Features to know about
Stronger Braking When You’re Loaded Heavy: One-Piece 13" Hub-and-Rotor for 7,000–8,000 lb Axles
When you’re towing at full capacity, you need brakes that stop straight and stay smooth. This Kodiak 13" hub-and-rotor assembly is built for 7,000- to 8,000-lb axles and uses a single cast-iron piece that’s factory balanced for steady rotation. The machined design keeps runout low and helps the rotor resist warping, so braking stays consistent under heavy loads.
Lasts Longer Around Water and Road Salt: Dacromet Coating with 300–400 Hour Salt-Spray Rating
Rust can eat through bare hubs fast, especially if you’re around saltwater or wet roads. This hub uses Dacromet plating tested for a 300–400 hour salt-spray rating. It gives tough corrosion protection without sacrificing the cast iron’s strong friction surface. That means less time fighting rust and more time rolling smooth in any condition.
Heat Stays Under Control on Long Grades: Vented Rotor Design Cools as You Tow
Brake fade from heat buildup can sneak up quick when you’re hauling down long runs or grades. The vented rotor channels air through the disc to dissipate heat before it builds up. Cooler operation protects the rotor surface and keeps braking power steady mile after mile.
Simplifies Installs and Retrofits: Factory-Balanced Unit with Races Pressed In
Swapping from drum to disc or replacing worn parts shouldn’t take all day. This one-piece hub-and-rotor comes with industry-standard races already pressed in and wheel studs installed. With fewer loose parts to manage, installation is straightforward whether you’re refitting or upgrading your setup.
Ready for Common Bearing Kits: Standard 25580 / 02475 Setup
You don’t have to chase odd bearing sizes—this hub uses standard 25580 inner and 02475 outer bearings with an RG06-070 seal (sold separately). That makes it easy to pair with common bearing kits like #DX38ER or find replacements down the line without special ordering.

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"

Quality is good. Delivery time fast. Jamie is well versed on the products.
Can’t say I’m happy about all the price increases across the board and definitely not happy with the suppliers creating such a shortage of parts we need for day to day operations.
Thankful that etrailer is doing their best to get us parts as quickly as possible.

See what our Experts say about this Kodiak Trailer Hubs and Drums
- 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... - Bearings and Seal for Replacing UFP Dexter 41062 Hub with Kodiak Hub and RotorI spoke with my contact at UFP Dexter and he said that your 41062 hub uses inner bearing 031-030-02, outer bearing 031-032-02, and seal 010-181-00. This is the equivalent of inner bearing # 25580, outer bearing # LM67048, and grease seal # GS-2125DL which can all be found in the bearing kit # BK3-310 along with the races for the bearings. Unfortunately the bearing kit # DBRKHW85G that you purchased isn't the same as the grease seal has a slightly larger diameter but that can easily be fixed....
view full answer... - Converting Triax 5th Wheel Trailer with 7k Dexter Axles to Disc BrakesWe have the Kodiak Disc Brake Kit part # K2HR712D which is the correct hub/rotor set for the 7k axles on your trailer. You'd need 3 of these for your trailer and then an electric over hydraulic actuator like the # HBA16 you mentioned. I would actually recommend the # HBA16-252-82 though as it comes with the breakaway kit plus enough lines for two of your axles. For the third axle you'd then want the part # 9579-01.
view full answer... - Grease Cap for Kodiak KHR1389D and Spindle for 2021 Forest River Riverstone 39RKFBHello Jonathan; the correct grease cap for the # KHR1389D is the Replacement Grease Cap for Kodiak 7,000-lb, 7,200-lb, and 8,000-lb Disc Brake Kits # KPCAP. The hub and rotor are designed for 7,000 - 8,000 lb axles. Our spindles only go up to 7,000 lbs so if you have an 8k axle we don't have one with a high enough rating. Otherwise you can use the #42 E-Z Lube Spindle w/ Flange for 5.2K to 7K Trailer Axles # TRU37FR. If you aren't sure, the capacity should be listed on the axle tag.
view full answer... - Replacement Hub/Rotor or Lippert 8K Axle with Kodiak 250 CaliperThe correct hub/rotor for your trailer is going to be dependent on finish and stud size. I have attached these options for you below which are for an 8,000 lb axle and will absolutely work with the Kodiak 250 Disc Brake Calipers like part # KDBC250D or part # KDBC250E. Dacromet - 5/8" Studs part # KHR13858D E-Coat - 5/8" Studs part # KHR13858E Raw Finish - 5/8" Studs part # KHR13858 Dacromet - 9/16" Studs part # KHR1389D E-Coat - 9/16" Studs part # KHR1389E If you pull the part number...
view full answer... - Replacement Bearings and Seal Recommendation for Kodiak Disc Brake Rotor/Hub on Keystone MontanaIf you have the Kodiak disc brake rotor/hub part # KHR1389D that you referenced the bearings you need are part # 25580 and # 02475 and then the grease seal is the part # RG06-070. If your trailer has 7k axles installed on it these part numbers would be what you'd need.
view full answer... - Replacement Rotors and Brake Pads for 7,000 lb Lippert Axle For your 2007 Teton Homes Experience, I recommend the Kodiak Disc Brake Kit - 13" Hub/Rotor - 8 on 6-1/2 - Dacromet - 7,000 lbs # K2HR712D for the entire disc brake kit. For just the hub assemblies with rotors, I recommend the Kodiak 13" Hub and Rotor - 8 on 6-1/2 - Dacromet - 9/16" Bolts # KHR1389D and bearing kit # BK3-200. For the brake pads, I recommend the Kodiak Ceramic Brake Pads - Stainless Steel Back # K250CP-SS or ceramic back # K250CP.
