If you're building or repairing trailers, these pre-assembled hub kits are going to save you so much time and hassle! Each kit comes with everything you need for one wheel assembly - the 4 on 4 inch bolt pattern hub is already pressed onto the BT8 spindle, the L44643/L44610 bearings are installed and properly greased, and all the necessary hardware is included. The BT8 spindles are 8.75 inches long and work with most standard 2,000 pound capacity trailer axles, which covers a huge range of utility trailers, boat trailers, and small cargo trailers. The wheel studs are 1/2 inch diameter by 1-5/16 inches long, which is standard for most trailer wheels. Each complete set includes the hub and spindle assembly, two bearings, a 12192TB seal, rubber dust cover, four 1/2-20 nuts, cotter pin, and the spindle nut with gasket. The alloy steel construction means these can handle serious loads without bending or failing, and the pre-greasing means they're ready to install right out of the box. I've used similar kits for trailer repairs and the time savings is incredible - no more pressing bearings, packing grease, or trying to source all the individual components separately. The quality is solid with good machining on the spindles and hubs, and everything fits together properly. Whether you're building new trailers from scratch or replacing worn-out hubs on existing trailers, having eight complete sets means you can do multiple trailers or keep spares on hand. Just make sure to check the compatibility with your specific axle type before ordering, but for most standard 2,000 lb axles, these are perfect replacements that'll get your trailers rolling smoothly and safely.
