Grease cap fits trailer hubs with 2.446" inner diameter and has corrosion-resistant zinc plating.


After a lot of research with the help of etrailer support I purchased the Kodiak Disc Brake Kit K2HR712 and installed on a 2013 Dutchmen Rubicon 2900 with 7K lippert axles to replace the 13” Electric drum brakes. I discovered any questions about whether the disc hubs would fit my axle was eliminated when I realized I just had to verify the wheel bearing numbers for the disc hubs were the same as what was on my axles. (bearings, caps and seals do not come with the kit and need to be ordered separately).
My trailer had dual axles, the disc kits came in separate boxes that did fairly well in shipping, nothing poking out of the boxes or anything. Parts matched and fitted without any problems. Again, etrailer support was very helpful in getting the correct parts and any questions I had during the installation. I could have done this myself however I choose to have a brake tech do the hydraulic lines and bleed the system out. Very satisfied with the product and support.

Bearing caps worked fine and are still working. find and holding up shape great after being removed a couple of times.

Right item and on time.


Great quality, great prices. I converted an old gooseneck trailer from the open center mobile home-style hubs to modern 6k hubs on a budget. Was able to get all the missing pieces I needed from etrailer.


Great product at a great price.
issue was regular flat washer when D was ordered.
Will order my next project soon M/H to regular hub.

Everything still working fine.

I noticed that the original part had fallen off the trailer, and when I called to get the replacement parts, I was helped right away and the parts arrived within a couple days. the part fit well and has stayed on the trailer for over a year and many miles.


It fit perfectly. As instructed, I measured the hole with a micrometer and compared that to the stated size. WHAM perfecto! And the fine finish borders on an art form. As with my other engineering endeavors, I measured with a micrometer, marked it with chalk then installed it with a mallet. This installation increased the value of my trailer exponentially. The sheer number of compliments I get blows my mind. Thank you etrailer for making my life worth living.


Fast delivery. Good price. Exactly what I needed. Could not find at local auto parts.

I have used this product for a year and I it is still holding tight. Would buy another. If needed

Exactly what I needed after consulting with Sherry T. at She was awesome to work with and super knowledgeable. I recommend etrailer for any and all trailer needs! Thanks Sherry!


I decided to do some long needed maintenance on my old trailer and figured I would have a hard time finding parts, but etrailer had everything i needed. Fast shipping, too! I will be using etrailer for all my trailering needs.


after checking at every parts store around, finally found the right size grease cap for my trailer. THANKS perfect fit!


Received grease caps in excellent condition and in a timely manner. Caps fit perfectly. Caps are for the 38' boat trailer. Trailer rated for 30,000 lbs. Thank you.


Fit was perfect, selection was outstanding (I didn't even think about looking elsewhere). Delivery was fast. I have bought from etrailer before and no doubt will purchase from them again.


I use these products for a large fleet contract here at my shop. Professional product affordable price and excellent customer service. Shipping is rock solid and FAST.


Fits perfectly for my trailer, would buy again. Stays in unlike some products that fall out after a long haul.


i'm very happy with the dust caps ,, more so the fast deliver of the product !! thankyou


Product was a great fit for my old trailer and is a very good product.


This cap is made of very thin metal. Just tapping it in caused several big dents. Will have to be replaced with a "real" grease cap...!


Great product, great price, fast shipping and service! We'll do business again in the future!


One year in and still no problems and functioning great.


Very nice and shiny grease cap. It looks very art-deco.


The quality on these seems pretty good BUT they did not fit my axles and I sent them back for refund. Thank you


Great product. Fast shipping. And good communication of the product dimensions.


I mean what can you say about a bearing cap other then it fit.


everything worked great! Thank you ,great service.


Super fast delivery. Had to struggle a bit to get seated and bent the top a small bit but it does the job.

See what our Experts say about this TruRyde Trailer Bearings Races Seals Caps

  • Grease Cap for Dexter Axles With 2-3/8 Inch Outer Diameter
    The closest thing we have to a 2-3/8" outer diameter is the Grease Cap - 2.446" Outer Diameter - 1-5/16" Tall - Drive In # F001520. I recommend using a digital caliper like the # PTW80157 when measuring to ensure accuracy. If you find that it is in fact 2.375" then we do not have a grease cap available in that size. I'm not sure what you have now, but this has a crown height of 1.03" so you can compare to see if it is a lower profile.

  • 2.44 inch Diameter Dust Caps for Trailer Bearings on a Coromal Van
    We carry the TruRyde Grease Cap, # F001520, that should work for you, but you will need to make sure that the depth of the cap will work with the existing hubs on your Coromal Van. The depth of this cap is 1.03 inches, so as long as the spindle on your van does not protrude more than 1 inch beyond the face of the hub this grease cap will work for you.

  • Grease Cap Needed For Trailer Hub/Drum With Bearings Number 25580 Inner And Outer 15125
    In looking at kits for this bearing combination, there is a good chance you have a 2.446 inch outer diameter grease cap like # F001520. I recommend checking the inner diameter of your hub/drum where this cover sits to confirm size. A digital caliper like # PTW80157 is the best way to measure.

  • Grease Cap for Kodiak Disc Trailer Brake Kit # K2HR526D
    The recommended grease cap for disc brake kit # K2HR526D is 2.446 inch grease cap # F001520. So yes, a 2.44 would be the correct size if you already have some.

  • Diameter of Hole Where Grease Cap Sits on 6K Dexter Trailer Idler Hub With 6 on 6 Bolt Pattern
    The diameter of the pilot hole - where the grease cap will be - of the Dexter Trailer Idler Hub Assembly for 6,000-lb Axles - 6 on 6 - Agricultural # 42660UC1 is 2.446 inches. The correct grease cap to use with this hub is Grease Cap # F001520. This hub does not come with bearings, races, grease seal or cap so you will also need Bearing Kit # BK3-300. This kit has all the correct bearings, races and seal for this hub. I have added links to video reviews for you to check out as well.

  • Recommended Disc Brake Kit With 9/16 Inch Studs For 7,000-Lb Axle
    We do have a disc brake kit with 9/16-inch studs you asked about. I recommend the Kodiak Disc Brake Kit, part # K2HR79E. This kit has 13-inch hub/rotors and an 8 on 6-1/2 bolt pattern and is designed for 7,000 lb axles. The brake flange has a 5-bolt configuration. The inner and outer races are included but the bearings and seal are not so you will need part # BK3-200 that does include the bearings and seal. If you need new lug nuts for the brakes part # 6-53 is what you need. for a...

  • Will the Bearing Kit for Disc Brakes # DBRKHW6 Fit a Hayes T52 5,200 lb Axle
    To determine whether or not the Bearing Kit for Disc Brakes # DBRKHW6 will fit your Hayes T52 5,200 lb axle you will first need to pull a hub and locate the inner and outer bearing numbers as well as the number for your grease seal. The kit includes inner bearings # 25580 and outer bearings # 15123 with their races, grease seals # GS-2250DL, as well as drive-in grease caps # F001520 (with a 2.446" outer diameter), and 10 of our 1/2" trailer wheel lug nuts # CE11051.

  • Recommended Disc Brake Kit for Airstream Tandem Axle Trailer
    To convert to disc brakes, you will need to check the bearings on your current hubs. If you pull the hub you should find on the inner and outer bearing a number printed on each. Those numbers will help to confirm the fit on your spindle. If you can't find this number, then you can measure the spindle with a digital caliper like # PTW80157 where the bearings would rest on the spindle. I've attached a photo to assist. For 6 stud hubs with rotor, I recommend the Kodiak Disc Brake Kit...

  • Recommended Disc Brake Conversion for 7,000 lb Dexter Axles
    On your 2018 Montana 3791 RD, with Dexter 7K axles, we do have the parts but not in a kit for axles that large. I recommend the Kodiak Disc Brake Kit - 13" Hub/Rotor - 7,000 lbs # K2HR712D along with Bearing Kit # BK3-100. I recommend using grease # L11390 and cap # F001520 instead of doing the oil bath simply because if a seal fails you can melt your bearings and cause more issues than what grease would allow. Then for the electrical aspects, I recommend the HydraStar Electric-Hydraulic...

  • Recommended Electric Over Hydraulic Brake Set Up for 2016 Montana 3710FL 5th Wheel
    I was able to confirm that your Montana 3710FL uses tandem 7000 lb axles. A 7K axle would typically have an 8 on 6-1/2 wheel bolt pattern and the spindles would be compatible with a 25580 inner and an 14125A outer bearing. You'll want to identify the inner and outer wheel bearings used by your current hub/drums. Let me know if your hubs uses a different outer bearing. If your drums use the 25580 inner and 14125A outer bearing, I'd recommend the Kodiak 13 Inch Hub/Rotor Kit, part # K2HR712E....

  • Recommended Parts For Adding Disc Brakes To Tandem Trailer With 6,000-lb Axles
    We have all the parts you need but they do not alll come in one kit. I will make some recommendations that will work for your 6,000-lb axles. First, you can use the Kodiak Disc Brake Kit, part # K2HR526D. This includes the hub and rotors for one axle. You will also need a bearing kit, part # BK3-100 for each wheel. Since the lug nuts, part # CE11051 are not included, you can purchase them separately. For a grease cap you can use part # F001520. For a 24-ft long brake line kit that...
