Hi, everybody, Andy here with etrailer.com. Let's take a look together at this Dexter U-Bolt Kit for mounting 5,200 to 7,000-pound round trailer axles. Now this kit is designed to fit axle diameters of three inches, which is going to be your typical 5,200 to 7,000-pound axles. And this kit includes everything that you see here on my table before me. You're going to receive four seven-inch long U-bolts and then two U-bolt plates for 1 3/4-inch or two-inch springs, and then eight 1/2 inch by 20 nuts. And the spring seats.
Spring seats are required for mounting the axle to the leaf springs, and those are gonna be sold separately from this kit. Now, if we measure from the inside of the U-bolt to the bottom of the bolt post, that's gonna give us our seven-inch measurement. And these are tapered where the axle sits to help the U-bolt stay in place on your axle. And the area between the bolt post measure three inches. So that's where we are...
That's where we get the spring width fitting from. And then the diameter of each one of these bolts measure half an inch. And of course, the plates that are included are designed to fit these U-bolts. Well, that's gonna wrap up our look today. I do hope that it was helpful for you.
Again, my name is Andy, thank you for joining me.

Mount your round, 3" diameter axle to your trailer's leaf springs with this U-bolt kit. U-bolts, plates and nuts included.I upgraded my leaf springs to 4000lbs springs and needed longer axle U bolts and Quinn at etrailer was helpful getting the correct bolts headed my way.
These seem to be working ok but do not appear to be designed for use with the HD upgraded Moryde greaseable shackle kit that I purchased with them . You can see in the photos that they rub and bind
Item showed up not damaged and install was a breeze, I have ordered numerous items from this web site and my only complaint is they are normally very prompt about getting product in the mail and this time it was 3 days. Not that big of a deal I will still use website for ordering products
Excellent product, I used it to beef up the suspension on my welding trailer. It has proven to be a great quality product. Even though local stores carry this kit, I trust a company with the word trailer in its name, and for good reason. I recommend your website to all of my welding students, so if you're ever in the mood to send parts for me to install, test, and review. Please keep me in mind. I'm currently searching for a good 10" electric brake assembly to replace my existing set, and I'm sure I will be reaching out to etrailer for their expertise.
The u-bolts fit and worked perfectly. I didn’t use the included tie plates, my travel trailer has shock absorbers that attach to the tie plates, I reused the originals. I torqued them to 70 ft. lbs. per Dexter axle specifications. I did clean and paint them before installing. I upgraded my 5400 lb. 4-leaf springs to 6000 lb. 5-leaf springs, which required longer u-bolts.
Went together well.
Just installed them a few minutes ago. Great product. I liked the extra ribs in the bottom mounting plates. It seemed to add a great deal of strength. I thought the shipping was a little steep but all in all a good experience. Thank you.
these u bolts and brackets arrived quickly, installed flawlessly, and seemed to be heavy duty.
i couldn't be happier.
Working great. Still doing well after a year of full time travel on a 5th wheel RV.
Wow! I have ordered from etrailer for years. Great products. I ordered this on a Tuesday and received it Thursday and shipping was Free!
Painting them now to match trailer and installing them tomorrow. All within a week. Like I said, Wow!
Quality product. Works perfectly on my 1968 Plymouth leaf springs.
Everything fit together perfectly. Had a few more nuts in the box than I needed but that is better than being short! :-)
A+ works great. Fast shipping if I ever need axle again will buy from you
I will always order my trailer parts from this company they were quality and reliable I've had a lot of cars using their equipment and parts keep up the good work
Have not installed them yet but they look very good. Heavy duty as expected. One u-bolt is a bit twisted fresh out of the box but it should be easy to correct using a vise. Only one of the 8 I bought was this way. Must have slipped past quality control at the factory. It will not affect its integrity or usage.

The kit is working great. No problems with it. Many thousands of miles since the install.
I like the fitment of them. The ease of nutting the u bolt was great. The serrated flange nuts probably won't back off, but I like overkill. I will double nut then due to I think road vibration will loosen them.

After a year it works flawlessly as expected.
Nice Robust suspension parts. I'm however using these for Ham radio antenna Mounts, as i can't find u bolts in this size in the Ham world... Cheers..
Excellent people to work with.
I received what I ordered, and in two business days.
Only problem, was I ordered the wrong size leaf springs and U-bolts.
But, returned them, no problems. Full refund, minus return shipping.
Also, re-ordered. Hopefully, the correct size, this time. (I was three hours away from my trailer the first time I ordered)

Second time was a charm! Good product. Fit perfectly. Thank you!
I pull a toy-hauler 5th wheel trailer between Alaska and the lower 48 through Canada twice a year. Much of the road is rough and caused me to break a leaf spring every trip. Since installing a shock absorber system and upgrading from 5-leaf to 6-leaf springs, I have so far eliminated suspension damages on the route.
Good value and perfect fit.
Perfect for my application
I think you screwed up. I did not receive the U bolt kit, I received Part # CT-3000-RK, Repair kit for 2" straight coupler which I did not order. I reported this upon delivery of the wrong part.

We recently sent you a new u bolt kit and were wondering if you had any feedback about the product for other shoppers? We look forward to hearing from you.
Just what I needed to complete my stock trailer repairs
Super fast service, arrived 4 days early. Packaging was pretty bad but the parts made it and worked great
Ordered 3500# replacement axle for hauling trailer. Works great, perfect size, bolted right up.

I do have two recommendations for you. The first would be to make sure that the bolts are not over tightened. The locknuts should only be tight enough to limit as much movement as possible without binding anything up. The second recommendation is that Lippert makes that can be used with the Equa-Flex system. It is part # LC64FR. The shackle straps are less thick at 0.212 thickness however they are longer at 3 and one quarter inches.
