Some free car parts catalogs are the JC Whitney parts catalog, the Car-Part.com parts catalog and the Toyota Parts Direct catalog, all of which are available online. You can search or browse through these online catalogs by year, make of vehicle or OEM part number.
If you want a copy of a car parts catalog mailed for free to a physical location, request parts catalogs by contacting companies such as 4 Wheel Parts, Speedway Motors and JC Whitney. 4 Wheel Parts sends your choice of any two parts catalogs free of charge. Speedway Motors, however, only allows you to choose a single parts catalog to be mailed for free.
