Heavy Duty 12V Starter Motor

Optimized Fitment for Postal Vehicles & GM Passenger Cars

Restore the reliability of your vehicle's ignition system with this premium aftermarket starter motor. Specifically engineered to meet or exceed OEM specifications, this unit is a critical component for the high-demand "stop-and-start" cycles common in postal delivery vehicles and classic General Motors daily drivers.

Utilizing an Offset Gear Reduction (OSGR) design, this starter provides superior torque while drawing less current from your battery. This ensures fast, crisp engine engagement even in cold weather or high-compression environments, making it a dependable choice for both commercial and personal use.

DIRECT FIT / KEY SELLING POINT: Engineered as a direct drop-in replacement for Denso 428000-1820, ensuring no modifications are required for installation in Grumman LLV postal trucks and compatible Buick/Chevrolet models.

Key Features

  • High-Torque OSGR: Delivers 1.4KW of cranking power for reliable starts.
  • Sealed Construction: Internal components are protected against moisture and residue.
  • Premium Brushes: High-quality copper and silver contacts for improved conductivity.
