Quality-Built 146-26181 Heavy Duty Remanufactured Alternator

The Quality-Built 146-26181 is a heavy-duty remanufactured alternator engineered to meet or exceed original equipment (OE) specifications. Designed for applications that demand increased electrical output and long-term durability, this HD alternator delivers reliable charging performance under the toughest operating conditions.

Quality-Built remanufactures each alternator to exacting standards, replacing every component prone to wear with new parts — including brushes, bearings, and rectifiers — rather than simply cleaning and reassembling worn components like a typical rebuilt unit. All units are end-of-line tested to ensure consistent output and reliability before leaving the facility.

Key Features:

• Heavy-duty (HD) construction for high-demand electrical systems
• Remanufactured to OE specifications or better for a direct-fit replacement
• Rotors electronically tested and coated with high-dielectric insulation for maximum durability
• 100% new brushes and springs for extended service life and consistent charging performance
• Bearings inspected or replaced new, packed with high-temperature grease to reduce heat and friction
• Stators electronically tested for insulation quality and phase balance
• Rectifiers 100% load-tested to ensure alternator durability and charging output
• Housings blast-cleaned; all mounting threads inspected and re-tapped for easy installation
• OE-quality terminals with high-temp insulators for secure, reliable connections
• Pulleys plated or powder-coated for maximum corrosion resistance
• Manufactured under strict QS-9000 quality guidelines

The Quality-Built 146-26181 heavy-duty alternator is an ideal solution for vehicles with elevated electrical demands, providing dependable charging performance and a direct OE-style fit.
