  • Introduction
  • factory
TinzerMotor Power Step Motor: 84131859
TinzerMotor is a premier manufacturer of high-torque actuation solutions. Our 84131859 Power Step Motor is specifically engineered to provide rugged, reliable deployment for electric running boards on RVs, SUVs, and Pickup Trucks, where strength and environmental resistance are critical.
1. Technical Information
  • 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.

  • Rotational Direction: Left Hand (LH) / Driver Side (often paired with the 84131860 RH model).

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

2. Applications
The 84131859 is a high-performance replacement motor for electric step systems in:
  • SUVs & Pickups: Widely used in Chevrolet Silverado/TahoeGMC Sierra/Yukon, and Cadillac Escalade (2015-2020+ models) equipped with power assist steps.

  • RV & Motorhomes: Fits various retractable step assemblies used in Class A and Class C motorhomes.

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

3. Interchange Numbers (Cross-Reference)
The TinzerMotor 84131859 is a direct replacement for:
  • GM / Chevrolet / GMC: 84131859, 84829394, 23431142

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

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

4. TinzerMotor High Quality & Testing
At TinzerMotor, we understand that a power step motor lives in the harshest environment under the vehicle. Our quality assurance includes:
  • 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—the primary cause of failure in OE motors.

  • Extreme Load Simulation: Tested against high resistance to ensure the motor provides enough power to clear obstructions while maintaining safety-stop functionality.

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