GM Step Motor 84131860 84452643

• Operating Voltage: 12V DC.

• High-Torque Output: Engineered with a specialized gear reduction system to provide the high stall torque needed to deploy and retract heavy-duty running boards, even when coated in mud or ice.

• Gear Construction: Features hardened steel internal gears for maximum durability and resistance to stripping under heavy loads.

• Plug-and-Play Design: Includes the weather-sealed electrical connector for a direct-fit, moisture-proof installation.

• Finish: Anti-corrosion coated housing to withstand direct exposure to road spray and debris.

• SUVs & Pickups: Widely used in Chevrolet Silverado/Tahoe, GMC Sierra/Yukon, and Cadillac Escalade (compatible with modern power assist steps).

• RV & Motorhomes: Fits various retractable step assemblies used in Class A and Class C motorhomes (compatible with systems like Lippert/Kwikee).

• Utility Vehicles: Used in modified commercial vans and accessibility vehicles requiring automated step deployment.

• GM / Chevrolet / GMC: 84131860, 84829395, 23431143

• Bosch Cross-Ref: 0130821324 / 0130822 series (Actuator variants)

• Aftermarket Refs: Compatible with several major power running board motor assemblies.

• Heavy-Duty Endurance Testing: Validated for over 100,000+ deployment cycles to ensure the motor can handle daily use in commercial and recreational settings.

• IP68 Waterproof Rating: Every motor features an airtight, vacuum-tested seal to prevent water, road salt, and grime from entering the housing—a leading cause of failure in OE motors.

• Extreme Load Simulation: Tested against resistance to ensure the motor’s safety-stop functionality works correctly while still providing enough power to clear obstructions.

• 100% Quality Inspection: Each unit undergoes an End-of-Line (EOL) test to verify torque consistency, speed, and current draw before leaving our ISO-certified facility.
