This aftermarket M-Parts hub replaces Dexter 008-430-03 and is used on 9K, 10K General Duty, and 13G axle assemblies manufactured after July 2009. It is part of the updated post-2009 two-piece hub/drum system, pairing with the 9-123-03 brake drum (sold separately).
Dexter discontinued their earlier one-piece 8-415 hub/drum design in 2013. The 008-430-03 hub is the required replacement for that legacy assembly, maintaining the updated bearing spacing introduced in 2009.

Dexter introduced new bearing spacing on 9K and 10K GD axles beginning in 2009. Earlier hub/drum designs (8-288, 8-232, 8-256 series) are not compatible with this post-2009 hub.
Always verify your axle tag, drum casting number, and measurements before ordering.
