Hey Michael,

Thanks for the part number of your Dexter Axle. Per your build sheet you'll need bearing kit # BK3-100. This includes the inner bearings # 25580, outer bearings # 15123, and grease seals # 10-36.

Hi there. Some literature was saying the 5100lb axle has a 2.125 spindle. Then others are saying it has the 2.250 spindle. Nothing is denoted on the sticker of the axle. What's the best way for me to find out which grease seal I need for sure? or are you confident that it would in fact be the 2.250 seal?

@BryanD it can vary between axles with this capacity so if you want to be sure you can have Dexter (or whoever the manufacturer is) identify the axle using the serial number on the tag, or you can measure.
