Rust is one of the biggest headaches when it comes to trailer hubs, especially around saltwater. This Dexter hub assembly is marine-grade and galvanized for long-term corrosion resistance. The zinc plating has a 500-hour salt spray rating, meaning it can handle constant exposure to the elements without breaking down. Whether you’re dunking a trailer at a boat ramp or pulling through slushy roads, this coating keeps the hub in solid shape.
No need to track down separate components. This kit includes both inner and outer bearings (L44649), matching races (L44610), grease seal (10-9 with 1.5" inner diameter and 1.987" outer diameter), grease cap, and galvanized lug nuts. It’s designed for 2,200-lb axles with BTR spindles and fits wheels from 13" to 15". With a 5 on 4-1/2" bolt pattern and 1/2" wheel studs that are 2" long, it’s ready to install right out of the box.
Getting the right fit matters most when you’re stuck roadside or rebuilding an older trailer. This hub works with standard BTR spindles using L44649 bearings on both inner and outer sides—each with a 1.063" diameter. That makes sizing and replacement simple, even for older or mixed setups. Just confirm your spindle measurements and slide the hub into place for a snug, reliable fit.
Each hub carries a weight capacity of 1,100 lbs and a flange diameter of 6-1/2". That means solid performance mile after mile under steady use. The durable construction holds up to repeated launches, heavy towing, and rough conditions without giving up its smooth rotation or tight seal.
When bearing failure happens on the road, having a spare can make all the difference. This pre-assembled Dexter hub packs easily in your tow vehicle so you can swap it out fast when needed. Since it’s already equipped with bearings, seal, cap, and lug nuts, it’s a ready-to-go spare that prevents downtime and gets you rolling again quickly.
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"

18 month update. Hubs work as they should. No signs of rust after 18 months of saltwater boat launches.
