ACI Window Regulators: Decades of Door System Expertise
When a power window stops responding or a manual crank loses its grip, the window regulator is almost always the culprit. Few brands have spent more time mastering this specific repair than ACI (Automotive Components Inc.). For over 50 years, ACI has been a pioneer in the development of window lift components for both the OE and automotive aftermarket, establishing itself as an industry leader in providing one of the most complete product offerings combined with best-in-class quality. That depth of experience translates directly into the reliability and precision that technicians and DIYers expect from a window regulator replacement.
Power and Manual Regulator Options
ACI's window regulator lineup covers both power and manual applications, available in cable and rigid — or scissor — designs. This matters because the mechanism type affects how a failure presents and what needs to be replaced. All power window regulator parts are direct replacements for the original equipment regulators, and the regulator-only format has become a more economical way to repair power window problems by allowing you to replace only the failed component.
For those who need a complete solution, ACI also offers combined motor-and-regulator assemblies. ACI window regulators are designed to exacting automaker dimensions and feature an advanced design for longer lifespan, while ACI window lift motors fit the factory-installed electrical assembly with great precision.
Engineered to Perform, Built to Last
What sets ACI regulators apart is the attention to internal engineering details that most drivers never see until something fails. ACI window motor and regulator assemblies are designed for advanced torque and speed, feature a circuit breaker to prevent overheating, and use a hardened steel gear — all characteristics that contribute to long-term durability under the repeated stress of daily window operation.
ACI Automotive customers can expect high-quality products that always undergo the necessary testing, validations, and inspections before leaving production facilities, while adhering to strict ISO certifications. ACI is currently a division of Standard Motor Products, based in Lewisville, Texas, lending the brand further engineering resources and supply-chain reliability.

ACI Automotive manufactures a considerable line of automotive door and window products, including replacement window regulators, window lift motors, switches, door lock actuators, and more. This broad product ecosystem means that when you source your window regulator from ACI, you're working with a manufacturer that understands how every component in the door system interacts — and designs its parts accordingly.
