Where the facts come from

Product facts (what is in the box, the material, the model years and bodies a part fits, how it installs) come from our own product descriptions. Prices come from our scheduled catalog update.

Public sources

Our guides lean on public agencies and national organizations: NHTSA, the U.S. Department of Transportation, the Federal Trade Commission, the Electronic Code of Federal Regulations, the Governors Highway Safety Association, the National Safety Council, AAA and the AAA Foundation for Traffic Safety. Every source is opened and read before a sentence cites it, and the date we read it is printed with it. No agency approves or endorses our parts.

Photos

Product photos show our own parts, fitted to the trucks they are made for or laid out on their own. Where a photo of ours carried words or graphics, the page shows the part of the photo without them.

Ratings

The star rating and the number of ratings on a product come from shoppers at our retail partner, as of our last update. Options of one product share a pool of ratings, and we count each pool once.

Corrections

If you find a mistake, write to garage@mabett.org. We fix facts first and note the change in the next catalog update.
