Everything was good. I’m a satisfied customer. I spent the weekend plowing fields, and I periodically checked the bolts for security, hold and performance. Those bolts are under a tremendous amount of pressure, and they performed perfectly as needed. Thanks!
If you have a 1 ton truck like I do and you are putting 4 inch blocks in the back 'cause you are installing a 7.5 inch lift, and you want to keep your overload top springs, then you need these u-bolts. The 3/4 inch u-bolts are the same as the factory installed, and if you get 16 inch long then you can keep all of your leaf springs. Most lift kits only come with 5/8 inch u-bolts which might technically be strong enough, but I wanted to stay with the factory 3/4 bolts size. I couldn't be happier with these u-bolts, thank you uboltstore.com.
Using them to hold 2 - 6”x6”x 24’ timbers onto the forks of my tractor. I’m using this setup to dredge the plant growth from my pond. Works great, Thanks
The uboltstore sent me an unusual ubolt, washers and nuts so I could stabilize my drawbar on my tractor when using it as a trailer hitch. I was trying to find the most economic, simple but strongest way possible for quickly hooking up and removing it. They immediately shipped it and it came fast and in great shape. They are a great source for ubolts and service is top notch. I highly recommend them
Absolutely excellent custom u-bolts. We couldn’t have completed our build on this old farm truck without them!! Thank you, Don
What y’all sent me was not 3/4 of inch it’s only 5/8 of inch
I needed very long u-bolts for a special project. These are perfect and arrived quickly. Thank you for a great product!
Everything was prefect. Thanks,
Was on a time crunch and your fast service was outstanding. The reason for not getting 5 stars one of the bolts was bent in in the center. Just took a little more effort to install. Still very happy with your service. Thank you
it fit like a was supposed too
Everything was perfect thank you
All good!
Just what I ordered.
Ordered U bolts for the rear leaf springs on my 1969 C50 truck and these fit great. Definitely will be coming back for any future u bolt needs.
Reasonably fast delivery, new U bolt, nut and washers. All good Thanks
excellent product and fit
Great price, and got to me much faster than I thought! Top notch quality!
Awesome, beefy u bolts!!! I wasn’t happy with the U bolts that I received with a lift kit that I ordered. The new bolts I received from the U-bolt store were exactly the 1 ton thickness that I was looking for. A great product for a great price.
Work great, I ordered two more and they fit perfect.
I was looking for specific size of U Bolts and did a Google search and one of the searches that came up was the U Bolt store online. The reviews were all positive so based on that, I put in an order. Communication was great as they did not have the nuts in stock, but they reached out to via email and asked if u bolts sent separate or wait until they came in on Tuesday. I said to wait and send them all together. U bolts arrived and they look awesome! If I need special U bolts in the future, I will be a returning customer!
The U-bolts were sized perfectly and arrived quickly!
Perfect size
Haven't installed yet but looks like a quality product and I received it quickly.
Tighten to spec and u bolt broke
Had some bad luck at shipping but the problem was taken care of quickly
Extremely fast shipping and everything came as expected. Seems like a great product!
It fit
Top quality and prompt shipping. Will definitely order again if the need arises. Also the price was best I could find. Grade 8 U bolt for less money than competitors grade 5 U bolts. Thanks!
It was easy to order exactly what I needed, and I got exactly what I ordered. Thank you.
very good quality

Good quality product! I'm going to order 3 more.
I haven't installed them yet, but they fit over the saddle correctly and have the correct measurements.
