Rated for over 50,000 starts, I’m told, the new Bosch SR5065LH ‘Long Haul Commercial Starter’ is claimed to offer twice the life of older starters, along with lighter weight for ease of installation.

Features include six-pole field windings for increased power with less sensitivity to low battery charge for more reliable starts; a planetary gear reduction system to increase torque and provide faster starts; O-rings to increase resistance to dust, dirt, and moisture, thereby increasing life; a weight of only 21 lb, said to be as much as 38% lighter than comparable units; a two-stage solenoid that prevents damage to the engine ring gear and extends the life of the starter pinion gear; and conical solenoid contacts, dual-composite ‘long life’ brushes, and an integral magnetic switch that should provide quicker starts and increased durability
