Features to know about

Built for Heavy Loads and Strong Braking: 8,000-lb E-Z Lube Axle Fit

When you’re towing with serious weight, you want a hub and drum that can handle it. This Dexter assembly is designed for 8,000-lb E-Z Lube trailer axles with #42 spindles, giving you a solid match for heavy-duty setups. The hub-and-drum provides the braking surface for 12-1/4" x 3-3/8" electric or hydraulic brake assemblies, delivering dependable stopping power when you need it most.

Smooth, Low-Mess Greasing: E-Z Lube Access Design

Keeping bearings greased is usually a messy job, but this hub’s E-Z Lube setup makes it quick and clean. Just remove the rubber plug from the grease cap (sold separately) and add grease through the zerk fitting on the spindle—no need to take the hub apart. It’s a straightforward way to keep everything turning smoothly mile after mile.

Precision Fit for Reliable Performance: Races Installed and Ready

The inner and outer races come pre-installed, so you’ve got the key precision parts already in place. Pair it with the correct bearings—inner bearing 25580 (1.750" inner diameter) and outer bearing 02475 (1.25" inner diameter)—and grease seal 10-36 (2.250" inner diameter, 3.376" outer diameter), and you’re set for a secure, accurate fit that keeps your wheels running true.

Sturdy Iron Construction: Built to Last Under Load

The iron construction gives this hub-and-drum the strength to handle demanding use without flexing or cracking under pressure. Each unit carries a 4,000-lb capacity, providing dependable support across tandem or multi-axle setups. It’s built for long-term durability you can count on every trip.

Standard 8-on-6-1/2 Bolt Pattern: Easy Wheel Compatibility

With its 8-on-6-1/2" bolt pattern and 9/16" wheel studs, this hub connects easily with standard heavy-duty trailer wheels in 16", 16-1/2", 17", and 17-1/2" sizes. The 4-3/4" pilot hole centers your wheel securely, giving you a balanced ride and confident braking performance on the road.

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.

Center to Center
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).

Center to Outside Edge
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Took way too long to ship from the warehouse. Tracking info was not specific and told me two different dates at the same time. I emailed you early in the order procesd and you never replied. I would assume that many of your customers are contractors and need parts in a timely manner. By delaying the shipping, you are delaying someones job. The parts came in dirty. I will not be ordering from you again.

  • 2015 Palomino Sabre 36QBOK Brakes and Bearing Recommendation
    I looked in several places online and couldn't get a definite axle capacity for your trailer. I'd assume it's a pretty high capacity since it's a tandem axle trailer that weighs 12k and has 3k of capacity. So most likely you have 8k axles like what the part # 8-285-11 hub fits which has bearing numbers # 25580 and # 02475 with grease seal # RG06-070. Then for brake assemblies part # AKEBRK-8. Get me the diameter of your axles though and I'll be able to get you a better recommendation. Typical...

  • Comparing Dexter Hub and Drum Assemblies 8-285-11 and 8-393-4UC3
    You will experience some reduced braking power when using the Dexter Trailer Hub and Drum Assembly # 8-393-4UC3 with 12-1/4 x 2-1/2" brake assemblies compared to the # 8-285-11 with 12-1/4" x 3-3/8" brake assemblies. Between the two I recommend going with the # 8-285-11 along with bearings # 25580 and # 02475, grease seals # RG06-070, lug nuts # 6-53, and grease caps # rg04-120. For brakes I recommend the self adjusting braking assemblies # 23-434-435. Since you mentioned your axle does...

  • Meaning of 8 on 6-1/2 Inch Bolt Pattern for Dexter Hub # 8-285-11
    The 8 on 6-1/2 inch description that you see for the Dexter Trailer Hub # 8-285-11 refers to its bolt pattern. It is important to note this feature when replacing your hubs because it needs to match the pattern on your existing wheels for the wheels to mount properly. If you are unsure what bolt pattern is on your current hubs or wheels you will just need to take a quick measurement to determine this. For a wheel or hub with 8 bolts, you will simply measure from the center of one bole...

The electric brake drum assembly that fits the 8-285 hub and integrated drum would be the Dexter Electric Brake Assembly-Left Hand, part # 23-434, for the left side and Dexter Electric Brake Assembly-Right Hand, part # 23-435.

    As long as you are not going over the 2,000 lb capacity then the Timbren Axle-Less Trailer Suspension System # ASR2000S02 will work well. You will need one like this that has the brake flange attached in order to use brakes. For a compatible hub and drum assembly, I recommend the # AKHD-545-35-EZ-K. This uses a 5 on 4-1/2 bolt pattern so you will want wheels that match the bolt pattern. For brake assemblies, I would choose self adjusting brakes like the Dexter Nev-R-Adjust Electric Trailer...

  • Grease Cap for Dexter 8-285 Trailer Hub
    An 8-285 hub does not have the correct bearings or races to work with Bearing Buddies, so you would need to use a standard grease cap. For example, the # 8-285-11 hub and drum needs Trailer Hub Grease Cap # TRU66FR for a quantity of one or # RG04-120 for a quantity of two.

    The 008-285-11 number you found on your existing Dexter hub does refer to the Dexter Trailer Hub and Drum # 8-285-11, however as you mentioned, this particular assembly uses 9/16 inch wheel studs. This is the case with all of our grease lubed hub and drum assemblies that are designed for 8,000 pound axles. We do have the Redline Trailer Hub and Drum Assembly # 8-285-10UC3-A, which will work as a replacement on your axle. This is an oil bath hub and drum that uses the same # 25580 inner...

  • Is The Distance Between Races On Dexter Hub 8-285-11 and 8-393-6UC3-A The Same?
    I had our warehouse measure the distance between the inner and outer races of the Dexter Trailer Hub and Drum # 8-285-11 and # 8-393-6UC3-A and they found that both of them have the exact same 1-3/4" measurement, so as long as you have the # 25580 inner bearing and # 02475 outer bearing combination either hub will fit fine. You will just need to match the hub to the correct brake assemblies as the # 8-285-11 uses 12-1/4" x 3-3/8" brake assemblies # 23-434-435 where the # 8-393-6UC3-A uses...

  • Are 8k Dexter Trailer Hubs a Fit for Both Sides of the Trailer
    Trailer hubs are not directional like brake assemblies are. The number you mentioned is very similar to the # 8-285-11 which is a fit for both the right and left side of the trailer. The electric brake drum assembly that fits the 8-285 hub and integrated drum would be the Dexter Electric Brake Assembly-Left Hand, part # 23-434, for the left side and Dexter Electric Brake Assembly-Right Hand, part # 23-435.

  • Is it Necessary to Grease the Hubs on a G-45 Tipper
    If is has wheels and bearings then it's going to need grease (or oil if it is an oil bath hub). I have included a link to a video that shows how to pack bearings with grease by hand. We also have a tool that can be used, # L70025, that you can use with a grease gun, # L30100, to limit the mess. Also, you have to make sure that the grease used is compatible with the grease still on the bearings and in the hub. If you are not sure then you will need to completely remove the old grease before...
