What Industrial Parts Depot makes

Industrial Parts Depot, which trades as IPD, designs, manufactures, and distributes aftermarket replacement components for heavy-duty diesel and spark-ignited engines. The catalog covers pistons, cylinder liners, rebuild and overhaul kits, gaskets, valvetrain parts, bearings, seals, and head bolt and stud kits. IPD manufactures its pistons and gaskets in-house at its Carson, California facility and sources thousands of additional parts to meet engine-specific requirements. Its parts fit major engine platforms including Caterpillar, Cummins, Detroit Diesel, Waukesha, Mercedes, and Perkins, positioning IPD as an alternative to buying components directly from the original equipment manufacturer.

Several of IPD's products are its own engineered designs rather than plain replacements. The company produces IPDSteel articulated and two-piece steel-crown pistons for diesel engines, a Raised Edge Liner, induction-hardened and cuffed cylinder liners, cryo-treated head bolt kits, and its 1-2-3 Gasket Sets. IPD serves rebuilders and distributors across on-highway trucking, construction, marine, power generation, natural and methane gas, drilling, mining, and railway applications. As an aftermarket manufacturer, it competes on availability and engineering: its own materials note that some IPD parts, such as the raised-edge liner, address configurations that are not offered through the OEM channel.

Ownership and history

IPD was founded in 1955 by Bob Rasmussen and Walter Storm and has operated for 71 years, marking its 70th anniversary in 2025. The company built out its product range through the 1960s and 1970s, purchased Jahn's Piston Company in 1981, and developed the first three-ring piston for Caterpillar 3208 engines in 1984. It opened a Denmark office in 1995 and an Australia office in 1996, achieved ISO 9001:2000 certification through Lloyd's Register in 2007, and has been awarded a series of US patents for piston and cylinder-liner technology from 2008 through 2022. In 2023 IPD moved into a new headquarters in Carson, California, and expanded operations into Dubai around 2024.

IPD is a subsidiary of Storm Industries, a private industrial group connected to co-founder Walter Storm. Michael J. Badar has served as President since February 2018 and reports to the CEO of the parent company; per the company's own materials, he leads day-to-day operations across IPD's global footprint. The company describes a network of six locations on four continents, with headquarters and manufacturing in Carson, distribution branches in Cleveland, Ohio and Houston, Texas, and business offices and distribution centers serving Europe from Denmark, the Middle East from Dubai's Jebel Ali, and Australia and Southeast Asia from New South Wales. IPD reports more than 100,000 square feet of US warehouse space.

Certifications and quality

IPD states that it is an ISO 9001:2015 certified company and posts its certificate on its own site. Its quality-system lineage runs back to ISO 9001:2000, achieved in 2007 through Lloyd's Register, with the transition to the 2015 standard completed in 2018. The company frames quality around its in-house engineering and manufacturing of pistons and gaskets, and its patent record supports that positioning: it holds US patents for a cylinder liner with a cooling groove, an investment-cast two-piece steel-crown piston, a friction-welded two-piece piston with a fourth-groove design, and welded piston technology. These are self-published claims and self-posted certificate details rather than independently audited figures.

Known customers

IPD sells through a global network of distributors and engine rebuilders rather than through documented OEM programs, so named customer relationships are not part of the public record in the way they are for a direct production supplier.

The honest reading is that IPD is a brand sold into the independent heavy-duty aftermarket. Its customers are the shops and distributors that stock and install its parts, not a short list of named engine builders.

Sourcing evidence

IPD's US import record is consistent with an aftermarket engine-parts manufacturer that machines and finishes at home while sourcing components and tooling abroad: 1,038 sea shipments since January 2015, with the most recent on September 19, 2026, averaging roughly 8.2 twenty-foot-equivalent containers per month. The engine-parts supply base is concentrated in Taiwan, which accounts for about 400 shipments, alongside suppliers in Brazil, Italy, and India. Bills of lading name the most active engine-component partners, and buyers weighing tariff exposure will note the geographic spread:

By declared HTS code, the mix reads as engine internals: bearings under 8483.30, pistons, liners, piston pins, and cylinder-head gaskets under the 8409 headings for compression-ignition and spark-ignition engine parts, oil seals under 4016.93, and lock washers under 7318.21. That is the profile of a company importing engine hardware to finish, kit, and distribute, not finished vehicles.

Two coverage notes matter for reading this data. IPD's single largest customs relationship by count is Combilift ULC, a forklift manufacturer shipping from Belgium and Ireland; those are materials-handling machines for IPD's own warehouses, not engine-parts sourcing, which is why Europe shows as roughly 48 percent of shipments while the engine supply base is really Asian and South American. And these are US ocean-freight records only: air, truck, and rail movements do not appear, some records name freight intermediaries rather than manufacturers, and manifest product codes are noisy. Absence of a record is not evidence of absence.
