What Are OEM Truck Parts?
OEM stands for Original Equipment Manufacturer. These parts are made by the same company—or an approved vendor that built the part originally installed on your truck at the factory.
- Built to the exact original specifications
- Typically carry the manufacturer’s logo or branding
- Generally sold through authorized dealers or service centers
- Often come with a manufacturer-backed warranty
- Usually more expensive than aftermarket options
OEM parts are ideal when you want guaranteed compatibility, consistent quality, and peace of mind—especially for critical systems like brakes, drivetrains, and electronics.
What Are Aftermarket Truck Parts?
Aftermarket parts are made by companies not affiliated with the truck’s original manufacturer. These parts are designed to match the function and fit of the OEM version—but pricing, quality, and features can vary.
- Often less expensive than OEM parts
- May offer enhanced performance or durability in some cases
- Widely available from independent suppliers
- Quality varies by manufacturer and brand reputation
Many trusted aftermarket brands like Bendix, Meritor, and Timken—produce high-performance parts used by fleets worldwide.
