Video Transcript for Review of Universal Group Trailer Leaf Spring Suspension - Springs - SP-072275

Today we're going to take a look at the 3-leaf double-eye leaf spring for 3,300-pound trailer axles. Now this leaf spring will act as part of your trailer suspension system, provides the attachment point for your trailer axle. The multiple leafs will allow flexibility to absorb road shock, allows for a nice smooth ride, it will reduce wear and tear on your trailer. And it'll even ensure a nice level ride on bumpy and uneven surfaces. It has a sturdy steel construction. You can see the nylon bushings, they're installed.

They are included. Now pre-mounted hangers or aftermarket hanger kits we do sell separately on our website. They are required for installation. And this spring attaches to a hanger mounted on the trailer frame at one end. And on the other end, it'll connect to shackle straps suspended from the hanger or equalizer.

This is for quantity of one leaf spring.The spring capacity is 1,650 pounds. So when it's matched with one on the other side of the axle, it'll match the 3,300-pound axle capacity. A few dimensions I want to give you. The length, which on a leaf spring is always measured from the center of this spring eye to the center of this spring eye. So if we put our tape measure on it, there's your 18-5/16 of an inch length.

The spring width, it's going to be right at 1-3/4 inches. Now the eye diameter, with the bushing in it, is 9/16 of an inch. If the bushing's not in there, it's 7/8 of an inch. Each leaf thickness is about 3/8 of an inch. And of course, we mentioned it is three leafs.

The number of leafs on this spring. But that should do it for the review on the 3-leaf double-eye leaf spring for 3,300-pound trailer axles..

They could not have possibly shipped the item any faster. I scoured the internet in search for an odd sized spring, they had it in stock and it arrived exactly as described waay before it should have arrived considering I cheaped out on the shipping. I couldnt be any happier with my order. Too bad all businesses cant get it as right. Sorry, I did not take any pictures to upload for my review

  • Which Double-Eye Leaf Springs Are Suitable For 5,500lb Tandem Trailer?
    The 3-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 23-1/2" # SP-113275 is rated for 1,000lbs each, and since there are two springs per axle the weight capacity would be 2,000lbs per axle. This would not be sufficient for your 5,500lb trailer so you would want a heavier duty leaf spring. I see you ordered 4 of these leaf springs which tells me you likely have a tandem 2 axle trailer.
