When you need a hub that can stand up to everyday hauling, this Dexter idler hub assembly is made for it. It fits 5,200-lb axles and is built from sturdy iron for lasting durability under load. Each hub supports up to 3,000 lbs and uses the proven 25580 inner bearing (1.75" ID) and LM67048 outer bearing (1.25" ID) setup trusted on heavy-duty trailers. The 6-on-5-1/2" bolt pattern matches easily with a wide range of 14" to 16-1/2" wheels for dependable performance mile after mile.
This kit comes ready with everything you need to get rolling again — bearings, races, grease seal, grease cap, wheel bolts, and lug nuts are all included. No extra digging for matching hardware or guessing which components fit. Just pack your bearings, slide the hub in place, tighten the 1/2"-diameter studs, and you’re set to tow.
Dexter keeps things straightforward with parts that match industry standards. The hub uses the same bearing set (25580 inner and LM67048 outer) found on most 5.2K and 6K spindles like the TruRyde TRU57FR or TRU37FR. The grease seal (10-10) fits a 2.125" inner and 3.376" outer diameter bore, giving a precise fit that keeps grease where it belongs and helps prevent contamination or leaks over time.
From boat trailers to RV rebuilds, this hub is trusted because it’s simple, solid, and proven reliable. The iron construction resists wear from heat and load cycles, while Dexter’s tight machining tolerances mean the bearings seat right every time. Whether you’re refreshing an older setup or keeping a spare on hand for roadside peace of mind, this hub is made to keep your trailer rolling smooth and true for years to come.
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"

Hello, everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at this Dexter Trailer Idler Hub for 5,200 pound axles, has the 6 on 5 1/2 inch bolt pattern. Now, this trailer hub assembly is designed to fit onto idler axles, which are axles without brakes. The parts all on this table are all included. Includes the idler hub itself, the inner bearing race, the outer bearing race, which is already pre-installed into the hub. Comes with the outer bearing right there.
Comes with the inner bearing. Comes with the grease seal that'll go over this when your inner bearing is installed, and the grease cap, which would cover your outer bearing. And also, six of the 1/2 inch by 20 size lug nuts. Now, the part numbers for all these parts are listed on the product page of this item. Now, this is a sturdy iron construction.
Few specs again, application, fits a 5,200 pound trailer axle, and it will be used for wheel size anywhere from 14 1/2 inches up to 16 1/2 inches. Bolt pattern on this is 6 on 5 1/2 inch. Wheel stud size, 1/2 inch diameter. So again, they require the use of 1/2 inch by 20 size lug nuts, which are included. And the weight capacity on this idler hub is 3,000 pounds.
But that should do it for the review on this Dexter Trailer Idler Hub for 5,200 pound axles with the 6 on 5 1/2 inch bolt pattern.

Excellent. They work great. Keep up the Maintence and they will probably never fail. I am also a big fan of bearing buddies.

These idler hubs are great! Very happy with them. I have used the trailer several times and there haven’t been any issues. Finally no more squeaking and squealing from bad bearings and hubs.
