A loose axle can throw off your whole suspension. This kit uses four 3/8"-diameter, 4-1/4" long U-bolts that clamp your 1-3/4" round, 2,000-lb axle firmly to the leaf springs. The thick steel holds its shape under load, keeping the axle locked in alignment so the trailer tracks straight and rides smooth.
Getting hardware that actually matches your setup saves a lot of frustration. This kit includes two U-bolt plates sized for 1-3/4" wide springs and eight 3/8"-24 hex nuts. Everything lines up cleanly so you can bolt the axle and springs together without having to hunt for extra pieces.
Designed for 1-3/4" diameter round axles—common on 2,000-lb systems—this hardware hits the sweet spot for light utility, camper, or car hauler trailers. The dimensions are tuned for these smaller axles so you get a snug fit without over-torquing or bending the brackets.
You don’t need anything fancy to get this done—just tighten the 3/8" nuts to the proper range of 30-50 ft-lbs for a secure hold. Once torqued down, the plates and U-bolts keep the suspension solid mile after mile. Spring seats for mounting the axle to the leaf springs are sold separately, so you can weld them exactly where you need them.

Randy: Hey guys, it's Randy here at etrailer.com. Today, we're going to be taking a look at a replacement U-bolt kit. This is going to be designed for the 2000 pound axles, looking for an inch and three-quarter axle diameter. You can see how they're designed to fit around your axle with an incorporated plate here and hold that axle to your spring pack.Now, I think it's crucial anytime you replace an axle that you replace these U-bolts. Over time, of course, they're going to get stressed and they're going to get strained. They can even stretch out on you.
And basically by getting a new set, not only do we have new hardware, so we don't have to worry about any cross-threaded situations, we get new lock washers and a new plate down here, by getting these new U-bolts, you can rest assured that your axle is going to be held securely to your spring.When we just throw our old U-bolt kit back on there and we start torquing it down, there's no way for us to know for sure that it's actually holding to the values that we want. So definitely keep that in mind. I think that anytime I replace an axle, I always get a new U-bolt kit for it. Talk to our customer, explain to them the benefit and let them know that by replacing that you get that peace of mind and you know that you're not going to have any issues with it down the road. And oftentimes it's hard to get the old nuts off.
They're usually rusted onto the U-bolts and you generally have to wind up cutting them. So in my mind, if you're ordering an axle, definitely get a replacement U-bolt kit. So when you do get everything there, you're not running around trying to find it. It's a very cost-effective way to freshen everything up and get it ready to go.Now, when we install our U-bolt kit, essentially we'll take two of the U-bolts and they need to go around our axle. In our case, our axle's sitting on top of the spring so we put the spring perch right on the bolt that sticks out, because that's going to be sitting right in there, right in the middle.
Then our plate needs to go on the opposite side of that. And if we look down low, you'll see that bolt's also going to come through the center hole on that. The two outside holes, we've got our U-bolts that come down through. Then we're going to place a lock washer and we're going to place a nut on each one. Once we've got that done, we need to equally tighten these down to get them nice and snug.
Then we'll torque them to specifications. Now we'll just head over to the other side and repeat that same process there. We'll be ready to go..

No problems with this or the other parts I used to convert to spring over configuration. I recommend etrailer and will use them next time I change my rig.

The upgrade from 8 to 10 inch wheels made a huge difference in how my trailer tracks. It used to swing side to side at 70, no longer!The mounting plates replaced a broken plate and I very pleased with the quality of the hardware. I also relocated the axle to below the spring to account for the larger wheels.You guys have always been great, always my first choice for trailer parts and accessories.
