What WAI Global makes

WAI Global is an automotive aftermarket manufacturer and supplier built around rotating electrical, the alternators, starters, generators, and voltage regulators that keep a vehicle's charging and starting systems running. Its headline positioning is coverage of 100% NEW rotating electrical, meaning newly built units rather than remanufactured cores, with an emphasis on late-model applications so distributors can stock current vehicles as they age into the repair market.

Beyond rotating electrical, WAI runs three more product families. Small motor covers wiper motors and linkages, window regulators and motors, transfer case motors, and washer pumps. Engine management covers sensors, ignition coils and distributors, electronic throttle bodies, and solenoids. A vehicle electronics line and, more recently, a range of electric-vehicle charging cables and accessories round out the catalog. WAI sells under its own brand and as a private-label supplier to distributors and tier suppliers in the aftermarket channel, and it expands coverage on a regular cadence: the company reported adding 109 new part numbers in a single quarterly New Part Introduction cycle in mid-2026.

The product lines are engineered for a wide set of applications, not just passenger cars. WAI publishes dedicated coverage for heavy-duty Class 6 to 8 trucks and buses, agricultural and industrial equipment, marine, powersport, and outdoor power equipment. That breadth is the strategic point of a rotating-electrical specialist: one part category, many vehicle platforms, sold through the same distribution channel.

Ownership and history

WAI Global is the operating name of Wetherill Associates, Inc., founded in 1978 and now headquartered in Miramar, Florida. The company describes itself as charging forward since 1978, with more than 45 years in the aftermarket. It is privately held; no listed parent or disclosed financial sponsor is published, and this profile does not assert one.

The company has grown by acquisition as well as organic coverage. In January 2025 WAI acquired ACI Automotive from Standard Motor Products, adding washer pumps, window regulators, and door components, with a manufacturing operation in Lewisville, Texas. WAI's leadership framed the deal around managing complex, technical, and SKU-intensive product lines, the operational discipline that a broad aftermarket catalog demands. Day-to-day leadership on the public record includes Ryan Moul, Chief Executive Officer, and Seth Moul, CEO for North America, with Rick Evans as Director of Distribution.

Distribution and operations

For an aftermarket parts company, distribution capability is the product as much as the parts are. WAI's primary US hub is its Memphis Distribution Center, located in the Memphis metro at Southaven, Mississippi. In July 2026 the company announced a 75,000-square-foot expansion of that center, paired with a new cloud-based warehouse management system and equipment upgrades aimed at faster picking, better inventory visibility, and a foundation for future automation.

WAI's model rests on global sourcing feeding a responsive North American distribution network, which is visible in its import record: more than 6,500 US import shipments are on file, with activity continuing into 2026. The named foreign suppliers on those bills of lading are China-based rotating-electrical component makers, consistent with a company that sources components and units internationally and stocks them deep in the US for same-market availability. Buyers weighing tariff exposure on imported electrical components will find that sourcing footprint relevant when comparing aftermarket suppliers.

Certifications and quality

WAI positions its products as OE-quality and describes engineering, testing, and validation as part of how it builds parts, with an argument that 100% NEW units reduce comebacks versus remanufactured alternatives. The company did not publish a specific ISO 9001 or IATF 16949 certificate or scope on the pages reviewed for this profile, so no formal quality certification is claimed here. A buyer running supplier qualification should request current certificates directly.

Sourcing evidence

WAI Global's US import record is large and active: 6,573 sea-import shipments on file, with the most recent recorded January 20, 2026, consigned to its Memphis-area distribution operation in Southaven, Mississippi. The named suppliers include Zhejiang Magneto Electromotor and Ningbo Pro Tech Auto Electric, both China-based makers of automotive electrical components, matching WAI's rotating-electrical and engine-management focus. That pattern, electrical components and units imported into a large domestic distribution center, is the signature of an aftermarket supplier stocking for immediate North American availability rather than building to order.

Coverage caveats apply. These are US ocean-freight records only; air, truck, and rail movements do not appear, and some manifests name freight intermediaries rather than the ultimate manufacturer. Product categories come from declared manifest codes, which are noisy. Absence of a record is not evidence of absence.
