What wipers does GM use?
General Motors uses a mix of windshield wiper blade suppliers, with GM’s own ACDelco brand being common on many vehicles. The exact supplier varies by model, year and regional market.
Overview: How GM sources wiper blades
GM does not rely on a single supplier for all its wiper blades. The company sources OE blades from GM’s own ACDelco line as well as from other major manufacturers depending on the vehicle, production year, and geographic region. In practice, some GM models ship with blades branded by ACDelco, while other models or regional markets may use blades from Bosch, Valeo, or Trico under OEM arrangements or as approved replacements.
Regional and model variations
Regional manufacturing and supply agreements mean that the exact blade brand and attachment style can differ from one GM model to another, and from North America to Europe or Asia. As a result, the blade you need for a given GM vehicle may be ACDelco-branded or come from a third-party supplier selected for that market.
Commonly cited categories in GM’s wiper supply ecosystem include:
- ACDelco Original Equipment (GM OE) wiper blades
- Bosch OEM wiper blades (used on some GM models in certain regions)
- Valeo OEM wiper blades (used on some GM models in certain regions)
- Trico OEM wiper blades (used on select GM models or as aftermarket replacements)
In short, GM’s wiper supply is diversified, and the exact blade brand for your vehicle depends on factors like model year and regional supply arrangements. When in doubt, consult the vehicle’s owner’s manual or check GM’s official parts catalog for the precise OE blade specification.
Identifying the correct wiper blades for your GM vehicle
To ensure you purchase the right blades for your GM car, follow these steps so you know the correct size, attachment type, and brand alignment with OE specifications.
- Check the owner’s manual for the recommended blade size and type (driver and passenger sides may differ).
- Use GM’s official parts lookup or the ACDelco parts catalog by entering your vehicle’s year, make, model, and trim to confirm the exact OE blade part number.
- Inspect your current blades to identify length(s) and the attachment style (hook, pin, or bayonet) to match the replacement.
- Decide whether you want OE-brand blades (ACDelco) or an approved third-party alternative (Bosch, Valeo, Trico) that is listed as compatible for your model.
Following these steps helps ensure you obtain the correct blade size, correct attachment, and OE-approved performance for your GM vehicle.
Summary
GM relies on a diversified mix of wiper blade suppliers. While ACDelco remains a central OE/aftermarket brand for many GM vehicles, some models and regions also use blades from Bosch, Valeo, or Trico under OEM arrangements. Since the exact supplier varies by model year and market, the best approach is to verify the blade specification for your specific GM vehicle via the owner’s manual or GM’s official parts resources, and then choose either the OE blade or an approved aftermarket equivalent.
Are Rainx or Bosch wipers better?
For consistent, long-term durability, Bosch typically takes the lead. However, Rain-X blades are an excellent choice for those who want maximum visibility in heavy rain or for drivers who value immediate, noticeable improvements in wet-weather driving.
