Video Transcript for Review of Dexter Axle Trailer Leaf Spring Suspension - Axle Mounting Hardware - 3-66

Jeff Hello everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at this spring seat for a five inch round, 10,000 pound to 15,000 pound trailer axle. Now the spring seat is a necessary component on your trailer suspension system. When this is mounted with a three inch wide leaf spring, it adds the extra support, provides proper positioning for your axle. This is designed to weld onto a round, five inch diameter axle, which are typically the 10,000 to 15,000 pound size axles.

And as we mentioned, it is designed to work with three inch wide springs. The hole cut out right here on the middle of this seat will surround the raised knob on your leaf spring. So your leaf spring will go underneath there and that knob'll go right through there to hold it in. Helps prevent turning or shifting. This will provide extra support and secure positioning for your trailer axle.

Now, one note is two of these spring seats are required for one axle. But that should do it for the review on the spring seat for the five inch round, 10,000 pounds of 15,000 pound trailer axles..

You can just install new spring seats on the side you need like you mentioned. For a spring seat for a 5 inch axle like what you have you'd want the part # 3-66.

  • Can 10K Leaf Springs be Upgraded to 3 Inch Wide 12K Springs for Gooseneck Trailer
    You can definitely upgrade the leaf springs from a 5-leaf 2-1/2" wide system to a 6-leaf 3" wide system but you'll basically need to swap out your whole suspension system. It's also good to note that even if your leaf springs are rated for a higher capacity it won't increase the weight rating of your axles. We don't recommend overloading the trailer but that's obviously up to the end user so I'll let you know what parts you need so you can install the larger springs. On your axle you need...
