Commercial Starter Solenoid

The starter solenoid (starter relay) is a key component to the electric starter. It sends power to the starter motor which, in turn, spins the engine and initiates ignition. This small piece has a crucial and vital role in your vehicle’s ignition system; without it, the electric starter is rendered useless. Failed starter solenoids are often the reason for starter failure, but the good news is that these parts can be swapped and replaced as opposed to purchasing a brand new starter. If you choose to repair your electric starter yourself or replace the entire unit, Discount Starter & Alternator is at your service. We stock brand new replacement starter solenoids and relays for commercial trucks, vans, buses, tractor trailers, and other heavy duty work vehicles from major manufacturers including Chevrolet, Freightliner, GMC, Isuzu, and more.
