Overall rating: 4.9 / 5 from 153 reviews.
They were just what I needed for my front axle Dana 44. I was surprised that it did not damage the threads when I had to drive them through the lower brace,were very tough. I also use the washers and nuts. When I do the rear end, I’ll be purchasing again.
Great product and quality. I love how I can order any size, any radius geometry and thee option for nuts and washers. I don't need to look anywhere else! Thank you!
U-Bolts had perfect form, fit, function. Very happy with the service. I purchase them too long and had to cut them down, but the precision from the seller was spot on with what I ordered. Will order again from them when the other side goes out!
Nice U-BOLTS.
Your fine threaded u bolt far surpasses the quality of the original u bolt supplied with this stabilizing clamp. Now I trust it to do its job.
Great quality.Replacing bad rusted ones
What I needed.
works perfect!! will definitely order more in the future!! thanks!!!
Worked Perfectly.
Worked great on my helper springs. I wasn’t able to find the size I needed at any other store. Thanks! 👍🏼
They make what size you need very well-made and fast shipping highly recommend
Needed some u bolts approx 17” long for my 8” lifted 2013 silverado 1500 with traction bars, and this was basically my only option. But a good one as I come to find out. Great quality material, exactly what I ordered, and they shipped really quick. My biggest concern was that I would have to wait longer than I wanted to going this route, but that turned out not to be the case. They come raw with a coating of a rust inhibitor on them which seemed decent, but I cleaned them up and painted black so they don’t start acquiring surface rust right away. Overall solid product and would recommend to anyone in need of custom size U-Bolts for their application.
Parts were as described. Would buy again.
I lifted the front of my 1951 Chevy 3800 with some 3/4" spacers I made, and the original ubolts were too short, only had about half the nut threads engaged, so your 5" ubolts, nuts, and washers worked out perfectly. Now it sits more level and looks a lot better. Thanks for your help! Mike
U bolts were perfect dimensionally, threads were very nice. Overall very good. Would be nice if these were also offered with a corrosion resistant finish of some sort - wouldn’t have to paint before installation. Service and delivery time were excellent.
Every thing was perfect except a little slow in shipping time other than that I will definitely use you again.
They fit perfect, great product.
Customer service was excellent I ended up ordering the wrong size but that was my fault not the company.
Everything came in correct dimensions and was easy to install

The bolts were received in great condition and quickly. The dimensions were exact. I was wondering if you have them in stainless steel. Very happy with your product and will be a returning customer.
I ordered bolts from them and when the tracking said “delivered” but was not actually delivered, I reached out to ubolt store, they directed me to take it up with UPS, when I filed a claim with ups , they reimbursed the ubolt store and told me to take it up with them, it’s been weeks now and still nothing, still out a hundred bucks, still no one from the ubolt store has reached out to me for my bolts or reimbursement. Probably a scam.
perfect
