Video Transcript for Redline Trailer Suspension UBZC716X212X400 Review

Speaker 1: Today we're taking a look at the replacement U bolt for two inch wide square axles. This replacement U bolt acts as a part of a trailer suspension system. It's used with another U bolt, and a U bolt plate to secure one side of your axle to the leaf spring, which is mounted to your trailer's frame. Another U bolt and U bolt plate are sold separately and available at eTrailer.com if needed. This square bolt fits square axle beams. It's a zinc plated steel construction, it's heavy duty and corrosion resist, so it's great on boat or snowmobile trailers and with this part number you get one U bolt.

It is designed for two inch wide axles. We can tell that by taking a measure from inside edge to inside edge. So if we take that, that measures around 2 1/8 inches, so it's perfect for a two inch wide axle. The length measurement is taken from the bottom of the U to the end of the threads and that measures four inches long and the bolt size, start with the diameter is 7/16 of an inch, that's the diameter of each post right here. So the bolt size is 7/16 by 14.

That's going to do it for today's look at the replacement U bolt for 2 inch wide square axles.

I was looking for a pair of very special size U-bolts for a restoration project. I was having no luck at hardware stores or other sources on-line. I thought I was going to have to fabricate them from scratch until I came upon etrailer.com. They had what I needed. The thread pitch-size and overall dimensions were exactly to the original factory specifications. . The person on the phone was very pleasant and ordering was easy and fast. The U-bolts arrived at my door a day and a half later! The quality was as good as the original bolts from the Ford factory. A perfect fit and the accessory bumper guards were completed. Glad I found the right parts and at a price that was very reasonable. Etrailer has a great selection and offers more choices than their competition. Check it out! Sincerely, Jerry L. ,Lancaster, Pa. 566745

The products etrailer supplies are superior. The only confusing part is when I tried to track it provided a UPS tracking number, however, when it was delivered it came via Post Office so the tracking number never completed its routing foremat. No worries and no problem we got the items fine, but things got shifted in transit for some reason. thanks again! 330121

Great product. The only problem with it, there were no nuts with it. 231539

I used the roller to bolster a keel of a trailerable boat, using a crossbeam of only 2"x2". I ended up using it differently than it was intended, lying on top of the crossbeam instead of on its side, because it fit and because it will be more sturdy in that direction. The U-bolts look OK, but not heavily galvanized, hopefully they will be OK in saltwater. There were no nuts or washers with the U-bolt, my fault, but a surprise. 223597
