Aftermarket Performance Group

Aftermarket Performance Group

Aftermarket Performance Group (APG) is a family office based in Rexburg, Idaho, that owns and operates a vertically-integrated network of aftermarket performance parts companies. The family office structure is not publicly documented, and no founding year, named principals, or wealth origin details have been disclosed. APG's website presents the entity as a centralized operating team that coordinates multiple parts businesses under one umbrella. APG focuses entirely on the automotive aftermarket performance parts sector, with its integrated companies covering administrative services, retail placement, wholesale distribution, and online sales. The group does not publicize specific portfolio companies, deal sizes, or co-investors. Its geographic footprint appears limited to the United States, based on the Rexburg headquarters and the domestic focus of the aftermarket industry. The firm does not disclose AUM, deployment figures, team size, or additional offices. No adjacent philanthropic vehicles or operating business names beyond the APG brand are listed. No recent operational events are publicly available. The structural differentiator of APG is its vertically-integrated family office model applied to a niche industrial sector—aftermarket performance parts. By owning and coordinating multiple companies that each handle a different part of the supply chain, APG functions less as a traditional investment office and more as an operating company with a family office governance structure.
