Bosch SR578X Professional Preferred Remanufactured Starter Motor

The Bosch SR578X is a Professional Preferred Remanufactured Starter Motor engineered to deliver reliable, OE-level starting performance. As part of Bosch's remanufactured starter line, the SR578X is built to withstand extreme heat, cold, and high electrical demand — making it a trusted replacement for worn or failed original equipment starters.

Unlike rebuilt units, each Bosch remanufactured starter is fully disassembled, cleaned, and remanufactured using the highest-quality materials and the most technologically advanced processes available. Every component is 100% factory-tested both prior to and during the remanufacturing process to ensure the finished unit meets or exceeds original equipment specifications.

Key Features:

• Remanufactured, not just rebuilt — each unit is fully remanufactured to exacting OE standards
• 100% factory tested — tested before and during remanufacturing to meet or exceed OE specs
• Extreme-condition rated — engineered for reliable operation in extreme heat, cold, and high-demand environments
• Premium lubrication — all shaft splines and load-bearing surfaces lubricated with OE-spec high-temperature grade lubricant
• Armature quality control — armature continuity is tested, gauged, straightened, and shimmed for precision performance
• Direct OE replacement — designed for a precise fit with no modification required

The Bosch SR578X remanufactured starter is ideal for professional technicians and DIY mechanics seeking a dependable, cost-effective alternative to a new OE starter without sacrificing quality or reliability.
