What DMA Industries makes

DMA Industries is a private-label supplier, manufacturer, and distributor of aftermarket replacement parts for the North American automotive and heavy-duty markets. The company builds programs under its retail and warehouse-distributor customers' brands, and it also sells its own brands: Bulldog HD for heavy-duty ride control, SenSen, TekMaster, Atlas Lift, and Atlas Industrial. DMA describes itself as the number one private-label supplier in the North American automotive aftermarket, a claim the company makes about its own position.

The product range centers on ride control and undercar parts. Core lines include shock absorbers and struts, complete strut assemblies (sold as Speedy Struts), air suspension systems, coil springs, brake rotors, brake wear sensors, and fuel pumps. In 2024 the company added electronic suspension and expanded its fuel-pump and brake lines, and in 2026 it broadened its complete strut assembly coverage. Products move through several channels at once: original equipment service parts for dealerships, big-box automotive retailers, traditional wholesale distributors, and e-commerce retail.

Unlike a captive process shop, DMA's model is built around branding, engineering, packaging, logistics, and distribution wrapped around a global manufacturing base. The company sources and manufactures through factories in seven countries and opened a dedicated shock-and-strut factory in Thailand in 2024. That structure lets DMA run private-label programs end to end for customers who want a single partner from product design through the warehouse shelf.

Distribution and footprint

DMA runs more than 2.5 million square feet of distribution space across the United States, concentrated in the Carolinas. Its distribution centers sit across Horry, Marion, and Columbus counties in North and South Carolina, with the corporate home in Tabor City, North Carolina and a corporate office in Loris, South Carolina.

The largest recent addition is a 1.4 million-square-foot facility in Greer, South Carolina, opened in 2026 less than four miles from the Inland Port of Greer. The Greer site operates as a Foreign Trade Zone and is C-TPAT compliant, and DMA equipped it with ultra-wideband inventory tracking, camera-based put-away verification, and an upgraded proprietary warehouse management system. The Inland Port connection gives DMA rail access to the Port of Charleston, shortening the path from ocean freight to the distribution network. This kind of logistics depth is what lets a private-label supplier promise speed-to-market on high-turn parts like struts and brake components. Buyers evaluating nearshoring and inventory positioning tend to weigh exactly these factors.

Ownership and history

DMA Industries opened its doors in 2008 in Tabor City, North Carolina, founded by John Treece, who serves as Chairman and Chief Executive Officer, and Steve Bertling, its former Chief Financial Officer. The company grew from two employees to more than 100 and from a single warehouse to a network of distribution centers across the Carolinas. It remains a privately held, founder-led company with no parent.

The leadership team pairs the founder with executives drawn from the wider automotive aftermarket. Fred Snow became President and Chief Operating Officer in January 2025, having joined as COO in 2023 after more than two decades at HELLA, most recently as President of HELLA's US automotive sales business. Kevin Stock, a CPA, joined as Chief Financial Officer in April 2024 after serving as CFO of CRP Industries. Maria Treece is Chief Process Integration Officer, Olga McIntyre is Chief Information Officer, and Jordan Treece leads product management and marketing. The company was named to Business North Carolina's NCFast40 list of the largest-growing mid-cap companies for six consecutive years as of late 2023.

Trade compliance and quality

DMA operates its Greer distribution facility as a Foreign Trade Zone and holds C-TPAT compliance, the US Customs program for vetted, secure supply chains. These are trade-compliance credentials rather than a quality-management certificate. The company has not published an ISO 9001 or IATF 16949 quality-system certificate, and none is claimed here on its behalf. For a private-label supplier, quality assurance is described at the program and product level, backed by in-house engineering and product development rather than a public plant certificate.

Known customers

Most of DMA's customer relationships run under private-label programs and are not disclosed. One is on the public record through industry awards:

Beyond that documented relationship, DMA states it serves original-equipment service channels for car dealerships, big-box automotive retailers, traditional wholesale distributors, and e-commerce retail. It does not name those accounts publicly, which is normal for a private-label supplier whose programs carry its customers' brands rather than its own.

Sourcing evidence

DMA's manufacturing and sourcing sit outside the standard US import record under its own name. Its goods reach the United States through third-party logistics providers and distribution partners rather than direct company-name bills of lading, so public US customs data shows only a handful of shipments tied to the DMA name. The real footprint is a manufacturing network across seven countries, anchored by the 2024 Thailand shock-and-strut factory, feeding the Carolinas distribution centers.

What the record does show is consistent with the company's account: a private-label supplier that manufactures abroad and moves inventory through owned and leased distribution space at scale, now routed increasingly through the Greer Foreign Trade Zone and the Inland Port. Absence of a large direct-import record is not evidence of low volume; it reflects a 3PL-and-distributor import structure. Buyers who want lane-level detail should request it directly.
