I’m pleased with the kit. I think it would be great if it came with a new hub nut in the kit though!

by: Mark 11/23/2019

Received all that I ordered and installed without issues. However I did have to get a race installer for the inside bearing race as the kit purchased was not for that size. I wish someone from etrailer would have called to double check if those were the correct ones I needed.

No issues, so far product has held up. Have only aproximately 5K miles on new bearings. Will be taking apart in 2021 to inspect brakes as well as the bearings

by: Troy 08/01/2025

What can I say? It’s a bearing kit. All parts were there and in perfect condition. I did however order the wrong size so they will be going back.

Great with no problems

by: J. Don 07/13/2018

Very good transaction all round. The description given in their ad matched our faint numbers perfectly. Every bearings and accessory items in the kit fit our 7,000 lb. axles. Thanks to a very much appreciated upgrade; delivery was almost instantaneous. Communication was more than outstanding. All we can be critical of would be not being able to pay with PayPal.

I will admit to checking [another website] first for this bearing kit. For everything, minus the cotter pin and nut holder, the price was double and needed to be ordered separately from different vendors. The only difference was shipping speed. The etrailer site, customer service and product quality is way above everyone else I've dealt with. I guess I just need to remind myself of that every once in a while. These bearings, races and accessories are heavy duty and appear to be of excellent quality. No issues with fitment.

by: Mark 04/17/2023

I placed an order for wheel betting’s for my trailer. In doing so, it appeared the order did not go through, so I placed it again. After a bit I got notified both orders went through. I immediately went back to Manage my order and cancel the second order. Thinking all was good, but checking my phone a couple hours later I found an email to confirm my cancellation which was only active gor 20 minutes. I tried to confirm then but could not and both orders were shipped. I call customer service and they said I had to pay $xx to return ship the 2nd order!! I buy numerous items from trailer and believe your policy after cancellation to then confirm is wrong! Believe me this will be my last order with Etrailer! Plenty of other places to buy the products I need for my trailer!!!!

After 1000s of miles on the bearings, everything is great! Thanks for reaching out to me.

by: Dan G. 06/19/2017

Have ordered from etrailer before and everything was as expected. This is the first time ordering seals & bearings from etrailer. The BK3-210 bearing kits arrived promptly and appear to be in good condition. I ordered this kit for use as spare parts in case of a bearing failure while on the road. I was surprised that the seals and particularly the bearings were not in individually wrapped and sealed packaging; simply packed together in the shipping box. I don't recall ever purchasing bearings or seals that were not wrapped & sealed individually.
etrailer offers great prices and quick delivery, I'm just not particularly comfortable with the lack of individual packaging of these seals & bearings.

by: Jerry 10/03/2013

Once we found the correct seal everything went well. Fast delivery and correct parts. I don't understand what the washer with the tab on it is? I would order from you again and would also recommend you to others.

Patrick B.

It is a tang washer for EZ-Lube spindles. It is used in place of the cotter pin to keep the castle nut from backing off.

Firebear

10/19/2015

The washer with the tab is one option for locking the castle nut. Once the nut is tight, you would pry up the tab and flatten it against one flat of the nut.

Bearings and Races for 7,000 Pound Trailer Axle
The most common bearings and seals for a 7,000 pound axle are # 25580 inner bearing, # 14125A outer bearing, # 25520 inner race and # 14276 outer race. The grease seal can vary, and will usually either be the # GS-2250DL, which has a 2.250 inch inner diameter and 3.376 outer diameter, or # GS2125DL with a 2.125 inch inner diameter and 3.376 inch outer diameter. We do also offer complete bearing kits for this axle. For the GS-2250DL grease seal, you can use the Kit # BK3-200. For the #...

Need Wheel Bearing Kit For Dexter 7,000 lb Axle
Hey Ethan, thanks for reaching out. The correct bearing and seal kit for your Dexter 7,000 lb axles is going to be either the Bearing Kit part # BK3-210 which has a 2.125" seal or the Bearing Kit part # BK3-200 which has a 2.250" seal. This axle could have come with either size, so I suggest you pull a hub and measure the spindle where the seal rides, or just pull a seal and measure it to confirm. The other option is to just get one bearing kit and order the other seal; 2.250" part #...

Looking for Bearing Kit that Fits MORryde 7k Trailer Axle
Hey Randy, so one of the great trailer replacement part mysteries is what grease seal a 7k trailer axle will use. Sometimes it's one with a 2.25 inner diameter and sometimes it's 2.125 inch. It seems like the most common for a 7k is the 2.125 inch but without any rhyme or reason that we have found it can be either. The # BK3-210 that you referenced comes with a seal that is 2.125 inch in inner diameter. What seal are you in need of?

Looking for Bearing Kit for 2023 Big Tex Equipment Trailer
Hey Hoss, do you happen to know the axle capacities on your trailer? I'd imagine what you have is either a 6k or 7k axle setup but it's always a good idea to verify. If you do have a 6k axle the correct bearing kit would be the part # BK3-210 or 7k part # BK3-200.

Hey, Mike! Dexter shows that the 130123 axle is a 7k axle so would be using seal part # RG06-070. We offer complete kits that come with new seals, bearings, and races as well. That's kit part # BK3-210. Are you doing some maintenance on your trailer?

Adding Brakes to 1999 Jayco Heritage Glacier with Dexter 2,500 lb Axles
A Dexter 2,500 lb axle uses hubs that have inner and outer bearings of L44649 like the part # 8-257-5UC3 which has a 5 lug bolt pattern or the # 8-173-16UC3-EZ which has a 4 lug bolt pattern. These both come with bearings and seals as well. For brake assemblies you'd want the part # 23-47 for the left hand side and # 23-48 for the right hand side and you'd be set. I attached a help article link on adding electric brakes to a trailer for you to check out as well that I think you'll find...

Which Bearing Kit With Seal Is Correct Fit For Dexter 651773 7K Axle ?
Hey Mike! Your 7K Dexter axle 651773 will very likely use Bearing Kit # BK3-200, which has a 2.250" inner diameter grease seal. However, some 7K Dexter axles use # BK3-210 instead, which has a 2.125" grease seal. When you pull everything apart, check the numbers stamped on the existing grease seal or measure the Inside Diameter. That will be the best way to confirm which kit you need: Bearing Kit # BK3-200 – 2.250" grease seal ID Bearing Kit # BK3-210 – 2.125" grease seal ID The bearings...

Wheel Bearing Kit for 2021 Keystone Fuzion 373
Hey Ruben, welcome back! For your 2021 Keystone Fuzion 373 with 7,000 lb axles, the Bearing Kit # BK3-200 you were looking at is likely what you need. This includes the inner and outer bearings, races, and a 2.25" ID grease seal. You'll need one kit per hub, so four total. However, some 7K axles use a smaller 2.125" seal, which would require the Bearing Kit # BK3-210 instead. If you can send me the serial number from your axle tag, or just send a picture of it, I can verify which seal...

Replacement Bearing Kit Recommendations for a 1972 Airstream Overlander

Can You Use 8,000 Lb Wheel Bearings on a 7,000 Lb Trailer Axle
The wheel bearings for a 7,000 lb axle are not exactly the same as the wheel bearings for a 8,000 lb axle, the inner bearings are the same but the outer bearings are not, they have different outside diameters. Therefore, the two are not interchangeable. That said, even if you could upgrade this would not increase capacity nor should it really give you any more peace of mind. The weight capacity comes mainly from the axle beam and spindles. If you need replacements for your wheel bearings,...

What Grease Seals do I need If I have a 14136a Bearing With a 14276 Race
Hey, Jeremy! I’d be happy to help! After doing some research, it looks like the 14136A bearing is typically used for industrial equipment. The trailer equivalent would be # 14125A, which uses the same race # 14276 you mentioned. All of the bearing kits we carry that include that bearing come with grease seal # RG06-070. I’m not sure what your exact measurements are, but this seal has a 2.250" inner diameter and a 3.376" outer diameter. If you’d rather get a complete kit instead of just...

What Bearing Kit do I Need for My 2024 Montana High Country 295rl with 7,000 Pound Axles?
Hello Josh, Thanks for all the information, it is most helpful. I am showing that you have a #42 spindle. The # BK3-210 kit you were looking at was almost the right kit, the grease seal is the only thing that is not correct. You need one with a 2.25" I.D., so you will need the Bearing Kit, 14125A/ 25580 Bearings, 10-36 Seal # BK3-200 for your 2024 Montana High Country 295rl. If you don't have some grease on hand, make sure you grab some LubriMatic Prime Guard High Temperature Wheel Bearing...

Hey Ryan, thanks for the information. We have two different bearing kits for Dexter 7,000 lbs axles. Item # BK3-210 and item # BK3-200 which has a a slightly larger grease seal. The bearings and races are the same size in both kits. Each kit will replace one hubs bearings, races, and seals. What you'll need to do is measure your spindle where the grease seal rides for it's inner diameter. That spot is labeled B on the diagram below. If it's 2.125" you need item # BK3-210.

Hey Cameron, the most common bearings on 7k axles are inner bearing # 25580 and outer bearing # 14125A.
