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.
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.
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.
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.
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.
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
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.
Fast delivery.
