Quality-Built 1003-1990M QB Premium Remanufactured Alternator

The Quality-Built 1003-1990M is a QB Premium remanufactured alternator engineered to meet or exceed original equipment (OE) specifications. Produced by Motor Products International (MPA) — the largest remanufacturer of import starters and alternators in North America — this alternator is built to deliver dependable charging performance with every turn of the key.

Unlike a typical rebuilt unit that may reuse worn components, the QB Premium remanufacturing process replaces every wear-prone part with new components, ensuring long-term reliability without the uncertainty of a basic rebuild.

Key Features:

• 100% new wear components — brushes, bearings, and springs replaced regardless of condition
• Electronically tested rotors sealed with high-dielectric insulation coating for maximum durability
• New premium brushes (lead-free) for optimum performance and extended service life
• New premium bearings with high-temperature grease to reduce heat and friction
• Electronically tested stators for maximum insulation quality and phase balance
• 100% load-tested rectifiers to ensure charging performance and alternator durability
• OE-quality terminals with high-temp insulators for secure, reliable connections
• Blasted-clean housings with inspected and re-tapped mounting threads for easy installation
• 100% plated or powder-coated pulleys for maximum corrosion protection
• Manufactured in ISO/TS 16949 certified facilities using Durability Testing, Root Cause Analysis, and Lean Manufacturing principles

The Quality-Built 1003-1990M alternator is end-of-line tested before shipment to ensure every unit meets strict performance standards. It is backed by Quality-Built's technical support hotline staffed by ASE-certified master technicians.
