2016 Subaru Outback Body Actuators and Motors

What Are Body Actuators and Motors?

Body actuators and motors are the electrically driven mechanical components responsible for applying force, motion, and precision control to critical vehicle systems. From holding your vehicle securely on a hill to maintaining consistent brake boost on modern hybrid and electric platforms, these parts work behind the scenes to ensure both safety and drivability. As vehicles have shifted away from purely mechanical systems toward electronically controlled architectures, the role of actuators and motors has grown considerably more complex — and more important.

Why These Parts Matter

Modern vehicles increasingly rely on electronic control rather than traditional cable and vacuum-based mechanisms. Parking brake actuators, for example, have made a major leap in prevalence: parking brake actuators now appear on tens of millions of vehicles, replacing the familiar handbrake lever with a compact motor-driven unit mounted directly at the caliper. Power brake booster pump motors serve a similarly critical role on vehicles that lack a conventional vacuum source — such as hybrids and some turbocharged platforms — by generating the pressure needed to maintain firm, predictable brake pedal feel. Even parking brake pump motors, which drive the hydraulic or electromechanical circuits in more complex parking brake assemblies, are essential links in the chain between driver input and safe vehicle immobilization.

When any component in this system begins to degrade — whether from heat cycling, corrosion, or simple wear — drivers may notice warning lights, inconsistent brake engagement, or a soft pedal. Addressing a failing actuator or motor promptly is not just a matter of convenience; it directly affects vehicle safety.

Key Considerations When Shopping

• OE vs. Aftermarket Fit: Many body actuators are highly vehicle-specific. Confirming part fitment by year, make, model, and sometimes sub-model is essential before purchasing.
• Remanufactured vs. New: Some categories offer remanufactured units that meet OE specifications at a lower cost, while others benefit from all-new construction for long-term reliability.
• System Compatibility: Electronic parking brake actuators communicate with the vehicle's ECU, so selecting a part engineered to the correct signal and torque specifications is critical for proper operation and error-free performance.
• Brand Reputation: In safety-critical applications like braking, choosing a trusted manufacturer matters. Look for parts backed by OE-equivalent testing standards.

Top Brands in Body Actuators and Motors

ACDelco is the automotive parts brand owned by General Motors, offering both OE-grade and aftermarket components across its Gold and Silver product lines. ACDelco's parts are engineered to meet GM specifications and are broadly compatible across many makes and models, making them a go-to source for precision-fit actuators and motors.

Standard Motor Products has been manufacturing and distributing automotive components since 1919, with deep expertise in electrical and electronic systems. Standard's commitment to keeping pace with advanced vehicle technology makes their parking brake actuators and related electronic components a strong choice for modern applications.

URO (distributed by A.P.A. Industries) specializes in aftermarket replacement parts for European vehicles, offering an accessible option for owners of BMW, Mercedes-Benz, and other European platforms who need actuator components outside of dealer channels.

Mopar Performance is Stellantis's factory-backed parts and performance brand, providing components engineered specifically for Chrysler, Dodge, Jeep, and Ram vehicles. For owners of FCA-platform vehicles, Mopar actuators and motors offer the peace of mind of manufacturer-validated fitment and quality.

Dorman has supplied the aftermarket since 1918 with a broad catalog of replacement parts spanning passenger cars, light trucks, and medium-duty vehicles. Dorman's OE Solutions line targets hard-to-find and obsolete components, making them particularly useful when factory parts are no longer readily available.
