Detailed description

WAI engineers this starter to deliver the amp output needed by modern vehicles, with proprietary components and manufacturing processes focused on service life and consistent performance. The 6660N is a direct-fit starter for specific Chevrolet Kodiak, Chevrolet T6500, GMC Topkick, and GMC T6500/T7500 applications that require the 10-tooth overcrank setup. If you are replacing a worn starter on a Chevrolet C6500 Kodiak, Chevrolet C7500 Kodiak, or GMC C7500 Topkick, this part number 6660N matches the listed configuration requirements.

This part cross-references AMS Automotive 6660 for the same application.

What it is used for

• Slow or inconsistent engine cranking
• Starter failure from worn internal components
• Incorrect gear engagement on the listed overcrank setup
• Replacement needs for clockwise-rotation starter applications

Installation notes and tips

Verify the 10-tooth overcrank specification, clockwise rotation, and DELCO family match before installation. Confirm the vehicle application against the fitment list for Chevrolet and GMC medium-duty trucks. The 6660N part number should be matched to the original starter configuration to avoid engagement or rotation mismatch.
