About Quality-Built
Quality-Built, the flagship brand of Motorcar Parts of America (MPA), has earned a strong reputation as one of the aftermarket industry's most trusted names in replacement automotive components. Quality-Built parts are engineered specifically to meet the demands of professional installers — technicians who simply cannot afford a comeback job. From its beginnings focused on rotating electrical parts, the brand has grown into a broad portfolio that includes brake system components, wheel hub assemblies, and more.
Engineering & Quality Standards
What sets Quality-Built apart is a relentless commitment to process-driven quality. Quality-Built alternators and other components are 100% End-of-Line tested before leaving the factory, meaning every single unit is verified for performance — not just a sample. Manufacturing takes place exclusively in IATF-16949 certified facilities, the same international quality management standard used by original equipment suppliers to automakers worldwide.
MPA's in-house Innovation Center operates around the clock, deploying proprietary computer-controlled testing equipment designed and built by MPA's own engineering team. Root-cause analysis is performed on returned parts to identify failure modes, and engineering solutions are developed to prevent recurrence — a continuous improvement loop that benefits every unit that ships.
Remanufacturing & Sustainability
Quality-Built has long been a pioneer in responsible remanufacturing. By refurbishing and re-engineering cores rather than producing entirely new parts, the process conserves a remarkable amount of energy compared to traditional manufacturing — reducing material and energy consumption by up to 91%. This approach doesn't just benefit the environment; it also allows MPA to study real-world failure patterns from returned cores and apply those findings to produce even more durable finished units.
Support & Coverage
One of Quality-Built's most valued differentiators is its Part-Smart program — a free, live support network staffed by ASE-certified technicians. Whether a shop needs installation guidance, technical bulletins, or product clarification, Part-Smart provides answers in real time. Combined with one of the most comprehensive warranty programs in the aftermarket, Quality-Built delivers genuine peace of mind alongside the part itself.
From replacement alternators that meet or exceed OE output specs to brake master cylinder reservoirs engineered for precise fluid management, Quality-Built covers a wide range of vehicle applications for cars and light trucks. With thousands of SKUs and broad application coverage, it's a go-to brand for professional shops and serious DIYers alike.
