Prestolite PowerPro Extreme 12 Starters from Leece-Neville have an even higher level of dependability and performance through iRelay (intelligent relay) technology that provides programmable protection features that are fully customizable to OEM requirements, for both single and dual starter applications, as well as added protection against early life failures caused by a range of cranking issues, pinion and ring gear tooth abutments, and more. A standard SW030 starter control relay with an added electronic module provides programmable “intelligent” protection using small microprocessors. PowerPro Extreme 12 starters feature 24V, 12kW starting power ideal for diesel engines up to 40L in single configuration, up to 85L in dual configuration, and above 90L in triple configuration.
