Know longer need them . Was unable to return. Didn't know they were special made for me when I purchased them never got any tracking didn't know if they were shipped or not so I purchased u bolts locally an they showed up shortly after that . Was told I could not return then I offered to pay a restock fee but never got an answer so not happy with the u-bolt have not opened the package

The one photo of the U-boats not extending out of the collar nuts were with 9 inch U-boats, which I made a mistake on adding to Lee Springs making the u bolts short. I’ve then purchased 10 inch U-boats and as you can see from the pictures they extend out of the collar nuts just the way I like. These are excellent bolts and heavy duty washers and collar Nuts are an upgrade from the standard flat washer and nuts half the size as is. Yes I will always use U bolt store for my needs in the future. Easy use website and fast shipping.

The U bolts were excellent and the heavy duty washers and collar nuts were an unexpected surprise. My bad was, I ordered them measuring my old leaf spring stack of four leaf springs. Before the U-boats came, I got the bright idea I would put a new set of the springs on that head six leaf springs which gained a half inch in heigh. However, that meant my U bolts were a half inch shorter extending through the top plate into the nuts. Even though I was 3/4 of a distance of the nut which equaled 9/16 which is good enough for threads, I did like not like having them not stick out of the collar nuts, so I ordered 10 inch bolts.

these are 9/16-18 u bolt. mine were 9/16× 5"×10". I ordered mine a tad long and cut then down as needed to ensure a proper fit. Everything snugged up nice and tight with no slippage, the inside Dimension may look a tad bigger but will tighten up as mud are torqued down.

I run a champion wheel stander and these are the only u-bolts I run.

I ordered 2 u-bolts only because I was not sure of the width, 3" or 3 1/4 width and the length was 7" on both. Well its a good thing that it turned out to be the 3", it was 7" length as I ordered. The 3 1/4" was 8" in length (even tho I ordered 7" ) and would never have worked for me. Please send what is ordered!

9/16 Inch Diameter U-Bolts - Round
Store owner replied: Hey William! If you take a look at the description section for every U-bolt product page we include that "your order may be up to 1.25" longer than ordered length". This is because U-bolt rod lengths are made in even number increments and sometimes it is not possible to get it exactly as ordered, so we increase the length slightly. Glad to hear that everything still worked out though. Thank you!
Looking for tough reliable parts that hold up. You guys delivered.

Worked out pretty good. Had to make spacers because they were quite a bit longer than I needed. Other than that they were great & I would recommend anyone that needed u-bolts to visit you guys. Were delivered quickly & had me back on the road confident in the repair

Everything was perfect except for one little thing. I bought my u-bolts with washers and nuts but you guys sent me three nuts that were the wrong size. Other than that absolutely perfect. Couldn't ask for a better u-bolt

Real review here, you need quality? You need it fast? You need real product with quality threads and nuts, can’t forget the top notch washer they have as well! Around 12$ a u bolt and there’s no minimum…companies like these guys normally charge up to 200$ for a minimum order!! Well not these guys! I ordered one to be sure, sent it straight to me, ordered the set and it’s on the way! Be sure to get your measurements, semi round, round or or square! Companies like the UBOLTSTORE are spread really thin for public buyers, not just for mass production…thanks UBOLTSTORE!!!

I love that I can order this part by the dimensions. Most places dont have dimensions to their U-bolts and you waste a lot of time trying to fine the one that fits. But this store made it easy ! Thanks !
