OEM Parts & Manufacturer Certifications

Why use OEM parts?

1. Quality

We’re referring to fit and function here. Yes, you can find an M10 x 1.25 bolt at Home Depot, but is it made from the same material as the original? Does the thread pitch really match? This is a simplistic example, but it applies even more so in the case of complicated parts and assemblies. Have you ever gone to install a new replacement part and the holes didn’t match up? This is much less likely to happen with OEM parts designed by the manufacturer.

2. Warranty & Support

Occasionally the installation of a non-OEM part poses a threat to warranty coverage on a particular piece of equipment. If your hydraulic system fails because someone changed with fluid that doesn’t match manufacturer specifications, you may be on the hook to rebuild it yourself rather than filing a warranty claim. OEM parts themselves may also have a better guarantee than those from 3rd-party suppliers or will fitters.

3. System Compatibility

With the increasing use of connected sensors and integrated data collection to monitor and record operating conditions, making sure related components are compatible is a primary concern. Manufacturers commonly use proprietary software to control machine-to-machine (M2M) communications, and other aftermarket suppliers may not have access to the code that makes everything work together.

4. Reliable Distribution

Large manufacturing companies have been around for years, meaning they’ve had a long time to refine their supply chains and distribution networks. While you may believe you’re saving a few hundred dollars by buying that expensive part from a “disruptive” vendor, the only thing likely to be disrupted is your work schedule when the part doesn’t show up on time.

5. Durability

A part is a part, right? Except you have no idea what’s in the alloy or plastic that the part is made from. Auto makers have spent over 100 years formulating recipes for sheet metal and coatings that resist corrosion and contribute to increased safety standards. Is that fender produced in Malaysia made of the same stuff? Nobody knows.
