Quality-Built 10428 Remanufactured Premium Alternator

The Quality-Built 10428 is a QB Premium remanufactured alternator engineered to meet or exceed original equipment specifications. Unlike standard rebuilt units that may reuse worn components, every wear-prone part in this alternator is replaced with a new component during the remanufacturing process — regardless of the condition of the original part.

Key Features:

• 100% new wear components — brushes, springs, and high-temp insulators replaced on every unit
• Electronically tested rotor — coated with high dielectric insulation for maximum durability and charging performance
• Electronically tested stator — verified for maximum insulation quality and phase balance
• Load-tested rectifier — ensures long-term alternator durability and consistent charging output
• Precision-polished slip rings — optimized for maximum output and minimal wear
• Voltage regulator tested — verified for correct operating voltage before leaving the factory
• Corrosion-resistant pulleys — plated or powder coated for extended service life
• OE-quality terminals — 100% inspected with high-temp insulators for secure, reliable connections
• Blasted and re-tapped housing — all mounting threads inspected and re-tapped for easy installation and consistent torque
• Manufactured under strict QS-9000 quality guidelines — the highest quality standard for automotive parts suppliers

Quality-Built alternators are a product of Motor Car Parts of America (MPA), one of the world's largest remanufacturers of import starters and alternators. Each unit undergoes comprehensive durability testing and root cause analysis at MPA's Technology Center to ensure reliable, long-lasting charging performance in everyday driving conditions.
