31MT™: Clean, Efficient and Reliable

The Delco Remy 31MT continues to prove why it’s the boss for medium-duty applications.

With 10% more peak power than the competition, the 31MT is both durable and reliable for applications that have lots of starts and stops or work in a variety of stressful driving conditions.

This robust starter, like all genuine Delco Remy models, is the same OE quality that customers have come to trust and count on. And there are many reasons to trust the 31MT:
  • Positive shift engagement system that provides a predictable start every time
  • Corrosion-resistant features— stainless brush springs, brush and plated brush holder—that help eliminate failures due to corrosion
  • Zero click-no-crank performance, which ensures reliability and a longer service life
  • Compact design that is powered to satisfy larger engines
  • Silicon lamination armature for better starter performance
  • Enhanced commutator and O-ring bearing for greater starter durability
