About Us
Promotions & Rebates

RockAuto is an online, family business founded in 1999 by automotive engineers with two goals:

  • Liberate information hidden behind the auto parts store counter (by listing all available items and product specifications on, not just what one store stocks or one counter-person knows)
  • Make auto parts affordable (by remaining a strictly online company, we have no store locations, no counter-people and don't have a lot of money tied up in slow-moving inventory. We pass on those savings with lower prices so cars of all ages can be reliable and fun to drive.)

Today, we ship thousands of parts, from hundreds of manufacturers, to millions of customers all over the world. And the RockAuto catalog keeps expanding. Someday, it may be possible to build an entire car using parts from RockAuto!
