Sixity Auto, with its 20+ years of service, is a recognized name in the auto parts industry. We’ve built a reputation for transparency, affordability, and accessibility. Every part in our inventory meets rigorous specifications, ensuring performance and accurate fit. Because our products are OEM-quality and not OEM parts, our prices are much lower than you’ll find at your local dealership or auto parts store. Also, being an online retailer means we can offer a larger selection of products than most local sellers.

Because we operate as an online retailer and source high-quality aftermarket parts rather than dealer-branded products, we can provide significant savings. See, brick-and-mortar auto parts stores must increase costs to cover operational overhead. Our setup means we have relatively low overhead, resulting in fewer markups.

100%. We only inventory the brands we’d trust with our own vehicles. Every brand has certifications proving performance and fitment. Beyond the documentation from brands, you can also bank on our reputation and 20+ years of industry experience.
