Denso starters are so rugged and powerful they are often adapted for racing use. 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 to ensure reliable performance. Commutators refinished and performance validated. Terminals and fasteners replaced with high quality copper components to ensure a clean source of electrical current. Maximum cranking torque under all conditions.
