The Delco Remy 39MT™ Heavy Duty Starter with Smart IMS is a gear reduction starter ideal for heavy duty truck and off highway applications. The drive has an electrical soft start that rotates the pinion for proper ring gear engagement before cranking, minimizing tooth abutment related damage. The sealed solid link solenoid eliminates contact welding in low system voltage situations, providing enhanced reliability. Sealed noiseless configuration minimizes debris accumulation and contamination reducing maintenance expense.
