In the aftermarket, dealers, warehouse distributors and fleets around the world trust our starters to deliver superior cranking power and durability.

We continue to leverage our experience to provide our OE and aftermarket partners with innovative solutions for today’s vehicle electric system challenges.

Featured Product: The 39MT Starter

Shop for the starter that everyone's talking about: the 39MT Heavy Duty Gear Reduction Starter.

ELECTRICAL SOFT START

Our second-to-none redefined electrical soft start reduces overall wear-and-tear by slowly rotating the pinion until it properly engages into the ring gear, before cranking begins.

ROTATABLE FLANGE

Rotatable flange models like the 39MT are built to easily replace competitive units and provide full industry application coverage of virtually every 12-volt and 24-volt starter motor application.

OPTIMUM SPLINE

Each starter is built with the ideal number and spacing of spiral spline teeth to provide high strength and smooth engagement.

ADVANCED CIRCUITRY

The larger gauge motor circuit wire translates to higher current draw and lower voltage drop as well as a lower resistance solenoid to ensure pinion engagement to the ring gear.

Cranking Past the Competition

The Delco Remy 39MT cranks up to 30 percent faster than the competition.

The starter was compared to major competitor models like the Mitsubishi 105, the Denso R5, and the Unipoint starter motors. It resulted in a higher RPM than any of these major brands at every Engine Cranking Torque level.

OVER CRANK PROTECTION

Over-Crank Protection on the Delco Remy 39MT protects the starter in adverse starting conditions like:

  • Cold-weather Cranking
  • Lower Battery Capacity
  • High-starting Circuit Resistance
  • Operator Misuse

Over-Crank Protection (OCP) is a circuit breaker that's built in to the starter that protects it from any thermal damage by automatically resetting the starter to a safe operating temperature.

Featured Product: 40SI Alternator

Brushless Alternators are the future, and the 40SI is the best out there. Here's why:

BRUSHLESS DESIGN

Brushless alternators have fewer moving parts, which means less wear on the alternator which translates to longer part life and fewer alternator troubles.

REMOTE SENSE

Standard on the 40SI, Remote Sense reduces battery charge time by nearly 50 percent, providing the maximum amount of voltage to your battery.

IMPROVED BEARING DESIGN

The 40SI design features bearings with enhanced steel and seals that improve the overall durability and life cycle of the alternator.

UNIQUE STATOR DESIGN

The patented design of Delco Remy’s hairpin stator technology provides not only a high power output and maximum torque but reduced energy loss that results in best-in-class efficiency.

The Brushless Advantage

All alternators pull air through from the back to the front in order to cool the internal electronics. This causes dust to enter into the alternator. However, with a brushless alternator, it eliminates any issues of dust clogging up the brushes and causing early failure. With this design, there are 13 fewer moving parts, many of which consistently wear out, meaning overall product life is extended.

Problems you won't see again after switching to a brushless alternator:

  • Stuck, Broken or Worn-out Brush
  • Corroded or Shorted Slip Ring
  • Broken Brush Springs or Shunts
  • Grounded Rotor Coil
  • High Turn-On

Breaking Down the Benefits of Remote Sense

With a normal alternator, the resistance in charging cables caused by environmental factors and other conditions will result in a drop in voltage from the alternator by the time it reaches the battery. Just because the alternator is sending 14 volts doesn’t mean that the battery is receiving 14 volts. Enter Remote Sense.

With Remote Sense, a second wire reads the actual voltage at the battery and signals the alternator to increase its voltage output to compensate for voltage drop, ensuring a constant 14 volts at the battery. Research has shown that an increase of just one half of a volt, when needed, can cut the battery charge time in half. It makes the difference between batteries that are fully charged and other batteries that aren’t.
