What Rotomaster makes

Rotomaster is a turbocharger and turbo-component specialist. Its catalog spans complete turbocharger assemblies, replacement cartridges (the center housing rotating assembly, or CHRA), service and rebuild kits, billet compressor wheels, electronic actuators and variable-geometry control solenoids, oil and coolant lines and line kits, exhaust adapters, and pedestals. The parts cover diesel and gas-powered applications across heavy-duty, medium-duty, light-duty, passenger car, power sports, industrial, and marine vehicles.

The company sells into two channels at once. It supplies original equipment manufacturers as a Tier One OES source, and it sells brand-new and remanufactured turbochargers, cartridges, and service kits directly into the automotive aftermarket. That aftermarket line lets independent shops and technicians rebuild turbos with matched components rather than replacing the whole unit. At its 2023 acquisition, the company said its range covered more than 75% of addressable vehicles-in-operation.

Ownership and history

Rotomaster traces to 1978, when it began in Vancouver, Canada as ADP Distributors, an authorized distributor and remanufacturer of Garrett turbochargers serving the heavy-duty aftermarket. As OEM aftermarket support thinned in the late 1990s, the founders used two decades of remanufacturing and reverse-engineering experience to start designing and building brand-new turbochargers, initially for discontinued part numbers the OEMs had dropped. The business relaunched in 2002 as the Rotomaster turbocharger, component, and service-kit brand, then expanded through Canada, the United States, and Europe and set up two joint ventures in China, securing ISO 9001 certification at each facility.

In October 2023, Cloyes Gear & Products acquired Rotomaster; deal terms were not disclosed, and BMO Capital Markets advised Rotomaster. Cloyes is a producer of automotive timing systems and components and had itself been acquired by the private equity firm MidOcean Partners in February 2022. The combined organization is now branded MOP-Cloyes and covers both the Cloyes and Rotomaster brands. Group leadership sits at that parent level: John Hanighen is chairman, president, and chief executive, and in August 2026 the group named Robert Frazier chief operating officer and Doug Havekost chief financial officer. Rotomaster is headquartered in Surrey, British Columbia, with a United States office in Mesa, Arizona and fulfillment centers in Arizona and Arkansas.

Certifications and quality

Rotomaster states that its manufacturing locations in Canada, the United States, and China are ISO 9001 certified, and it cites the current ISO 9001:2015 standard. The company does not publish a certificate date or certifying body on its site, so the claim is reported here as the company states it. Its quality record on the history page runs back through earlier ISO 9001 cycles from the years when it first industrialized new-turbocharger production. Rotomaster backs its products with a one-year warranty and runs technical support, installation guides, and a rebuild-and-return program for aftermarket customers.

Sourcing evidence

Rotomaster's United States import record shows 61 sea shipments on file, with the most recent logged July 21, 2026, so the company is an active importer. The named foreign shippers are concentrated in China and include Changzhou E&E Turbo Power and Wuxi Xingteng Power Technology, along with Rotomaster Wuxi Turbocharger, which is the company's own China joint-venture operation, and a Shanghai logistics intermediary. That pattern fits a turbo maker that builds and assembles components through overseas partners and its own JV, then distributes finished turbochargers, cartridges, and kits into North America. Buyers weighing nearshoring or tariff exposure should note the China-weighted inbound footprint.

These are United States ocean-freight records only. Air, truck, and rail movements, cross-border Canada flows, and any shipments into non-US destinations do not appear; some records name freight intermediaries rather than manufacturers; and product categories come from declared manifest codes, which are noisy. Absence of a record is not evidence of absence.
