What Are New Units and Exchange Services?

A new unit is exactly what it sounds like—a brand-new starter or alternator, straight from the manufacturer. These are ideal for customers who want the latest components with full warranties.


An exchange unit is a rebuilt starter or alternator that’s been restored to like-new condition. You bring in your old unit (called a “core”), and we give you a rebuilt one at a lower price. It’s fast, affordable, and eco-friendly.

Why Choose an Exchange Unit?

Exchange services are a smart choice for many customers. Here’s why:

Lower Cost

Rebuilt units cost less than new ones, without sacrificing performance.

Quick Turnaround

No waiting for repairs—just swap and go.

Eco-Friendly

Reusing cores reduces waste and conserves materials.

Tested for Quality

Every rebuilt unit is tested to meet or exceed OEM standards.
