Features to know about

Solid Connection That Keeps the Axle in Place: 3/16" Thick Steel Plate Handles 2,000 lbs

A secure axle mount makes all the difference when you’re towing. This Dexter U-bolt plate locks one end of a 1-3/4" diameter axle firmly to a 1-3/4" wide leaf spring. The 3/16" thick steel construction gives it the strength to handle 2,000-lb heavy-duty Dexter axles, so your suspension stays tight and steady mile after mile.

Built for the Right Fit: Precise Hole Spacing for Simple Alignment

Getting your axle and springs to line up is easy with this plate. The holes are drilled right where they need to be—2-1/4" center-to-center between mounting holes, with 3/8" bolt holes that match the required 3/8" diameter U-bolts (sold separately). There’s also a 5/8" center bolt hole to seat the spring pack snugly. Everything fits cleanly, making setup straightforward and reliable.

Strong Base for Smooth Suspension: Heavy Steel Keeps the Setup Tight

This plate forms part of the suspension system that keeps your trailer tracking straight and riding smooth. Its solid 3/16" thick steel resists bending or flexing under load, keeping the axle clamped evenly to the spring. That strength helps your suspension do its job—absorbing bumps and keeping the trailer stable on the road.

Compact Design That Works Where You Need It: 3-1/4" x 4-3/16" Overall Size

At 3-1/4" wide and 4-3/16" long, the plate is small but tough, giving you a sturdy mount point without extra bulk. It’s a dependable piece of hardware that ties your suspension together so the axle, springs, and frame all stay working as one solid unit.

Video Transcript for Dexter U-Bolt Plate for 1-3/4" Round Axle Spec Review

Today, we're going to take a look at the Dexter U-bolt Plate for the one and three-quarter inch round axle with the one and three-quarter inch wide springs. Now this U-bolt plate is for the 2,000 pound axles. This U-bolt plate acts as part of a trailer suspension system. It'll help you secure a one and three-quarter inch diameter axle to a one and three-quarter inch wide leaf spring. Now it does require two three-eighths inch diameter U-bolts, which are sold separately. The thickness on this plate is three-sixteenths of an inch.

It's a steel construction. It's very strong.A few specs on this, I want to give you some measurements. The overall width on this is going to be right at three and a quarter inches. The length is going to be right at four and 3/16 of an inch. Now, these four holes here where the U-bolts go through, the diameter on those holes are three-eighths of an inch.

The large hole in the center is right at five-eighths of an inch. The distance between those smaller holes where the U-bolts go is two and a quarter center to center, and also that way, two and a quarter inches. But that should do it for the review on the Dexter U-bolt Plate for one and three-quarter inch round axle with the one and three-quarter inch wide springs..

The customer service was outstanding. Thru the process of identifying what I needed to ordering and delivering the products I dealt with multiple Customer Service Representatives (CSR). Everyone of them were helpful and courteous. I really appreciated the follow up after my initial contact with CSR. Once the product was ordered I was kept up to date on the status of the order thru regular emails from an etrailer CSR. The parts arrived as they promised, and a CSR even followed up with me after that. Great service, keep it up!

Other than the parts taking a month to process, once they were gathered and packaged, they were delivered within 2 days! I replaced both sides with new 3-leaf double eye springs, 4 shackle straps, 6 shackle bolts, 2 Dexter U-bolt plates, and 2 U-bolts. They were really easy to replace and I did it quickly. Looks great, gonna take her out soon.

I am building a unique little project that I needed extra spring plates for. I naturally came to etrailer and they didn't disappoint. As always, easy ordering, quick shipping, good people, great product.

See what our Experts say about this Dexter Trailer Suspension Parts

  • Determining U-Bolt Length Needed For 1-3/4" Round Axle When Changing Leaf Springs
    You can determine the correct length U-bolts by adding the dimensions of your axle and components. Knowing that the axle is 1-3/4" round you can add that to the height of the Spring Seat # TRSS175 (9/16"). Then you will need to also add the height of the U-Bolt Plate # 012-040-00 (3/16"), washer and nut (1/2") and your leaf spring (?). Without the leaf spring you are looking at 3". We have the U-Bolt Kit # APUBR-10 that uses 4-1/4" U-bolts that will allow you a leaf spring that is up...
