Features to know about

Smooth, Controlled Towing: 5,200-lb Electric Brake Axle Handles the Load

A stable ride starts with a solid axle. This 95" long trailer axle with electric brakes is rated for 5,200 lbs, giving you the strength needed for steady, controlled towing. The round, 3"-diameter high-strength steel beam has a built-in camber that keeps tire contact even across the tread for smooth tracking and dependable road handling. Electric brakes are already installed, so you get firm, responsive stopping without hydraulic lines or actuators.

Less Maintenance and Mess: Easy Grease Spindles and Pre-Greased Hubs

Keeping bearings in good shape doesn’t have to be a chore. The straight spindles on this axle feature built-in grease zerks that make lubrication quick and clean. Each hub comes pre-greased with bearings, races, seals, and lug nuts already in place, cutting down on setup time and keeping your hands cleaner. When it’s time for service, just connect a grease gun to the zerk and you’re done.

Built Low for Easier Loading: Underslung Design with Welded Spring Seats

Getting cargo on and off the trailer is easier when the deck sits lower. The underslung layout has spring seats welded to the underside of the axle so your leaf springs mount below. That setup drops the trailer height for simpler loading and unloading while maintaining a sturdy, balanced stance. The 80" spring-center spacing is pre-welded and ready to bolt up.

Reliable Hardware and Strong Construction: Certified for Safety

Every component is built for strength and tested for safety. The cast-iron hubs and drums measure 12-15/16" diameter x 2-3/8" wide and fit a 6 on 5-1/2" bolt pattern with 1/2"-diameter wheel studs. It’s CSA, QAI, and SAE-N certified to meet performance standards for braking and durability. Each weld is reinforced with a patented process that’s 40% stronger to prevent spindle failure, so the axle stays dependable mile after mile.

Ready to Replace or Upgrade: All Key Parts Included

This axle arrives with the critical components you need to get rolling—electric brake assemblies, hubs, drums, bearings, races, seals, grease caps, and lug nuts. With 95" hub-face and 80" spring-center measurements, it’s an easy way to replace a worn-out axle or step up to a stronger 5,200-lb setup that’s built to last.

I ordered two axles to upgrade my trailer capacity to what the frame is rated for, 12,000lbs. The axles have great bearing seats and backing plate studs. The backing plates are fully assembled and ready to connect to the wires already installed into the axle tubes. The hub assembly went smooth and only one set of break shoes needed adjustment. A good buy along with the 5 fully assembled tires and wheels.



by:

Buying the kit complete was a good decision. It showed up early than predicted and having the grease and wires already in place shows your professionalism. I would recommend this product and company to everyone in the market.

Excellent Axles



by:

I replaced the old axles on my trailer. I found these to be excellent quality. The install was not bad. I've taken a couple of long trips maybe 1000 miles one way and loaded. These axles head up perfectly.



by:

I shopped around and found etrailer had the best deal for an axle i needed. My old axle was not an ez lube but the etrailer offering was so that was a great improvement for maintaining the axle!



by:

Had it in 3 days fast!!

Fit perfect easy install

Picture shows complete axle assembly. Received three boxes and an axle with smashed threads



by:

Went together well, perfect replacement. Be sure to measure from spring centers (80" on the nose) and hub faces (95" on the nose). I was suprised when this shipped UPS. I didn't know they would handle something this large/heavy. 3 boxes and the axle. One box has the electric brakes. One box each for the hubs (pregreased). Came with castle nuts, washers and cotter pins and nylocks for the ebrakes. One end of axle was just wraped in plastic and plastic was ripped around circumference of spundle end but threads and zirk were intact. On the other end of the axle it was protected with a rubber boot under the plastic wrap and threads were ok but zirk had been snapped off. Used an easy-out to extract the rest of the zirk out of the axle and replaced with a new one. Zirks are 1/4" - 28tpi. I have no idea what the manufacturer of my trailer is other than Joe Schmoe farmer LOL. But it has two 6 bolt hub axles made in china just like this one and the measurements matched. On one axle the brakes failed, then bearing failed, then hub and wheel sailed off and there was too much damage to the spindle and threads. The spindle can be replaced but chose to get this axle for quick and easy turn around. I then shot both hubs full of grease with an air operated grease gun which took about two tubes of grease. The bearings come prepacked with the blue marine synthetic grease, I shot the hubs with red GLCI 2 once hubs were mounted on the axle and grease cups mounted. Their are two grease cups for each hub, one with removable rubber center disk and one without - you choose. Other related info: Spring bolts were 9/16"-18tpi x 3", I had to snap two off so replaced all four for this axle with grade 5 bolts and nuts and used split ring lock washers. Shackles I bought from here did not come with lock washers so I put 1/2" split ring lock washers under the shackle nuts. Extra hardware all came from McMaster Carr. I did cheat and used a tractor with bucket mounted hitch to lift and lower the trailer tongue :). It was more of a pain to remove the old axle than install this new one, took a couple hours, I am in my 60's. So not bad at all. I have not used the trailer with this new front axle as yet but I have no qualms about doing so. I have noticed the front of dual axles always seems to take a disproportionate more amount of the load no matter what the tongue height or accurate the tire pressure. Just as good an axle as the original.

  • Is There a Replacement Spindle For a Dexter D44, 4400LB Trailer Axle?
    My recommendation is to replace your axle with a 5,200lb like # e55SR as the 4,400lb spindle is so uncommon they are not readily available. This will give you stronger components to lessen the chance of you having to replace a spindle in the future. If you can provide me with the dimensions for your axle I can verify the correct replacement for your D44 axle. The #84 E-Z Lube Spindle # TRU74FR while similar has a narrower diameter of 1-1/16" for the outer bearing where a 4,400lb uses...

  • Replacement Axle, Hubs, Brakes, and Tires for Older Trailer With Dexter 22834 Hub
    Based on the axle and bearing measurements it looks like your trailer was using a Dexter 22834 hub. The Outer Bearing # 1779 has an ID of .938" and the Inner Bearing # 2788 has an ID of 1.50". The outer bearing is slightly off but that may be due to a measuring error. That would also mean you have 5,200 lb axles on the trailer. This is an obsolete assembly so you will need to replace the entire axle. For a replacement you can use the # e55SR. This will stick out an extra 3/4" on either...

  • Recommended Replacement Axle for a LCI 3.5k Axle
    Benton, the closest replacement axle we have is the Trailer Axle w/ Electric Brakes # e55SR. This axle has a 95" hub face to hub face measurement, has a 5.2k capacity, and includes the electric brake assemblies, hubs, drums, bearings, races, seals, and mounting hardware. As you mentioned, the spring seats will need to be re-welded in their correct spots, otherwise this will work as a great replacement.

  • What Could Cause Just One Tire To Wear On The Inside Edge?
    Hey Rickey, any chance that tire is under/over inflated? That is something that could cause it to wear unevenly compared to other tires. Typically when we see tires wearing on the inside edge only it is because the trailer is overloaded. Although you would usually see these signs on more than one tire. If the trailer is not overloaded, the suspension is aligned properly, and the tire pressure is ok, it could be a bent axle or spindle which would generally be caused by an impact.

  • Looking for Replacement Dexter Axle 184357
    Hey Doug, I looked up your axle part number and was able to determine that it is a 5,200 lb axle with brakes and a 6 lug bolt pattern but I was not able to find the overall length of the axle from hub face to hub face as well as the spring seat to spring seat dimension so I would need you to get me that info so we can see if we have the axle you need. In the meantime I attached a link to a page that has all of the 5,200 lb trailer axles we offer.

  • Need Replacement Axle for LCI 4400 LB axle that says 95.5/75
    Hey Charles! For your 2012 Work and Play WPT21UL, that “95.5 / 75” on the LCI 4,400-lb tag means 95.5" hub-face and 75" spring-center. You won’t see that exact axle everywhere, but upgrading to a 5,200-lb axle is a solid path. The common close match is 95" hub-face / 80" spring-center, and you can simply have a local trailer or welding shop move the spring seats to 75" to match your frame, that’s a pretty routine job. A ½" difference in hub-face (95.5" vs. 95") only shifts the wheels about...

  • How To Upgrade Hudson 10,000LB Trailer From Mobile Home Wheels & Tires To Standard Wheels & Tires
    To switch your 10,000lb Hudson trailer to use more standard wheels and tires you will need to replace your axles. The spindle size used on your current axles is only going to allow for the Mobile Home style wheels and tires since the hub is specific to these axles. You will need to measure your axle from hub face to hub face to determine the correct width axle you will need. Here is a list of 5,200lb axle which include electric brakes and have a 6 on 5-1/2" bolt pattern. If these do not...

  • What is Needed to Upgrade From 3,500 lb to 5,200 lb Axle
    From what I can see your Keystone trailer has a pair of 3,500 lb axles so to upgrade to 5,200 lb axles you'd need the axles, U-bolts, and hubs. In order to choose the correct replacement axle for your trailer you will need to know the dimensions of your current axle's hub face to hub face and spring center to spring center; I have added a link below to a video which walks you through how to measure. For example, the 5,200 lb Trailer Axle w/ Electric Brakes # e55SR measures 95 inches from...

  • Can Axle Weight Rating be Increased with Upgraded Leaf Springs and Hubs
    To upgrade your axles to a 5,200 lb weight rating you'll have to swap out your 3,500 lb axles for 5,200 lb axles like part # e55SR that comes with electric brakes and has 95" hub-face and 80" spring-center measurements. Unfortunately you have to upgrade everything to get the higher weight rating as the axle tube itself will need to be stronger. And even after you upgrade the axles it doesn't necessarily mean your trailer can handle more as the trailer frame is also a factor when it comes...
