Relays are found in many places of automotive electrical systems. They're useful for allowing low-amp circuits (which can be attractive for aesthetic reasons) to interact with high-amp systems, such as your car's ignition and headlight lamp switches. At StockWise Auto, you can find the right relays for each type of GMC K3500 system quickly, easily and economically.


One vital relay for your GMC K3500 is the ignition relay. It delivers power to the starter, fuel pump and other fuel system components.

When performing repairs, choose a high-quality replacement for long-term performance and driving safety.
