DENSO Starters and Alternators are manufactured and tested to the strictest OE specifications for unparalleled performance. With over 60 years of experience in supplying the automakers with premium electrical components, DENSO has the inside track on starter technology.


DENSO has an inside track on starter technology. The original DENSO gear-reduction starter is an industry benchmark, so rugged and powerful that it is often adapted for racing use. DENSO remanufactured starters are subjected to a rigorous test and replacement routine that produces the lowest return rates in the replacement aftermarket. Armatures and field coils are high-voltage tested; commutators are refinished and performance validated; terminals and fasteners are replaced with high-quality copper components. And every starter is exactingly bench-tested to ensure factory-original performance.
