DENSO 210-5316 First Time Fit Remanufactured Alternator

The DENSO 210-5316 is a remanufactured alternator built to DENSO's exacting First Time Fit standards — engineered to mount correctly and perform reliably from the moment of installation. DENSO alternators serve as original equipment on many of the world's leading production vehicles and are trusted in motorsports for their light weight, high efficiency, and durability under demanding conditions.

Every remanufactured DENSO alternator undergoes a rigorous validation process before leaving the facility. Stators and rectifiers are tested to 300 volts, while rotors are subjected to 600 volts to confirm reliable electrical performance. Rotor slip rings are precision-buffed to an 8-micron surface finish with runout held to within 20 microns, reducing brush wear and extending service life. Bearings are validated to OE standards and packed with premium OE-grade lubricants.
