MSD Performance from Start to Finish

MSD DynaForce Starters feature a three horsepower motor to crank over the reduced 4.4:1 gear set to deliver great torque 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, MSD made the billet mount so it can be clocked in different positions to help in tight applications. The DynaForce Starter is powder coated MSD red and will stay looking good, even though it's underneath your car. DynaForce Starters are hand assembled in the USA and never rebuilt or refurbished units.
