WAI 6757N Starter

Starter for Delco PMGR Applications

The WAI 6757N starter is a 100% new unit built for vehicles that need reliable amp output and consistent cranking performance. It uses a permanent magnet gear reduction design with a clockwise rotation and 11-tooth drive for Delco-style applications.

Compatible With 2006-2009 GMC Sierra 3500 HD, 2006-2008 Cadillac Escalade, and other listed GM trucks and SUVs, this starter is built around the fitment and electrical requirements of late-model GM platforms. The WAI 6757N is a direct replacement option for drivers servicing starting-system issues on Chevrolet Silverado, GMC Yukon, and related applications.

• Permanent Magnet Gear Reduction design for efficient starter operation
• 100% new construction, not remanufactured
• Clockwise (right) starter rotation
• 11-tooth drive for Delco PMGR applications
• 1.4 power rating
• Pad mounting type
• Built for 12-volt electrical systems

Detailed Product Overview

WAI engineers this starter to deliver the amp output needed by today’s vehicles while maintaining consistent engagement in Delco-family applications. The 6757N part number is associated with a permanent magnet gear reduction starter configuration, making it a practical replacement for GM trucks, SUVs, and vans listed in the fitment data. If you are searching for a starter for a 2006 Chevrolet Silverado 1500, 2008 GMC Yukon XL 2500, or 2008 Chevrolet Tahoe, this unit matches the specified rotation, tooth count, and mounting style.

This part cross-references AMS Automotive 6757 for the same application.

Installation Notes and Tips

Verify the vehicle’s starter rotation, tooth count, mounting type, and electrical system before installation. This starter is listed for Delco PMGR, 11-tooth applications, so matching the original unit specifications is important for proper fitment. Confirm the application against the vehicle’s year, make, and model, especially on Silverado, Sierra, Escalade, and Yukon platforms where multiple starter configurations may exist.
