Video Transcript for Redline Trailer Suspension 1753223 Review

Today, we're going to be taking a look at a replacement U-bolt with nuts for 1 1/2" wide square trailer axles. You would use the U-bolt with a U-bolt plate and an additional U-bolt with the same dimensions to secure an axle to the leaf springs, which are mounted to the trailer frame. This is going to feature a threaded portion on each end. That threaded portion measures about 2" on each side. If we put a ruler on that, you can see that the threaded portion, from the bottom of the post to the top of the thread, measures 2" long. This is designed to fit a square 1 1/2" wide trailer axle. It is for 3500 pound axles only.

It's going to come with the included nuts. The opening is going to measure about 1 1/2", so that's how we can tell it's for 1 1/2" wide trailer axles. The bolt diameter is 1/2". The length from the bottom of that portion, there, to the end of the threaded area is going to measure 5" long. Then, again, that opening is going to give us an inside width measurement of 1 1/2". That's going to do it for today's look at the replacement U-bolt..

I sent for 4 ubolts for my horse trailer because etrailer was the only one who had the right size . I ordered them overnight and they came at 12 so o had time to put them on the next day . I put them on they fit they were the ones I ordered so o saved $680 by using my own trailer and not needing to hire a hauler . I’m extremely happy with my purchase and the speed it got here so I give 5 stars because you guys earned them . Thank you I’d do business with you again in a New York City second ! 679479

Quality Bolt. I will use Etrailer again. I could not find these bolts locally mainly because I work six days a week and the parts suppliers in the area only work five. This made Etrailer a awesome option. Price was the same as the local suppliers and I had the parts in four days allowing me to finish my trailer without having to take time off from work to chase parts, another added savings. Thank you Etrailer. 552872

Ask the Experts about this Redline Trailer Leaf Spring Suspension

Do you have a question about this Trailer Leaf Spring Suspension?


  • Need Replacement Square U-Bolt for 1-1/2 Inch Axle
  • For a replacement U-Bolt closest to your measurements, I have the Replacement U-Bolt with Nuts, part # 1753223, which is for 1-1/2 inch wide, square axles. We also sell these U-Bolts in a pair, part # SP01-120. The Replacement U-Bolt, part # 1753223, will work great with your 1-1/2 Inch, 1800 pound capacity axle. U-Bolts do not typically carry a weight rating.

  • Determine Square Axle Capacity
  • Square axle capacities are pretty hard to determine. Unlike round axles, they do not have set capacities based on their dimensions. We have no information for the bearing numbers you listed. But what you can do is give me some exact measurements of your spindle and we should be able to see if there is a hub we carry that would fit so that you could at least get a ballpark on your capacity. I need the dimensions of where the bearings and seal ride. You might be able to contact the...

  • What is the Axle Capacity for an Old Trailer with Hub # 22834
  • The bearing numbers you have provided indicate that you have hub 22834. This hub is no longer made but there are parts for it such as the bearings # 2788 and # 1779 an the races # 2729 and # 1729. The hub is rated for 2,600 pounds which means it fits a 5,200 pound axle.
    view full answer...

  • What is the Weight Capacity of a Trailer Axle with # L44643 Inner and Outer Trailer Bearings
  • If both the inner and outer bearing are # L44643 bearings, that means it can fit on a BT8 spindle. One BT8 spindle, like # R104BT8, has a capacity of 1,000 pounds. So on a single axle with 2 spindles, it would have a 2,000 pound capacity. The axle and/or trailer capacity should be on a sticker or plate on the trailer tongue.

  • U-Bolt Dimension Measured on Bolt Centers
  • I pulled a Replacement U-Bolt with Nuts # 1753223 from our warehouse to measure the distance between the U-bolts measured on center and found that dimension to be right at 2 inches. Check out the video I attached that shows me taking this measurement with a dial caliper.

  • What is the Torque Requirement for 1/2 Inch U-Bolts for Trailer Suspension
  • According to our FAQ on slipper springs, linked for referenced, the torque specs are as follows: Torque Ratings 1/2 inch Bolts: 45 ft/lbs - 70 ft/lbs 9/16 inch Bolts: 65 ft/lbs - 95 ft/lbs 5/8 inch Bolts: 100 ft/lbs - 120 ft/lbs The Replacement U-Bolt, # 1753223, uses a 1/2 inch nut so it would fall into the 45 to 70 foot pound category.

  • Should Trailer Leaf Springs Be Easy to Move Up and Down
  • If the slipper springs on your trailer have a lower capacity like # WIC2 at 500 pounds apiece, then it would be possible to physically compress them with the trailer empty but it should not be all that easy. With a load on the trailer it will be easier. If you find that you can move the springs then it is probably time for some new ones. On higher capacity springs you probably would not be able to move them at all without a load on the trailer. I have included a link to our slipper...

  • How to Determine Axle Weight Capacities on a Trailer
  • The axle capacity should be stamped on the frame of the trailer near the coupler of the trailer. It also could be listed somewhere on the axle. I wish there was an industry standard weight capacity for the 1.5 inch by 1.5 inch square solid steel axles but there is not. If you do not see a weight capacity listed in either of those places you can remove the hubs on your trailer and give me the bearing numbers that are listed on the spindles. I will be able to tell which hubs and spindles...
