Dexter Axle Hub and Drum Kit K08-247-90 for 3.5K Axle, 5 on 4.50 Bolt Circle, 1.718 Inch Seal

The Dexter Axle Hub and Drum Kit K08-247-90 is a complete hub-drum assembly built for a 3.5K trailer axle. It is engineered for the 5 on 4.50 inch bolt circle with 1/2 inch-20 studded hubs, uses a 1.718 inch seal, and comes with a standard grease cap. This kit is designed as a full replacement unit, giving trailer owners and repair shops a single, correctly matched hub and drum assembly rather than sourcing hub and drum components separately and risking a mismatch in bolt pattern, stud size, or seal diameter.

Because trailer axle hub-drum assemblies must match the axle's stud pattern and seal bore precisely, the K08-247-90 kit is specified to the 5-4.50 bolt circle and 1.718 inch seal combination used on 3.5K rated axles. Installing a correctly matched kit helps maintain proper wheel bearing seating, brake drum concentricity, and seal integrity, which are all critical to safe towing. The kit includes a rubber plug as part of its assembly.
