TinzerMotor Power Step Motor: 800312990
TinzerMotor is a premier manufacturer of high-torque actuation solutions. Our 800312990 Power Step Motor is specifically engineered to provide rugged, reliable deployment for electric running boards on RVs, SUVs, and Pickup Trucks, where high structural strength and extreme environmental resistance are critical.
1. Technical Information
  • Operating Voltage: 12V DC.

  • High-Torque Output: Engineered with a specialized high-ratio gear reduction to provide superior stall torque, ensuring the steps deploy and retract smoothly even when obstructed by mud, ice, or road debris.

  • Gear Construction: Features hardened alloy steel internal gears and a high-efficiency copper-wound motor for maximum durability and resistance to stripping under heavy weight loads.

  • Acoustic Profile: Optimized for quiet operation (under 45 dBA), maintaining the premium feel of high-end SUVs and luxury RVs.

  • Finish: Anti-corrosion powder-coated housing protects internal components against road spray, oxidation, and chemical de-icers.

2. Applications
The 800312990 is a high-performance replacement motor for electric assist steps in:
  • RVs & Motorhomes: Specifically designed for various retractable step assemblies used in Class A, B, and C motorhomes (compatible with certain Lippert/Kwikee and Torklift systems).

  • SUVs & Pickups: Widely used in Chevrolet Silverado/TahoeGMC Sierra/Yukon, and Ford F-Series trucks equipped with aftermarket or factory power running boards.

  • Transit Vans: Fits power side-step configurations for Ford Transit and Mercedes-Benz Sprinter conversion vans.

  • Accessibility Vehicles: Utilized in specialized paratransit vehicles requiring automated step deployment for passenger safety.
