About this item

  • 3/4" Depth and can be used on 157 and 164 Tooth Flywheels
  • Also Available in Black
  • Ball bearing supported armature and pinion gear
  • Downsized design helps clearance issues with oil pans and exhaust
  • Gear reduction of 4.4:1 improves torque for great cranking


Our advanced power system line has grown to include starters. Our new APS starter is designed to crank over the highest compression engines on a hot day in death valley. Not that too many race cars are sitting in death valley, but it's good to know that you have the oomph to make it happen. The APS starter features all new components beginning with a three horsepower motor. This power is used to crank over the reduced 4.4:1 gear set to deliver great torque to the engine's ring gear to get the engine turning. The armature is balanced during assembly and is guided by two ball bearings for smooth engagement and thousands of starts. The downsized housing clears most headers and oil pans, but just in case, we made the billet mount so it can be clocked in different positions to help in tight applications. The assembly is powder coated MSD red and will stay looking good, even though it's underneath your car.

Perfect for a 347 stroker mustang.no other starter would work after motor was warmed up Timing was set perfect and the ford high torque would barely turn the motor over.

Stock Starters wouldn't have enough cranking power to turn over my 347 Stroker. This bad boy hasn't failed on 3 different engines and after 2 years of being thrashed upon. MSD did something right with this!

Its definitely worth the money. I used this to replace a stock starter that went out on my mustang and this thing had no problem at all cranking over my 331 stroker engine. Never a sputter or slip hot or cold.
