This 8 Bolt on 6.5 inch bolt pattern brake drum hub is generally used on heavy-duty land trailers like utility, RV or cargo trailers in a drum brake system. This painted brake drum hub is compatible with 6,000 - 7,000 lb capacity axles with 5/8" studs and a #42 spindle, using a 1 1/4” x 1 3/4” bearing combination. This particular listing for this brake drum comes with bearings, seals, and a cotter key needed to fit the drum hub onto a 7,000 lb axle.
The kit includes inner bearing #25580 with an inner diameter of 1 3/4", outer bearing #14125A with inner diameter of 1 1/4", one zinc-plated cotter key to secure the castle nut once it has been properly installed, and two #42 spindle seals with inner diameters of 2 1/4" and 2 1/8". You will only need to use one of the seals and it gets installed on the back of the drum hub, so measure your spindle and previous seal and use only the correct sized seal when you are installing the drum.
This 8 Bolt brake drum hub is painted black and is commonly seen on utility trailers with Electric Drum Brakes or on some Freshwater Boat Trailers with Hydraulic Drum Brakes. You would not usually see this type of braking system in saltwater. If you need to replace the other parts of your Trailer Brakes, like the Backing Plate, or Electric Cluster you can purchased those parts separately. This is the Drum Hub with a bearing kit, so if you need Lug Nuts, bearing buddies, or Dust Caps you can always add them to your cart.
