Had trouble finding a U-Bolt that was 8 in long to allow the swivel wheel to turn freely. This one worked great. Thank you
Thanks for a quick response to shipping U-bolts. They were used to attach a level indicator on a John Deere loader.
Perfect fit, no issues what so ever, and very quick turnaround.

Wanted to add a rear sway bar to my classic Nova but as you can see in first photo the 3-1/8” u bolts sent from mfg’r wouldn’t work with the mounting location reqd for my 9” differential. (Happens when you’re using Ford axle on a Chevy) and after measuring approx where I needed the mounts to go - I decided to order both 4” and 3-3/4” x 3/8 ubolts to make sure the mounts would fit rather than order a 2nd set. (3-3/4” were the ticket 👍). So with a little grinding on my part - the mounts fit perfectly and the car should enjoy a better ride! Thanks for a great job and fast turn around to help me get this project completed quicker. Ron.
Fit correctly and delivered on time. Definitely recommend to friends.
Needed longer U bolts for the steering stabilizers. Worked as intended. And did the axle u bolts awhile back. Great products.
Needed new Ubolts for 1984 Toyota wagon to accommodate lowering blocks on the rear axle. These were the perfect option. Ordering the correct diameter and length were as simple as it could get. Glad I found the Ubolt store!!
Unbolts were exactly what I ordered and as advertised.
Perfect u bolts! Fast delivery, clearly professional! Could not have gone better
Perfect fit for my 97 F350. Thank you!
They had what I needed which I could not fine in my searches. Great product. Installed and tested.
Works perfectly.
Had to bend you both to proper size they were supposed to be two and a half inch not 2 and 5/8.
Worked perfectly. Exactly the size that I needed.
Used them to lower my 1963 falcon. They worked perfect.
I needed some replacement u bolts for my custom electric vehicle. I got the ubolts from here and they work great! They are well made, clean thread no burs or anything, perfect size, shipped fast and the price is reasonable. Also the added convenience of being able to add matched nuts and washers to my order is very nice. The only thing is i wish there was a stainless steel option i would definitely have paid extra to get these in stainless steel. Overall I am very happy and would recommend to anyone for their next ubolt project!
Order 8 inch U- bolts & they did not have the size I requested but they did have the courtesy to inform me I did not want to wait another two weeks for them to get the order in so I want with the next size up. They did not waste any time shipping the U-bolts to me. but I did pay the price difference for the next size up. I do prefer coarse thread instead of fine thread, but they will work for Me.
Exactly what I expected.
Fit was perfect. Made the whole job a piece of cake.
Fortunately I measured correctly and ubolt had the right size so my project worked out. Attaching a black water drain holder to RV bumper.
Perfect..A+++
Service is great as was the last time I ordered Thanks
You had what I needed even looking in my McMaster Carr Supply catelog- they didn't have it , but you did!
Experience was good. The bolts arrived in a short period of time. Evevry thing I ordered was in the box.
First rate!
They fit great for the application I used them for and showed up before the estimated delivery date
The only problem is I ordered the wrong size. It was my bad. I had the wrong diameter should have been 1-3/4”x 6 x 1/2” dia fine.
Fit perfectly
Very fast Service and Shipping Delivery
Order arrived timely and product was perfect!
Worked perfectly for the need. Fast shipping too.
I needed something very specific. I loved you ordering system and they came exactly as ordered. Thank you
Fast and easy. Fit like they should.
Ubolts arrived quicker than expected and were made exactly how I ordered them. Excellent craftsmanship and quality product and this company will be my go to for any future needs.
Workrf great
I had some U-bolt custom made and they did a fantastic job of getting the dimension and length just as I needed.
The U bolt Store provided an excellent product and I was completely satisfied with the service. The only problem I had was with the US Postal service. They misdelivered the the package to the wrong city here in Indiana and since I needed it quickly I had to make an hour and a half drive to go pick it up. US Postal service in Indianapolis has been sketchy at best. My recommendation: use UPS or Fedex.
Easy to order with specific measurements just what I had ordered.. They fit perfectly
