Product Details

The WAI New line focuses on fresh-built electrical components for starting and charging systems. For this application, the 17801N starter is matched to Hitachi OSGR fitments and is specified for vehicles across the Chevrolet Silverado 2500 HD and 3500 HD, GMC Sierra 2500 HD and 3500 HD, plus Express and Savana van platforms. If you are replacing a worn starter on a Chevrolet Silverado 2500 HD or GMC Sierra 3500 HD, this unit provides the correct Hitachi-style configuration and 9-tooth engagement.

This part cross-references BBB Industries 17801 and Carlson 19020 for the same application.

What It Helps Fix

• Slow or weak engine cranking
• No-start conditions caused by starter failure
• Intermittent starting after key turn
• Grinding or poor starter engagement
• Electrical starting issues on Hitachi OSGR-equipped trucks and vans

Installation Notes and Tips

Verify the existing starter’s Hitachi family, offset gear reduction design, clockwise rotation, 9-tooth drive, and flange mount before installation. Confirm the vehicle’s original equipment specification, especially on 2011 models that may reference either 1.8 kW or supplied 2.2 kW Hitachi OSGR units. Match the starter to the exact application listed for your Chevrolet Silverado, GMC Sierra, Chevrolet Express, or GMC Savana.
