Denso Reman Starter for GM Trucks and SUVs

Denso Reman Starter 280-5389 is a 12-volt, clockwise-rotation starter built for GM and Saab applications that need dependable cranking performance. With a 1.7 kW power rating, it is a direct-fit replacement for a wide range of Chevrolet, GMC, Cadillac, Hummer, and Saab vehicles from 2006-2009.

The Denso remanufactured starter line focuses on OE-style fit and consistent electrical performance. This unit is bench-tested after remanufacturing, with high-voltage testing of the armature and field coils, refinished commutators, and replacement of wear items such as bearings, brushes, and seals.
