Mechman 400A Alternator for GM Suburban Tahoe Silverado Escalade

The Mechman 400A Alternator is a top-tier replacement for your GM Suburban, Tahoe, Silverado, or Escalade. Engineered with cutting-edge 6-phase technology, this alternator ensures robust performance and reliability. It boasts a massive twin rectifier assembly and 12 diodes, making it perfect for daily use without compromising on amperage output at idle speeds.
  • High Amperage Output: Maintains 200+ amps at engine idle speeds for consistent power supply.
  • Custom Built to Order: Standard build time of 10-14 days ensures a perfect fit and performance.

Product Specifications and Technical Details

This alternator comes with a smaller 1.75-inch diameter pulley, requiring a shorter drive belt for proper belt tension. It is not recommended for sustained use above 5,000 RPM to avoid overloading. The Elite series alternator offers the highest possible amperage and durability in a large case alternator. It uses a more robust 4-pin style regulator, bypassing the RVC charging system for smoother voltage fluctuations and eliminating the check battery light issue.
  • Smaller Pulley and Shorter Belt: Ensures proper belt tension and optimal performance.
  • 4-Pin Regulator: Provides stable voltage output and improved reliability.

Practical Uses and Benefits

The Mechman 400A Alternator is an ideal choice for those who demand the best from their vehicles. It is suitable for a wide range of GM vehicles, including Buick Rainier, Cadillac Escalade, Chevrolet Avalanche, Suburban, Tahoe, Silverado, and GMC Sierra. This alternator ensures a consistent power supply for your vehicle's electrical systems, including lights, power windows, and audio equipment, even under demanding conditions.
  • Wide Vehicle Compatibility: Fits various GM models from 2005 to 2013.
  • Enhanced Electrical System Performance: Powers your vehicle's electrical systems reliably, improving overall functionality.
