Good but Bearings Not Included

Just a heads-up: bearings and seal sold separately. That’s not clear on the main page. Once I got the right parts, everything worked perfectly.

Strong Build for Heavy Loads

I haul machinery and needed beefier hubs. These deliver—zero flex, no heat issues. Studs haven’t loosened even after off-road use.

Needed Minor Truing After Mounting

Wheel wasn’t perfectly true out of the box. A few adjustments and it settled in. Braking is even and smooth now. Still a solid 4-star product.

Easy Installation, No Hassles

Put this on a weekend rebuild. Pre-installed races made a big difference. No need to press anything. Just pack bearings and go.

Great Upgrade from 7/16" Studs

Upgraded from smaller studs for safety. The 9/16" size makes a noticeable difference in wheel security. Highly recommend for heavy-duty use.
