“Sixity Powersports helps diehard ATV, motorcycle, and snowmobile riders find affordable—and awesome—replacement parts for their machines.”

Breakthrough All-Terrain and Severe-Duty Axles

Our story begins in 2006 when two brothers launched Sixity by selling powersport parts out of a storage unit. Continuing as a family-owned, customer-centric company, we revolutionized the powersport industry with our all-terrain and severe-duty ATV axles and high-quality motorcycle/ATV brake pads featuring fade-free stopping power sold on eBay, Amazon, and, here, on Sixity.

Expanding into Auto Parts from the Best Brands in the World

After expanding into third-party brands like NGK, DENSO, Gates, and Dayco, we turned our sights to the automotive aftermarket, developing a line of automotive replacement parts including Sixity Wheel Spacers and Sixity Lift Supports now sold on Sixity Auto.

Positive Feedback from 350,000+ eBay Reviews

Recently, the Sixity brand became part of Proximity Group, an American-owned manufacturer and online retailer (and proud member of the Better Business Bureau). For 10+ years, we have focused on delivering value and service to our customers, garnering over 99% positive feedback spanning 350,000+ eBay reviews.
