Mitsubishi Electric Heavy Duty Relays

Quality Starters Deserve Quality Relays from Mitsubishi Electric® Heavy Duty.

Long-lasting Mitsubishi Electric® Heavy Duty relays are offered as starter repair parts, but they rarely fail unless dropped, mis-threaded, wired incorrectly or fall victim to severe corrosion. It’s good to keep a supply of genuine OE replacement relays on-hand to get your truck back on the road.
