Speaker 1: Today, we'll be having a look at the CE Smith line of U-bolt mounting kits for mounting round trailer axles. Here's what our kit comes with. It's everything you need for replacing the U-bolts on a single axle on your trailer. We have 4 new U-bolts, you'll have 2 per side; 2 new plates, 1 per side; 8 new lock washers, you'll be using 4 for each side of the trailer; and 8 new nuts, again 4 for each side of the trailer.You can see how well our U-bolts grip around the contours of our axle. This'll keep the axle firmly attached to our leaf springs, so we don't have to worry about it slipping and sliding.Now because we have the zinc and the galvanized finish on our plate and our hardware, this will better protect them from corrosion from the elements, especially salt spray. It's not an issue if you decide to use them on a boat trailer such as this one.Now many of our customers have had to make a second phone call or send an email to us after they bought a new axle for their trailer because they found, once they tried to remove the old one or put the new one on, that they couldn't get their factory U-bolts off.
They had to cut them off, and now they're searching for a replacement. This kit will be a perfect solution for this problem here.Now many of our customers compared these to the Redline line of U-bolt kits. Now the main difference you're going to see between this one and those is that those do not have the galvanized or the zinc finish on the plates or the hardware, which will cause them to rust out faster.As you can see, we already have our new axle sitting on top of our leaf springs. Now this kit could work for an axle that sits on top or below your leaf springs. It works for both applications.
You don't need to worry if yours resides below, you can still use this kit for that.We'll start by taking our new U-bolts and dropping them over our axle on either side of our leaf spring. Now we'll take our new plate. We want to make sure that this flange right here faces down, this hole here in the center lines up with the alignment pin on our leaf spring, and we'll insert our U-bolts through the holes. Place on our lock washers, and we'll put that on our nuts.Now we can start to tighten our hardware, making sure we tighten them evenly as possible. Now we'll torque our hardware again, making sure we alternate to ensure that we're doing it as evenly as possible.And that completes our look at the CE Smith line of U-bolt kits for mounting round trailer axles..

Fit as expected, the selection process was made easy
Had a hard time finding leaf spring mounting plate kit that had a 1 7/8" gap in the u-bolts. Ordered these and they fit perfectly and arrived in a timely manner. Shipping was as much as the item, but that is out of etrailer's hands of course. Quite happy with the product.
Extremely satisfied with etrailer.com! I Highly recommend this company!! I called to place an order at 7:00pm est and I talked with Roger R who made sure I ordered the correct leaf springs and hardware. I had purchased regular ground shipping but Roger and the entire etrailer crew that handled the order and packaged it up had it out the door and shipped that evening and I received the parts the next day which was over 600 miles away from their facility. I would have to say this was absolutely the best online purchase order experience that I have ever made, and I have made online purchases since online purchases were available. They have a great online catalog but if you call you will get professional and friendly service without question. I will use this company again and I suggest anyone that needs springs or guidance on installing them to give etrailer a call. They will have you the right parts shipped very quickly. I know to be as good as etrailer.com is takes the entire team and it starts with the person that answers the phone and then the person that processes the order and then the most important part when the person who packs it and gets it ready to ship does it to perfection. Thanks to Roger and the team I had my trailer rolling within 35 hours from when I called them.
U bolt kit and leaf spring kit fit great on the old 1979 snow mobile trailer
great quality parts, fast hipping and they were also cheaper than other online retailers; they should offer veterans and duty military a discount.
Was a perfect fit for my trailer. The original axle was rated for 1500 lbs, was very hard to find bearings for and took weeks to get. After the other side failed, I decided to upgrade to a 2000 lb axle that had common hubs and bearings. No regrets.
All items were as advertised and of good quality. Delivery was fast!
Great as ordered Amy and crew are on there game
I ordered my axle kit and received it 30 days later, I expected it in a week. The hubs, U-bolt kit, springs and grease were shipping in a box, when I receive it the heavy parts had smashed the grease tube, and was quite the mess in the box. The U-bolt kit I ordered as suggested by etrailer was the wrong kit and the bolts were short (their system did not suggest the right kit for the thicker springs). I see there is a kit I could have ordered with longer bolts. When I went to tighten the lug bolts on the new hub I received, one bolt started to pull through the hub. I reported the grease problem to etrailer, they could not care less, so I thought it would not be worth my time to report the other issues. I guess I will purchase new u-bolts, grease, and perhaps a hub somewhere else.
Springs fit perfect,trailer back togeth er.
Everything is great and Fred is great to work with
Everything arrived as expected and very promptly.
U bolts to short. Called customer service. They won’t have longer ones till august!
The u-bolts were not long enough.
Had to special order a different set of u- bolts.
Seems pretty tough so far!
Received my products exactly as ordered in a very timely manner. Quick changeover of axles as everything fit perfectly. There was very minor shipping damage that was easy to fix with a new grease fitting. Thank you.

Everything still 100 thanks to Etrailer!
The length of the U bolts was marginal and could be 1/4 of an inch longer so it is easier to install nuts w/o cross threading when using the lock washers.
Amazing customer service, thank you for everything.
Great fit on a 22 year old trailer!

Fantastic and trouble free 1 year later! Pull it 100 mile round trips with atv on it.
Everything fit on the trailer the 1st t ime.
no frills, no problems, nice and solid. It even survived a broken OEM spring incident on the road. I used it as part of a spring-over-axle conversion on my Aliner.

Hey you are welcome Mike! anytime! I will let Nicholas know you reached out.
Bought a motorcycle trailer from a local seller and needed a few parts for the axle. Purchased these from eTrailer and they worked great!
I've used eTrailer over the years as I'm just a DIY'er but they've always had excellent customer service and sell quality products. Great company and will continue to use them!
