Video Transcript for Redline Trailer Suspension SP01-060 Review

Today we're going to be taking a look at the 3 inch round trailer U-bolts. This U-bolt set, in conjunction with the U-bolt plate, attaches your trailer axle to your leaf springs. It is designed for 3 inch round trailer axles that range in capacity from 5,200 pounds to 7,000 pounds. We can simply tell that it fits a 3 inch round trailer axle by taking a measurement from inside edge to inside edge. We can see that that's going to measure right around 3 inches. The distance that we have from the center of one post to the center of the other, it's going to measure pretty close to 3 1/2 inches, right around 3 and 9/16 to 3 and 5/8.

It does come with the appropriate locknuts, and it's going to have a 1/2 inch diameter. Then the length measurement is measured from the bottom of this section here to the end of the threaded portion, and that's going to measure 7 inches long. That's going to do it for today's look at the 3 inch round trailer U-bolts.

3" Round Trailer U-Bolts (Qty 2) - SP01-060

Average Customer Rating:  5.0 out of 5 stars   (21 Customer Reviews)

These are a great price (nearly 1/3 of my local parts store) and even though they sent the wrong ones the first time, they came very quickly. I would say no more than 7-8 days including the time it took to get the correct u-bolts to my door. The customer service team is very friendly and quick to fix mistakes. The return/reorder was seamless and I got hold of someone on the phone quickly rather than being put on hold for a long period of time. 396891

A year later everything is still working great, glad I didnt waste extra money at the local parts store. These were less than half of the local prices.

All the parts ordered worked great. Susan did a great job in finding a way to get all the u bolts in stock by finding two different sets to put together so I would not have to wait for several to come into stock for my order and at about the same cost. Managed to get the trailer together in time to do a trail work project that was on the schedule before these broke. 397567

Ask the Experts about this Redline Trailer Leaf Spring Suspension


  • Recommendation to Raise Trailer Frame Height for Clearance From Axle
  • You cannot raise your trailer by the method you described. You would instead need to replace your hangers with longer ones or use a system that adds height like the Lippert Components Center Point by Trailair Air-Ride Suspension Upgrade - Tandem Axle # LC1565391 which increases the ride height of your frame by 2 inches. Typically, if you need more clearance from your axle, the Dexter Trailer Springs Over-Under Conversion Kit # K71-385-00 for 3 inch axles is the best route to go. This...

  • Where are Axle U-Bolts Measured From
  • U-bolts like the 3 inch axle U-bolt part # SP01-060 are measured from the inside of the U. So it has 3 inches between the U. Axles have a bow to them that has to always point down otherwise the wheels will be way out of alignment. You will need to have the spring seats of your axle removed and welded to the other side so that you can use it in the configuration you want and have the axle facing the correct direction.

  • Can Trailer Leaf Springs be Moved from Below the Axle to the Top of the Axle
  • Yes, you will need an over-under conversion kit. You can use one of these kits if the trailer uses double-eye springs and the trailer has 2-3/8 inch or 3 inch diameter round axles. (You could use one with slipper spring suspension but the spring seats will have to be fully welded to the axle.) For a 2-3/8 inch round axle use # K71-384-00 and for a 3 inch diameter axle use # K71-385-00. If you cannot use an over/under conversion kit then the only other way to raise the height of the...

  • Lifting Trailer Options and Recommendations
  • Some people will use spacer blocks to lift a trailer if the springs are over the axle. We don't typically recommend that though. We usually recommend either going with an over-under axle kit or going with taller hangers. The diameter of your trailer axle will determine the size of the parts that you will need to order. If your axle is 3 inches diameter, the Dexter Trailer Springs Over-Under Conversion Kit, # K71-385-00, would be a great choice and if your axle is 2-3/8 inch diameter...

  • Can Trailer Axles Be Mounted Above and Below the Leaf Springs on a Trailer
  • The best and safest way to have the axles orientated to the leaf spring is the way the trailer was originally manufactured. The trailer manufacturer will have tested the trailer with the original suspension setup for adequate braking and handling performance. If you flip the axles it could work fine, but since it has never been tested it is hard to say for certain. With that being said, you can have the axles on the top or the bottom of leaf springs. If you do have the axles on top of...

  • Does the Axle Need to Be Supported When Replacing U-Bolts on a Trailer Axle
  • If your axles are above your leaf springs then you can just remove the old u-bolts and then install the new ones. Check out the video I attached that shows this being done. If your axles are below your leaf springs I would recommend you use a jack to support the axle so that it stays in the spring seat so you can remove the old u-bolts and reinstall the new 3 inch Round Trailer U-Bolts Qty 2 # SP01-060 onto your axles. When tightening the u-bolt nuts you will want to use a criss-cross...

  • Should Thread Locker be Used when Installing Trailer Suspension U-bolts
  • Lock nuts alone should have been fine but you could use some Loctite, # LT37614, for extra protection. Make sure to use the blue Loctite and not the red version. The red would make it very, very difficult to remove the nuts. Since you mentioned the lock nuts failed then I recommend replacing not just the nuts but the u-bolts as well. The threads could have been damaged on the u-bolts so it is better to go ahead and replace them. I have included a link to our trailer suspension u-bolt...

  • Is Cut Trailer Wiring Difficult to Reattach
  • I hope they didn't cut the wires as a way to get revenge on you... It's not hard to reattach trailer wiring though. Just use solder and electrical tape or butt end connectors. If the wires were cut the colors would match right up as well as the lengths. I attached a help article that has diagrams and more info on trailer wiring in general.

  • Raising Height of 2016 Shasta Phoenix 5th Wheel Trailer for Compatibility with 2019 Ford F-350
  • The best way for your 2016 Shasta Phoenix to ride level behind your 2019 F-350 is to use the Dexter Trailer Springs Over-Under Conversion Kit # K71-385-00. This will change the springs from riding under your axles to riding on top of them. It will change your overall trailer height by the 3 inch axle diameter as well as the height of your leaf spring stack. After that you will need to adjust the height of your 5th wheel hitch and your pin box to get the level ride you are seeking.

  • What is Needed to Install Spring Seats on Other Side of 3,500 lb Trailer Axle
  • You can have the spring seat removed and installed on the other side of the axle tube, or you could just weld a new spring seat to the other side with # TRSS238. You are correct though, you can't just flip the axle over as the bow of the axle would throw of the alignment.
