Square Trailer U-Bolts
Features:
Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
Today we are reviewing SP01160. This is a set of two 2-inch square trailer U-bolts and they are used with U-bolt plates for 2-inch square axles. Those are sold separately as part number 117594 and that plate, along with these U-bolts will secure the trailer axle to the leaf springs and those are mounted to the trailer frame. So, what you have here are two 9/16th inch diameter bolts that are, here we go, 5-3/4 inches long. The threaded portion right here, as you can see, is 2-1/2 inches long and the diameter, inside-to-inside here, is 2 inches. These bolts do come with the nuts that you will need and that is it for Part Number SP01160 from Redline, 2-inchSquare Trailer U-Bolts.

Great product, as described, description of the measurements fit right on.
I would & have recommend E-trailer to friends.
Etrailer offers galvanized spring plates but in the U bolts, un protected steel bolts and nuts. Makes no sense to have a mixture of galvanized and unprotected parts in the whole assembly!
I bought a can of galvanized spray paint at Home Depot to coat the raw metal parts.
Good thick U bolts, you can get away with about 1.5" of drop using a spacer block in between the spring and the axle. I was planning on 2" of drop but these U bolts are too short. That is my only complaint, and it is my own fault. I didnt know how thick the leaf springs were going to be so I thought these would be long enough, but not with 3500 lb 4 leaf springs.
I have a huge old miley horse trailer that has seen better days and all of the leaf springs, bearings, etc needed to be replaced, It wasnt like I could go into a name brand parts store to get them either. So when my husband told me he found everything he needed on etrailer.com, I was relieved. I am very happy with the price and the delivery time. The fact that delivery was free was definitely a bonus because the parts were very heavy. I was a little worried about the condition of the parts when they came, the boxes were pretty beat up (very heavy) but so far I haven't found any problems.
Erika was super helpful. Really helped me get the correct parts the first time. I will always use etrailer from now on!!
A+++ in my book!

Still on my boat trailer no issues!
Bought everything to completly rebuild my trailer. All products were good quaility and fit perfectly. The outstanding service was the best part. Never have done trailer work before and I called and talked to support. Got me everything I needed and it was all correct. Upgraded my shipping for free and I still recieved my order quicker than they told me I would.
The product was excatly what i thought it would be. The description of the product was spot on. However, the tracking system is poor, almost sophisticated enough for a three year old. Believe me you will want to track your package. If you do not so much time will pass that you may forget you ordered anything. It is possible "the virus" played a part ..... nope! this was real.
Quality is excellent,I wish I had ordered lock nuts and washers as the u bolts just come with standard nuts.I will just use lock tight and check for loose nuts until they get rusty.If you need trailer parts I have ordered every thing from bearings and races to suspension bushings and spare tire covers from etrailer and have not been disappointed with any thing.
Very heavy duty steel and worked for my application. Sadly they are not galvanized; hence the 4 star rating. I prepped, primed, and painted them well so they should hold up. Used to hang fenders on a boat trailer.
SP01-160 U Bolts look to be good quality just wish they came with lock washers.
TRTP200175 U Bolt spring plates work well with these U Bolts. I ordered 4 of these and got 1 and 3 #117594 plates which are very nice and look more heavy duty.
I thought I got stiffed with the one oddball one but I didn't I ordered the cheaper ones and got 3 of the heaver duty ones.
I also ordered #LC281285 Never Fail Tandem Axle Suspension Hardware Kit and one bolt in the kit is to long like its for a 2" wide spring. Guess I will just use one of the old ones I took out.
And 4 #SP-051275 4 leaf double eye leaf springs.
I am redoing the suspension on a fiber splicing trailer that was damaged during hurricane Michael.
All in All etrailer has great prices and fast shipping and great customer service.
Had a leaf spring break on my off-road trailer in Mexico. Left it at a boat yard until I received the parts from trailer & returned to replace. Only took 2 hrs to replace both leafsprinhs, shackles, bolts etc. And we were back on the road.
The SP01-160 square u-bolts were perfect for my project. I had to have a certain size dia bolt and length, and these were just what I needed. I located some where I live, but they were very expensive. Found these at Etrailer and their price were half the price what they wanted here. I talked and ordered from Pat and she was very helpful on my order. The shipment was very fast also, ordered on Tuesday and received on Friday. I will definitely order from Etrailer again......Pat, thanks again

Worked out perfect very sayisified
These appear to be standard black steel and are of sufficient length to mount springs on top of axle or go with under slung arrangement. The nuts are crimped lock nut style which is ok.

No problems after one year of hard usage and heavy loads.
Always arrives quickly. I did add lock washers.
my friend ordered springs and hardware for my pontoon trailer. man did they get here fast. everything in one box. packed real good. no damage, nothing lost or left out. I finally got everything back together. fits great. i was worried that the springs where going to be to light, but the trailer sits just like new. sorry no pics. I was to greasy to get the camera out. But its like new again. yes etrailer.com i'm gonna be back next time I need parts. and i've already told all my friends with boats and trailers about etrailer.com . I am a happy customer. thanks again. C Finley

Well, these u-bolts are u-bolts. They're for my dual axle cargo trailer. They're 9/16" diameter. If you're familiar with these measurements and familiar with non commercial trailers, these are heavy duty hardware. And what I received, is what I expect. After carefully looking at what I needed and then looking at etrailer's website, I ordered these parts. They worked perfectly. I tightened them without reservation. They're holding. In my opinion, this took a little long to ship out to me, but otherwise, a good product.
Fixed my jet ski trailer without welding. I used this to bolt down all four supports that had begun to crack at the welds. I was concerned that welding would cause the galvanized steel to rust so I found this solution. The heavy construction of this part is very strong and should do the trick. Installation was very easy and quick.
U bolts are perfect. Set should have come with flat washers , or washer head nuts
Worked great fit was good.
I did not use standard nuts furnished but used Nylon lock nuts instead.

No problems....still like it and still going strong on my boat trailer!
Perfect fit with my other purchase and perfect for the repair job on my old trailer.
Great Experience!
When I noticed that the leaf springs on my 44 year old boat
trailer had cracked I thought I would never find replacements.
I fully expected to have to have something custom built.
I was amazed when I found the fantastic diagrams/descriptions
dimensions for replacement springs on etrailer.com
The phone support person was wonderfully helpful in confirming
if items were in stock and ready to ship. The replacement springs
arrived on time and everything bolted up perfectly!
Thanks for such a great site!
