Great for Oil Bath Maintenance

Runs cooler than my old grease-packed hubs. The oil cap lets me check levels without disassembly—huge time saver on long hauls.

Smooth Installation with Pre-Installed Races

Saved me the hassle of pressing in races. Everything aligned perfectly with my axle—spun freely with no drag.

Good Fit but Bearings Sold Separately

Note to buyers: you’ll need to buy bearings and seal separately. Once installed, braking and spin are flawless.

Exactly What My 17.5" Wheels Needed

Fits my larger wheels with no clearance issues. 5/8" studs provide a secure lug grip—no loosening even on rough terrain.

Perfect Replacement for Dexter [****]

Replaced both hubs on my 8K tandem axle trailer. Bolt pattern and brake fit were spot-on. The oil cap design makes checking lube a breeze.
