At Sixity Auto, authenticity isn’t a claim - it’s a requirement. We sell only genuine OEM and aftermarket parts sourced directly from manufacturers or their authorized distribution partners. We do not sell counterfeit, imitation, or unauthorized products - ever.
Sixity Auto is an authorized seller for the brands we carry, and many of those manufacturers publicly list us on their websites as an approved retailer.
We work directly with leading manufacturers and official distributors to ensure every part we ship is authentic and traceable.
Where available, you can verify our authorization directly on manufacturer websites. If a manufacturer does not publish public authorization lists, we maintain written authorization and sourcing documentation on file. Here is a sampling of manufacturers featuring their partnership with Sixity Auto:
