New Auto Parts
New focuses on an unused replacement component. Manufacturer, source, included pieces, and OEM status should still be confirmed separately.
New replacement-part sourcing
New Auto Parts Sourced Across the USA
Request a new replacement component using the exact vehicle, fitment, and destination details. Doorstep Auto Parts reviews available sourcing options for cars, trucks, and SUVs across the USA.
Condition and source
What “new” means when sourcing an auto part.
A new auto part generally refers to a replacement component that has not previously been installed or used as a service replacement. The exact packaging, manufacturer, distribution source, and included pieces can vary by component.
New does not automatically mean OEM. OEM identifies the original-equipment manufacturer or specification, while new describes condition or prior-use status. A new component may be OEM or non-OEM depending on the request and available source.
Doorstep Auto Parts confirms the available condition, source, manufacturer information, included pieces, and other relevant details during the sourcing process. Availability depends on the exact vehicle and component.
Condition and identity
New, used, and OEM describe different things.
The right sourcing direction depends on the repair, vehicle, component, and information confirmed for the specific option.
Used Auto Parts
Used components have previously been installed and may include recycled or salvage-sourced assemblies matched to the vehicle.

Questions about new auto parts.
Confirm the exact condition, manufacturer, source, included pieces, and application for any option discussed.
Are all new auto parts OEM?
No. New describes the condition or prior-use status of a replacement component. OEM describes its manufacturer or original-equipment identity. A new option may be OEM or non-OEM, so confirm both details separately during sourcing.
Can I request a new part for an older vehicle?
Yes. Submit the vehicle and component details for review. Whether a new replacement option can be sourced depends on the exact application, component, and available sources at the time of the request.
What information helps match a new replacement part?
Provide the year, make, model, VIN when available, part name, original identifiers, and relevant details such as engine, drivetrain, body style, trim, position, or connector configuration.
Can Doorstep confirm whether a new option is available?
The team reviews the submitted vehicle and component information, checks available sourcing options, and contacts you with relevant details. The website does not display live availability.
Do new parts come directly from a dealer?
Not necessarily. The source and manufacturer can vary by component and request. Ask the team to confirm the source, condition, manufacturer, and OEM status of any option discussed.
