NAICS 336390 – Other Motor Vehicle Parts Manufacturing encompasses the production of specialized motor vehicle components that do not fall under standard categories like engines, transmissions, or body panels. This includes aftermarket and custom-fabricated parts such as suspension components, drivetrain accessories, towing hardware, specialized fasteners, and engineered chassis elements used in military vehicles, tactical transport platforms, and heavy-duty off-road applications. These parts are often designed to meet stringent military specifications for durability, corrosion resistance, and operational reliability under extreme environmental conditions. The sector plays a critical role in sustaining and modernizing the Department of Defense’s ground vehicle fleet, supporting maintenance, repair, and overhaul (MRO) operations across armored vehicles, logistics trucks, and expeditionary mobility platforms. Top contractors in this space include EVERSTONE INDUSTRIES LLC and ALLOY SLING CHAINS, LLC, both of which are small businesses specializing in precision-engineered, high-strength components for defense-grade applications. These firms typically operate as niche suppliers, leveraging advanced metallurgical processes and custom fabrication techniques to meet unique military requirements. The competitive landscape is characterized by a concentration of specialized small businesses rather than large primes, with a strong emphasis on technical certification, quality control, and Just-In-Time delivery capabilities. The Department of Defense is the dominant buyer, driving demand through sustainment programs for legacy and modernized vehicle platforms, including the Family of Medium Tactical Vehicles (FMTV), HMMWV upgrades, and tactical wheeled vehicle modernization initiatives. Procurement is often tied to depot-level maintenance contracts and urgent operational needs. The market remains opportunity-dense for qualified small businesses with expertise in metal forming, welding, and compliance with MIL-SPEC standards. Demand is steady and recurring, fueled by lifecycle support requirements and the need for domestic supply chain resilience in critical vehicle subsystems.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 336390 work as a small business.

1,000 employees
Applies to the whole industry code

The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.

13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
