Review of Dexter Trailer Axles T3584F-EZ-8974

Today we're going to review part number T3584F-EZ-8974. This is the Dexter Trailer Axle with the EZ Lube spindles and a 3500 pound weight capacity. Now this axle beam will act as part of your trailer suspension system. This will be used to replace an axle on your trailer. It is made of a high strained steel construction. Now also, axles are built with a predetermined bend in the tube that will compensate for the expected deflection under load.

So if you look at this axle actually, in the very middle, I got it sitting in it's position, it will raise up in the middle, and there's actually room underneath there. So it has that predetermined bend, and basically that bend in the axle will help create a 0 camber angle for even road to tread contact across the width of your trailer's tires. This is best for straight line acceleration and steady controlled towing. Now this axle is also a high strained steel construction. It is an under slung design. Basically, the spring seats, the one right here, you can see that seat right here.

And then there's one on this end. They are welded to the underside of the axle for mounting your leash springs too. Now the leash springs we do sell separately. Basically, the under slung design will make a low ride height, which makes it easier to load, and unload your trailer. Now this axle has the straight EZ Lube spindles. There's no drop to it.

They have the built in grease zerk fittings on each end. Basically that will allow you to lubricate the bearings by putting a grease spin on that zerk fitting. The spindle nut, the nut retainer, and de-washer come also with this axle. The spring seats, the brake flanges, the four bolt break flanges, and the spindles are all welded on. The weight capacity on this is 3500 pounds. There are multiple ways to measure the length of an axle beam, but the hub face to hub face and spring center to spring center lengths are your most accurate.

The hub face will refer to the length of the axle when it's measured from the base of one wheel stud to the base of the wheel stud on the opposite side of the axle. So your hubs would have to mounted and you then you would measure from the base of the one wheel stud on your hub to the base of the other side. Now the spring center is the approximate width of your trailer. It's measured from the center of the spring seat on one side, to the center of the spring seat on the other side. So just to give you an idea on this axle, we'll first do the hub face to hub face measurement. Now I don't have the hubs on here but I'm going to give you a rough idea where they will be. So the hub face to hub face length for this axle would be 89 inches. Now the spring center to spring center length. We'll measure from the center to the center, is going to be 74 inches. Now there is a flange to flange length. Which is basically the brake flange to brake flange length. That's not as arcurate as the other ones. But it can be used if you're replacing an axle on your trailer. In this case it's 82 5/8 inches flange to flange length. Now the tubing outer diameter on this is 2 3/8 inches diameter, spindle size is 1 1/16 and again the brake flange is a four bolt design. Now one other note I wanted to mention to you, if you'll notice this sticker right over here, this white sticker. This is the manufacturer sticker. Now this will always face the rear of the trailer. So this axle when it's positioned, this will face the rear. So this would be the left side of the trailer, this would be the right side of the trailer. The reason I mention that is you'll notice there's two loops of wire, one here, one on that side. So the wiring on a trailer will usually come down this left side and you'll tie it into that wire there. So on the left side it will connect to the electric brakes and the wiring on the trailer and that wire runs through the axle and over here on the right side, the wiring will just connect to the brakes. That should do it for the review on part number T3584F-EZ-8974 the Dexter Trailer Axle with the EZ Lube Spindle and a 3500 pound weight capacity. .

Yup! As long as the weight rating, hub-face, and spring-center specs are the same you're good to go!
