Features to know about
Smooth, Consistent Braking Under Load: Precision-Machined 13" Hub and Rotor
This 13" Kodiak hub-and-rotor assembly is built for 7,000-lb axles, giving you solid braking performance even on heavy hauls. The one-piece cast iron construction is machined for accuracy to minimize runout and warping, so stops stay smooth and predictable. The vented rotor design sheds heat efficiently to prevent fade and damage during long or steep runs, keeping braking consistent mile after mile.
Strong Against Rust and Corrosion: Dacromet Finish With 300–400 Hour Salt-Spray Rating
Moisture and road salt can eat through unprotected metal fast. This hub’s Dacromet coating shields the machined cast iron from rust, tested to withstand 300–400 hours of salt-spray exposure. It’s a smart choice for trailers that see freshwater use or occasional saltwater contact, adding extra durability without the maintenance hassle.
Simpler Installs and Retrofits: One-Piece Balanced Assembly
Swapping from drum brakes or refreshing worn components is easier when everything fits as one unit. This single-piece hub-and-rotor comes balanced from the factory for a smooth ride, with industry-standard races already pressed in. That means fewer loose parts to juggle and a faster, cleaner installation—ideal for both upgrades and replacements.
Ready for Common Bearing Sizes: Standard Races Installed
The assembly includes the inner race (25520) and outer race (14276) already in place, designed to pair with standard bearings 25580 and 14125A (sold separately). It also works with seal RG06-070 (sold separately), which has a 2.250" inner diameter and 3.376" outer diameter. With its 8 on 6-1/2" bolt pattern and 1/2" wheel studs, it’s compatible with wheels 16" and larger—making it a dependable fit for a wide range of setups.

Determining Bolt Pattern
1. Count the lug holes
Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).
Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug
2a. For even lug counts (4-lug, 6-lug, 8-lug)
Measure from the center of one lug hole directly across to the center of the hole opposite it.
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"
2b. For odd lug counts (5-lug)
Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

For those who might be in my spot, I have a 1999 Triton TR19 with a 1999 Triton factory trailer (EZLoader?) with a 3500 lb UFP axle and original disk brakes. It had one original hub and one older replacement hub. Neither are still available and used different inner bearing races. Replacement bearings and rotor hubs that are direct replacements are basically no longer readily available. The KHR10D rotor hubs and BK2-100 bearing kit fit perfectly and had the parts I needed (I did not use the seals.) The original rotors were 10.25" but still fit well with the brake pads. I matched the rotors up with Bearing Buddy BB60002 seal kits to work with my spindles. Now both sides are the same and I know what I have. Hope this helps those with old trailers like mine.

- Replacement Bearings, Brake Pads, and Rotors for Dump Trailer With 7k AxlesHi Trevor; if you have 9/16" bolts you need the Kodiak 13" Hub and Rotor # KHR1389D with bearing kit # DX38ER. For 1/2" bolts you need the # KRH1378D with bearing kit # BK3-200. Both can use the Replacement Grease Cap # KPCAP. The replacement brake pads are the Kodiak Ceramic Brake Pads - 7,000 lbs to 8,000 lbs # K250CP or if you want the stainless steel back # K250CP-SS. What do you use your dump trailer for?
view full answer... - Does the Kodiak 13" Hub and Rotor KRH1378D Need to Be Cleaned Before Installation?No, it doesn't Richard. The Kodiak 13" Hub and Rotor item # KRH1378D doesn't come pregreased or coated with anything. What I do like to do for my own peace of mind though is take a clean towel and thoroughly wipe off the inside of the hub before you install the bearings. Once you get the Kodiak item # KRH1378D installed, I highly recommend cleaning off any bearing grease/oil and grime before you reinstall the calipers and pads. Do you use oil bath or a standard grease setup on your...

You may already know this, but what you have are the standard Kodiak 7K rated 8 lug hub and rotor assemblies. We have all of the parts you need, and I have listed those for you below. - Hub/Rotor Assembly # KRH1378D - Bearing Kit # DBRKHW7 - Cotter Pin # 165649 - Spindle Nut # 165686 The aforementioned bearing kit will include your seals and grease caps.

view full answer... - Replacement Rotor for a 2020 Keystone Montana 3121RLIf all you damaged was the rotor then you can just replace it with the Kodiak 13" Rotor item # KR1389D. I didn't get anywhere either with that serial number. However, it looks like your 2020 Keystone Montana 3121RL uses a inner bearing item # 25580 and an outer bearing item # 14125A. The Kodiak 13" Hub and Rotor item # KRH1378D you were looking at is exactly what you need to replace your gouged one if you want to swap out both the hub and rotor. For replacement brake pads you'll want...
view full answer... - Will the Kodiak 13" Hub and Rotor - 8 on 6-1/2 Work with OilThe Kodiak 13" Hub and Rotor part # KRH1378D can be used with either grease or oil, it all comes down to what seal and cap you pair it with since they are not incuded. If you're looking for oil, you'd just need the Kodiak XL ProLube Kit for for 5,200-lb to 6,000-lb Axles part # XLPROLUBE2440KIT.
view full answer... - Is There a Kodiak 13 Hub and Rotor - 8 on 6-1/2 - 1/2 Bolts - 7,000 lbs Thats ThreadedThe Kodiak 13" Hub and Rotor - 8 on 6-1/2 - 1/2" Bolts - 7,000 lbs part # KRH1378D that we offer are not threaded for an oil cap. That said, you can still use them with an oil cap that's pressed on, the Kodiak XL ProLube Kit for for 5,200-lb to 6,000-lb Axles part # XLPROLUBE2440KIT which also has the seals you need. The only hub/drum we have for this size axle that is threaded would be the Dexter 12-1/4" Hub-and-Rotor Assembly part # 008-416-91.

Thanks for sharing all the great information and the pictures. It definitely tough to match parts up on older trailers so your review will be helping a lot of people.
