DENSO 210-5342 First Time Fit Remanufactured Alternator

The DENSO 210-5342 is a remanufactured First Time Fit® alternator built to original equipment specifications. DENSO alternators serve as original equipment on many of the world's top production vehicles and are a proven choice in motorsports, valued for their light weight, high efficiency, and durability under demanding conditions.

Every remanufactured DENSO alternator undergoes a rigorous multi-stage quality process before leaving the facility. Stators and rectifiers are tested to 300 volts, while rotors are subjected to 600 volts to verify reliable electrical performance. Rotor slip rings are precision-buffed to an 8-micron surface finish with runout held to 20 microns, dramatically reducing brush wear and abrasion over the life of the unit. Bearings are validated to OE standards and packed with premium OE-grade lubricants for long-term reliability.
