Founded in 2006 by two brothers, Sixity began as a small venture selling powersport parts out of a storage unit. Today, it has grown into a trusted name in the powersports and automotive aftermarket industry. Known for providing high-performance ATV and motorcycle parts, Sixity offers everything from severe-duty ATV axles to fade-resistant brake pads, designed to endure the toughest conditions. Over the years, Sixity expanded its product range, introducing automotive parts like wheel spacers and lift supports, alongside renowned brands such as NGK, DENSO, and Gates.

Now part of the Proximity Group, Sixity continues to operate with a customer-centric focus, delivering quality products at affordable prices. The company is proud of its 99% positive feedback across over 600,000 eBay reviews, reflecting its commitment to excellent service. Sixity’s core values include fast and free shipping, a 100% fitment guarantee, and a U.S.-based customer service team, ensuring a seamless shopping experience for its value-conscious customers. All Sixity-branded parts come with a limited 1-year warranty, offering peace of mind for every purchase.
