Saltwater and wet conditions are rough on steel parts. The galvanized Dexter hub-and-drum assembly is built for marine use and tested to withstand 500 hours of continuous salt-spray exposure. That zinc coating fights off rust and corrosion so your hub keeps turning smoothly season after season, even when the trailer sees regular dunking at the ramp.
This assembly fits 3,500-lb axles with #84 spindles and works with 10" × 2-1/4" electric or hydraulic brake assemblies. It includes inner bearing L68149, outer bearing L44649, both races, grease seal 58846 (1.719" ID / 2.565" OD), grease cap (1.98" flange diameter), and zinc-coated lug nuts. With the races already installed, it’s ready to pack with grease and mount right out of the box, simplifying the rebuild or replacement job.
The 10"-diameter by 2-1/4"-wide drum gives consistent braking surface for dependable stopping power. It’s rated for 1,750 lbs per wheel end and uses a 5 on 4-1/2" bolt pattern with 1/2" × 2-1/4" wheel bolts, covering common wheel sizes from 13" to 15". The precisely machined races and bearings keep things running true for smooth rotation and even shoe contact.
Whether you’re refurbishing an old trailer or keeping a spare hub for roadside repairs, this marine-grade Dexter assembly makes things straightforward. The bearings, seal, and hardware are included, so there’s no hunting for extra parts. It goes on easily, fits tight, and holds up to long-distance towing and heavy use without fuss.
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"

I am very sorry to hear that you were told everything was USA made Marc, as you saw the Dexter hub is made here in the US, but the bearings we pack are made in China. We do have USA made bearings but they would need to be purchased separately. For this hub you will want to get the Timken Bearing Kit for Lippert, Dexter, and AL-KO Axles - 3,500 lb with #84 Spindle # TMK52VR, you will want to order one set per hub. Once again, my apologies.
Do you have a question about this Trailer Hubs and Drum?
