Features to know about
Solid Hold for Heavy Axles: 1/2"-13 Galvanized Steel Construction
When you’re clamping down a 5,200-lb, 6,000-lb, or 7,000-lb axle, you need a U-bolt that won’t flex or corrode. This CE Smith replacement U-bolt is built from 1/2"-13 galvanized steel for lasting strength and rust resistance. At 6-11/16" long and 3-1/16" wide, it fits a 3" round axle and delivers the secure hold your suspension depends on.
Built to Beat the Elements: Hot-Dipped Zinc Coating Resists Corrosion
Saltwater, rain, and road grime can eat through plain metal fast. The galvanized finish on this U-bolt is hot-dipped in zinc with a coating roughly 3 to 5 mil thick, creating a tough barrier that keeps rust at bay season after season. It’s ideal for boat and snowmobile trailers that see wet or rough conditions.
Tight, Reliable Fit: Designed for 3" Round Axles
Getting the right fit matters for keeping everything aligned. This U-bolt’s round shape matches 3" round axles perfectly, holding them tight against the leaf springs when used with a U-bolt plate and a second U-bolt. The precise 3-1/16" inner width and 1/2"-13 thread ensure it tightens evenly and stays put under load.
Everything You Need for the Job: Nuts and Washers Included
No need to hunt down extra hardware. The U-bolt comes with matching nuts and washers, so you can mount your axle hardware right out of the box. It’s a straightforward replacement that restores secure suspension clamping and gets you back on the road with confidence.

Seems like a solid, well built piece. Time will tell after a few years of MA winter road salt & potholes. Fit a bit loose on a 3" axle, but once the nuts are tight there's no movement of course. At least the galvy will give it a fighting chance in the salt.

I called for assistance with ordering replacement leaf springs and shacklebolts for my trailer. Not being a mechanic I wasn't sure what to order. The wait for someone to take my call was a minute or two. Eli answered all my questions and guided me through which parts to order. He was extremely helpful and took my order over the phone. The parts fit perfectly but I determined that I needed to replace the u-bolts as well. So I called again and had the same experience with Naomi. My trailer is back together and ready for the road. But first I am having the brakes and wheel bearings serviced. I'll have the service technician check my work to be on the safe side. I highly recommend etrailer and suggest you call them to help order your parts.

- Torque Specs on a 2023 Grand Design Reflection 260RD w/ Curt 4,400 lbs AxlesHey Todd! We do not have anyway of knowing that information! You would need to check your owner's manual or reach out to Grand Design for specifications on torque.

- Correct U-Bolts For 3,500Lb Dexter Axle Every 3,500lb Dexter axle we sell has a diameter of 2-3/8" and typically uses a 5-1/2" U-bolt, such as U-Bolt Kit for Mounting 3,500-lb, Round Trailer Axles - 5-1/2" Long U-Bolts # APUBR-1. You may have a 5,200lb Dexter axle, which has the 3" diameter that you seem to have. With this, you would typically use U-Bolt Kit for Mounting 5,200-lb to 7,000-lb, Round Trailer Axles - 7" Long U-Bolts # APUBR-8, but these U-bolts are 7" long, which seem to be an issue in your situation.

- Roadmaster Comfort Ride Leaf Spring Suspension Kit For 2017 Open Range 297RLS 5TH Wheel CamperYou will want to use the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers # RM-2460-2560. This system is for axles and suspension rated up to 5,000lbs. Since you are not increasing your weight capacity these will give you the best ride quallity. The Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers # RM-2460-2570 having the heavier 7,000lb springs will create a rougher ride with the stiffer springs. I recommend having new U-Bolts w/ Nuts for...
view full answer... - Recommended U-Bolt Plates and U-Bolts For 7000lb Axles With 2 Wide SpringsI have another option for you, but the CE Smith U-Bolt Kit # CE23003 you were looking at is designed for 1-3/4" springs and will not fit with your 2" wide springs. Instead you will need two of the U-Bolt plate # TRTP300200 per axle, and two of the U-Bolts # CE15287GA for each axle. This will fit your 7000lb axles perfectly, and will be what you need to connect them to your leaf springs.
view full answer... - Does the Roadmaster Comfort Ride Leaf Spring Suspension Kit Fit a 33-1/2 Inch Axle Spread?Yes, it does. I checked with Roadmaster and the Comfort Ride Leaf Spring Suspension Kit item # RM-2460-2570 will work with your Luxury Lifestyle 5th wheels 33-1/2" axle spread. Your 7,000 lbs axles should be 3" diameter so this is definitely the kit you will need. The included slipper springs are 27" long. This will be a noticeable suspension upgrade for you. I have linked an installation video below. Since your current u-bolts are 7ish years old, I recommend using new u-bolts when...

It has an inner width of 3-1/16", a length of 6-11/16", and a bolt size of 1/2". I've linked to a video review of this u-bolt below.

If you scroll down and click on the weight range "5200 - 7000" you will then see u-bolt plates and u-bolts for that axle capacity, such as u-bolt # CE15287GA and u-bolt plate # CE20003G.

view full answer... - Replacement Suspension Parts for 18 Utility TrailerIf you have a serial number on your trailer axle or a plate or sticker on it that will list the VIN number, you can completely confirm your axle capacity but a 3" axle measurement would usually indicate a 5,200lbs or 6,000lbs axle. The Tandem-Axle Trailer Hanger Kit for Double Eye Springs # APT5 would be a sufficient capacity kit this application. For leaf springs, #PR4 is for a 4,000lb axle and maybe underrated. The 5-Leaf Double-Eye Spring for 6,000-lb Trailer Axles is also 25-1/4"...
