Long trips and steep grades can push trailer brakes hard. This Dexter 10" hub-and-rotor assembly is built to keep temperatures in check with its vented design that channels air through the rotor to prevent overheating and fade. Machined surfaces reduce runout and help the rotor stay true for smooth, consistent braking mile after mile.
Moisture, spray, and salt can eat through unprotected metal fast. The zinc finish on this assembly forms a tough barrier against corrosion and wear, making it ideal for trailers that see regular water exposure. The cast iron construction adds strength and rigidity so the hub holds up under heavy use.
This hub is designed for straightforward compatibility with standard bearings—inner bearing L68149 and outer bearing L44649—with matching races (L68111 and L44610) already pressed in. The grease seal RG06-050 (1.719" ID, 2.565" OD) fits when running traditional grease, or the assembly can be paired with the Kodiak XL ProLube Kit #XLPROLUBE1980KIT for an oil-bath setup.
Rated for 3,500 lb axles (up to 3,700 lb capacity) and compatible with 14" or larger wheels, this 5-on-4-1/2 pattern hub uses 1/2" wheel bolts and a rotor diameter of 9-3/4". Precision machining keeps it balanced and true, giving you steady braking performance without vibration or chatter.
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"
