Features to know about

Smooth, Steady Towing Under Load: 7,000-lb Axle with 94" Hub Face

A trailer that sways or bounces under weight can make towing stressful. This 7,000-lb axle keeps things steady with a 94" hub-face-to-hub-face length and a 79" spring-center spacing that’s built for balanced support. The 3" diameter axle beam is made from high-strength steel and includes welded spindles and spring seats for solid mounting. Its slight center bend creates a zero-camber angle that keeps the tires flat on the pavement, so the trailer tracks straight and smooth mile after mile.

Less Mess, Faster Setup: Pre-Greased Hubs and Easy Grease Spindles

Packing bearings can be a chore, but this axle comes with the work done. The cast iron hubs arrive pre-greased with bearings, races, seals, and lug nuts already installed. The Easy Grease spindles include built-in grease zerks, so future service is quick and clean—just connect your grease gun and keep rolling.

Confident Stops Every Time: Electric Brakes Included

Reliable braking is built in. The electric brake assemblies mount directly to the axle—no hydraulic lines or actuators needed. They include adjuster plugs and hardware for simple installation and can be manually adjusted as needed to maintain consistent brake feel and control while towing.

Durability You Can Count On: Certified and Tested Construction

Each component is engineered for long-term dependability. The hubs and drums are made from sturdy cast iron, and the patented welds on the spindles are 40% stronger to prevent failure under load. This axle meets CSA, QAI, and SAE-N certifications for safety and braking performance, proving it’s been tested to hold up on real roads.

Low, Easy-Loading Ride: Underslung Design for Leaf Springs

Loading cargo or equipment is simpler when the trailer sits right. The underslung layout has the spring seats welded to the underside of the axle, letting leaf springs (sold separately) mount below. It lowers the ride height for easier loading and a stable center of gravity while keeping everything solidly supported.

I didn’t think to clarify, I expected this to be shipped as one ready to install assembly. What I received was multiple shipment and not quite all the parts. Customer service quickly resolved the missing items and assembly and install wasn’t terribly difficult so I’m not knocking the product. It is what I was sold.



by:

Awesome axle the spring brackets where wrong from the description but moved and rewelded to fit with zero problems would definitely buy from this company again



by:

Awful service. Ordered an axle they sent a hitch. Cancelled order cause they weren’t going send axle out till they picked up the hitch lol. They still haven’t picked up and won’t refund money till ups picks up. Look around I found an axle place close by 30 minutes away with axles in stock. I will never use etrailer again!!!!!



by:

Delivered as described, earlier than expected, less costly than others with free shipping!
Careful measurements and the axle bolted right up.
Fully greased hubs with seals and bearings installed made assembly quick and easy.
Waiting on new tires for the trailer and will road test soon.
Couldn’t be happier with this purchase from Etrailer!



by:

The axle and spring seat are doing well after a year. Even with my shade-tree mechanic welding abilities and thousands of grueling miles thru some of the roughest highways in North America (namely West Virginia) both are holding up to the task.



by:

The axle and brakes were a perfect fit. All of the parts I needed were included and installation was straight forward. I could not be happier.



by:

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.

It’s GREAT!! Customer service is AMAZING!!



by:

Arrived on time and in good condition. The ends of the axel should be better protected. The delivery person dropped mine vertically on the asphalt. Fortunately, the crown nut took the blunt of the impact and the grease fitting wasn’t damaged.



by:

Best thing I did was change axles to these. Went from 3500lb to these 7000lb with brakes on both. Tows and stops incredible.

  • Comparing The Total Weight Of A Fully Loaded 6,000 lb Axle Versus a Loaded 8,000 lb Axle
    Hello Eric. We do offer a fully loaded 6,000 lb axle part # e73SR that weighs about 136 lbs including the axle, hubs and brakes. Now, we do not carry and 8,000 lb axles, but we do carry a 7,000 lb axle part # e23SR that has the same axle diameter as an 8K axle, and the fully loaded 7,000 lb axle weighs about 150 lbs. Since we do not have any 8K axles I can't give you an exact weight, but it stands to reason that a fully loaded 8K axle of the same length would be about 10-15 lbs more than...

  • What Wheel Stud Size do I Need for Your etrailer 7K Hubs?
    Hello Weston, For our etrailer Axle w/ Electric Brakes - Easy Grease - 8 on 6-1/2 Bolt Pattern - 94" Long - 7,000 lbs # e23SR you will want 1/2" Studs that are 1 1/2" like the Replacement Trailer Hub Wheel Stud, Drive-In, 1/2" x 1-1/2" (Qty 4) # RG03-020, or # 165981 for a single. What kind of trailer is this going on?

  • How to Find Replacement Hub for Homemade Tilt Trailer
    Hi Gary; measuring the diameter of the hub won't determine what fits your spindle/axle. You will have to identify your bearings to find the right replacement. They may be stamped into the bearings so start by checking there. If you can't find the part number, measure the inside diameter of the bearings or the spindle where the bearings ride using a digital caliper # PTW80157. See the diagram below. If you can provide me with this information I can see if a replacement is available.

  • Option For Replacing A Dexter 4,400 Lb Axle
    The big things we are looking for on the label are the weight capacity, hub face (HF) length, and the spring center (SC) distance. Your axle is a 4,400 lb 85" HF and 68-1/2" CS Dexter axle. I will tell you up front that we do not carry a direct replacement for this axle. The most similar option that we offer is the Dexter 5,200 lb axle # 8327816. This will be slightly longer than your axle at 86-1/2" HF and 71-1/2" SC. So while it may be a suitable replacement weight capacity wise, you...

  • Can Different Weight Capacity Axles 7K and 9K Be Used On a Tandem Axle Trailer?
    The biggest issue you may run into is going to be with replacing parts since you have different capacity axles. You are most likely going to have different brakes as well which may react differently and may notice one set of brakes wearing differently. Also you will need to ensure both the axles use the same weight capacity springs and you would be restricted to a maximum weight capacity of 14,000lbs since the axles share the load evenly.

  • How to Choose the Correct Axle Capacity for Trailer
    The axle capacity needs to be enough to handle the weight of the trailer plus whatever it is carrying. In other words, the axles need to meet or exceed the GVWR or gross vehicle weight rating. Assuming this is some kind of dump trailer with tandem axles I would say it weighs 2,000 lbs or more on its own. Add in the 9k lbs it can carry and you would be looking at 6k axles at a minimum, possibly 7k if the trailer is heavier. You will need to know the exact GVWR to select the right axle. For...

  • Parts Needed to Add Tandem 7K Axles to a Trailer From Scratch
    I do have some options for you but we don't carry dually axles nor do they offer these in a 7,000 lb weight capacity. The dually axles are typically between 10,000 - 15,000 lbs. If you're however okay with just tandem 7,000 lb axles then we may have an option for you, starting with the axle we have a few different choices depending on your trailer width. The Trailer Axle with Electric Brakes part # e23SR for example is 94" long whereas the Trailer Axle with Electric Brakes part # e83SR...

  • Recommended Timbren Axle-Less System For A 7,000 Pound Trailer
    Though we do not have an axle that is 68 inches at center to center we do have The Timbren Axle-Less Trailer Suspension System - Spindle w/ Brake Flange - Regular Tires - 7K # TASR7KS01.This system is rated for 7,000 pounds and has a bolt pattern of 8 on 6-1/2.

The system has a heavy-duty steel construction that has a black powder coat...

  • Info Needed to Determine if 7k Trailer Axle # #e23SR would Fit Trailer
    You can email me back with the picture of your axle but if what you have now is 94 inches long from hub face to hub face and has a distance of 79 inches between spring seats this # e23SR would work great as a replacement. Basically to pick out a replacement axle for you trailer you need the capacity and the two dimensions mentioned and you'd be set.

  • Heavy-Duty Axle Options From etrailer.com
    Thanks for reaching out! The heaviest axles we carry here at etrailer have a 7K weight rating (as of December 2022). Our standard axles have fixed hub-face and spring-center dimensions but we also carry the Timbren Axle-Less System # TASR7KS01 that installs directly to the trailer frame so it can fit virtually any spring-center dimension since it uses it's own suspension system. I've attached a few videos of the Timbren system as well as a link to our selection of 7K axles and a video...

  • Spring Seat for 7k Trailer Axle w/ Electric Brakes # e23SR for Underslung Axle
    We only have the 7k Trailer Axle w/ Electric Brakes # e23SR in an underslung configuration so what you can do is install a different set of spring seats on the opposite side of the axle like with # TRSS300.
