The Quality-Built 10339 is a remanufactured premium alternator from Quality-Built's MPA line, engineered to meet or exceed original equipment (OE) voltage and amperage specifications. Manufactured under strict ISO/TS 16949 and QS-9000 quality guidelines, this unit delivers the reliable charging performance that professional installers and DIY mechanics demand.

Key Features:

• 100% End-of-Line Tested: Every unit is performance-tested before shipment to ensure reliability and durability right out of the box
• All Wear Components Replaced: Brushes, springs, bearings, and diodes are replaced with new parts — not reused worn components
• Precision-Polished Slip Rings: Ensures maximum electrical contact and smooth, stable voltage output across all RPMs
• High-Capacity Diodes: Press-fit diodes with increased surface area for faster heat dissipation and a longer service life
• Double-Coated Rotor and Stator: Electronically tested and coated with high di-electric insulation for corrosion resistance and maximum charging performance
• 100% Voltage Regulator Tested: Ensures correct operating voltage and prevents voltage spikes or arcing
• OE-Spec Pulley: Plated or powder-coated for corrosion protection and proper belt engagement
• Re-Tapped Mounting Threads: Housings are blasted clean and all mounting threads are inspected and re-tapped for easy, consistent installation

Quality-Built alternators are remanufactured using proprietary processes developed by Motorcar Parts of America (MPA), the largest remanufacturer of import starters and alternators in North America. Each unit undergoes Durability Testing and Root Cause Analysis to identify and correct failure points before the product ever reaches the customer. The result is a remanufactured alternator that performs with the confidence of a new unit.
