REMAN (REMANUFACTURED)

Delco Remy Reman Starters and Alternators Ideal Solution for Older Trucks


If you have older trucks in your fleet—trucks that are outside warranty—you are likely looking for cost-effective ways to handle repairs when they arise. While non-OE (original equipment) remanufacturers, local rebuilders and coreless whitebox productsmay be lower priced, these aftermarket options are actually more prone to problems and failure.

These ‘value’ or offshore products are not made from OE components—or to OE specifications, they use aftermarket parts and are often unreliable. You may get a better deal upfront—but chances are you’ll pay for it when your truck is stranded on the side of the road or in the shop again for repairs.”

That’s where the Delco Remy reman product line comes in.

Delco Remy reman starters and alternators incorporate OE components, processes, testing and validation—something our competitors are not able to do because they are not an OE manufacturer. 

While new service is always the best option, the reman offering is the ideal solution for buyers seeking quality starters and alternators at a lower price than new service. Our remanufacturing site is quite different—and so is the result. In a dedicated facility, we remanufacture a high volume of alternators and starters each year in a process that’s as methodical as our OE plants. In fact, the link to OE is something that can’t be found in a simple rebuild. Our OE engineers are involved in the remanufacturing process.
