Product Details

Denso remanufactured starters are rebuilt with a focus on electrical integrity, durability, and repeatable starting performance. The reman process includes testing critical internal components, replacing wear items, and validating output before the unit leaves the factory. That makes the 280-5117 a practical choice for drivers needing a reman starter for Ford Explorer, Ford Ranger, or Mazda B4000 starting-system service.

This starter cross-references Ford OE numbers such as F87U-11000-B1A and F87Z-11002-BA for the same application.

What It Helps Solve

• Slow or weak engine cranking
