Saltwater and moisture can eat through a hub in no time, but this marine-grade assembly is built to stand up to it. The galvanized finish offers excellent corrosion resistance and helps prevent rust even after repeated water exposure. It’s the kind of durability you want when your trailer sees wet ramps or long hauls in damp conditions.
This hub is made for consistent towing strength. It fits 4,200-lb axles and carries a 2,100-lb capacity per hub. The sturdy iron construction gives it the backbone to handle heavy use day after day without flex or fatigue.
Both the inner and outer bearings use the same L68149 spec with a 1.378" inner diameter, so you get a uniform fit that keeps rolling resistance low. The pre-installed L68111 races are set from the factory so you don’t have to hammer them in. Just add your bearings, grease seal (010-172-00), grease cap, and lug nuts (all sold separately), and it’s ready to mount.
The bolt circle makes wheel matching straightforward. With a 5 on 4-1/2" pattern and 1/2" diameter x 1-5/16" long studs, it fits wheel sizes from 13" up to 17-1/2". That flexibility makes it easy to pair with common trailer wheel setups without extra measuring or guesswork.
Each hub meets QAI and CSA certification standards for quality and safety. That means it’s been tested for performance before it ever hits your axle, giving you confidence every time you tow.
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"
