About

RockAuto is an online-only auto parts retailer founded in 1999 in Madison, Wisconsin by the Taylor family. Unlike traditional brick-and-mortar auto parts chains, RockAuto operates exclusively through its website, which allows the company to maintain lower overhead and pass savings to customers. The company is privately held and has grown to become one of the largest online auto parts retailers in the world, shipping to customers in all 50 US states and over 150 countries.

RockAuto's catalog contains parts for cars, trucks, SUVs, and vans from hundreds of manufacturers, ranging from economy-grade to premium OEM-equivalent components. The website features a distinctive catalog-style interface organized by vehicle year, make, and model, with detailed part diagrams and cross-reference numbers. RockAuto is known for its competitive pricing and wide parts availability, particularly for older and less common vehicles that brick-and-mortar stores may not stock.

RockAuto is the price leader in online auto parts retail, and for shoppers who know exactly what they need, the savings over brick-and-mortar stores and even other online retailers can be substantial. The catalog covers virtually every domestic and import vehicle with comprehensive part listings organized by vehicle and system. The no-frills website design is intentional -- minimal overhead means lower prices. The 30-day return window is standard. However, the trade-offs for low pricing are real: no free shipping means calculating total cost carefully, customer service is minimal, and there is no loyalty program. The website deliberately avoids the hand-holding that newer shoppers might need. Returns can be cumbersome with restocking fees in some cases. RockAuto is the clear choice for experienced DIY mechanics who prioritize price above all else and do not need purchasing guidance or immediate availability.
