39MT 12V 12-tooth starter motor designed for high-performance engine starting in heavy-duty applications. Lightweight and compact construction supports easier installation. Delivers up to 30% increased crank speed for improved starting efficiency and reduced downtime. Features an integral magnetic switch (IMS) that reduces voltage drop and ensures maximum solenoid voltage under all starting conditions. Sealed configuration minimizes debris accumulation and contamination, enhancing durability and reliability.
