This Dexter hub-and-drum assembly is designed for serious towing, built for 8,000-lb E-Z Lube trailer axles with #42 spindles. The cast iron construction gives it the strength to handle heavy loads while maintaining smooth, consistent braking under pressure. With a 12-1/4" diameter and 4-1/2" width, it provides the surface area needed for dependable braking performance on every trip.
Everything you need for a proper install is right in the box—inner bearing (25580), outer bearing (02475), both matching races (25520 and 02420), a 10-36 grease seal, grease cap, wheel bolts, and lug nuts. That means no hunting down extra parts or guessing at compatibility. The 8 on 6-1/2" bolt pattern with 9/16" studs makes wheel mounting straightforward and secure.
Keeping bearings greased is one of the most important parts of trailer maintenance, and this assembly makes it quick and clean. The E-Z Lube-compatible grease cap has a rubber plug that lets you access the zerk fitting on the spindle without taking the hub apart. Just attach a grease gun, add fresh grease, and it flows directly to the inner and outer bearings for long-lasting protection against wear and corrosion.
Whether your setup uses electric or hydraulic drum brakes, this hub-and-drum assembly is ready to go. It’s built to work with standard 12-1/4" brake assemblies, giving you the flexibility to match your existing system or upgrade down the road. The sturdy iron drum surface ensures even contact with brake shoes for confident, consistent stops.
With a 4,000-lb weight rating per hub and a 4-3/4" pilot hole diameter, this assembly is built for balance and durability. From towing heavy equipment to long-distance hauls, its precision-machined parts and factory-fit bearings help ensure smooth rotation and long service life under demanding use.
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"

Ratings & Reviews
Was told this came with bearings pre greased. Came with neither
Does not look like right for ez lube spindle.
The 1996 tandem axle trailer had two different Dexter axles; one manual and one EZ Lube. The standard axle had manual adjust brakes, the EZ Lube had self adjusting brakes. After disassembling the two types of drums and taking measurements of drums & spindles, Josh with etrailer was able to ensure I ordered the correct parts. I replaced the EZ Lube drums and the self adjust brakes with the new Dexter drums and Terran self adjust brakes. The manual drums and brakes were replaced with new TruRyde drums and the Terran self adjusting brakes. Everything is working well.
Dexter trailer hubs and brakes where exact fit for our Rockwood travel trailer. Installation was straight forward and brakes have worked perfectly since installed. Delivery of parts was prompt. Since then I have ordered and installed a powered tongue jack which also fits our camper and works well.
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.

Parts for my old dexter axlesAfter auto parts, trailer dealers and mechanics shops failed me, I found the part on Etrailer. It came quickly, with all the hardware and was $100 less than the trailer dealer told me it would cost if he could even find one. Great job, etrailer.
