O'Reilly Auto Parts, now combined with CSK Auto, is the third largest auto parts retailer in the US. O'Reilly Automotive, Inc. was founded in 1957 by the O'Reilly family and is one of the largest specialty retailers of automotive aftermarket parts, tools, supplies equipment and accessories in the United States. With more than 1900 locations in 26 states, our underlying spirit and philosophy is now, and has always been one of growth and progess, both for the company and for our team members. This remains the policy to which we are dedicated today. CSK Auto is the largest specialty retailer of auto parts and accessories in the western US and operates approximately 1350 retail locations in 22 states under four brand names:Checker Auto Parts, Schuck's Auto Supply, Kragen Auto Parts and Murray's Disount Auto Stores. The combination of O'Reilly's midwestern and southeastern foothold, along with CSK's dominance in the western US, has created a stronger, more competitive company that benefits not only the do-it-yourself customer, but also the professional installer. With even greater buying power and a larger team that's focused on meeting the needs of our valued customer, we will be able to offer the best combination of inventory, availability, quality, service and the most competitive prices.
