Great cars and trucks like your K3500 need great parts.

Select Your VehicleIt's not a regular occurrence that you realize that you have to buy a replacement Relay to repair your automobile. When your GMC K3500 was born, it was destined for a person with discerning taste who values longevity in their automobile. Make no mistake, you didn't buy your K3500 unless you knew that you wanted horsepower and rugged design both rolled up into one vehicle. While it may not be difficult to locate replacement parts for GMC vehicles, these days only the absolute best are required to repair your car or truck.

Don't go too long without fixing your Relay... here's why.

A relay represents a switch that can be used electrically. Electromechanical relays are the most common ones on the market. They do their job by making use of electromagnets that put into motion the entire set of contacts to make or break circuits. Relays also help you to perform your GMC K3500 logical car functions and inputs. If your GMC K3500 doesn't start when you activate the ignition, and if the engine light doesn't switch "ON" and "OFF", it is an indication that the main relay is broken. You can repair it, or buy a new one in case you prefer a faster solution.

Time has come... make your purchase while supplies last.
