They all spec dependable Mitsubishi Electric Heavy Duty® starters as their OE standard and you can too. Be sure to specify Mitsubishi Electric Heavy Duty® starters on your next new truck. When you need aftermarket starters, you’ll find Mitsubishi Electric® Heavy Duty products conveniently available for nearly every HD truck engine built since 1998. Most important, you’ll also get the hassle-free, peace-of-mind protection of the Diamond Gard® 3-year, unlimited mileage warranty. If one of our products fails ─ for any reason ─ we pay. No denials.
