-eye spring for 3,500 pound trailer axles.
