Key Features:

• 3.73:1 gear reduction for increased cranking speed
• Billet aluminum adjustable mounting block for versatile installation and optimal clearance
• Heavy-duty high-temperature solenoid compatible with 12-16 volt electrical systems
• Plated disc and contacts reduce arcing and increase continuity
• Ball bearing-supported armature for smooth engagement and extended service life
• Compact, downsized housing clears most headers and oil pans

• Durable black powder coat finish for maximum protection
• Compatible with 153/168 tooth flywheels

Built for extreme durability, the MSD DynaForce Starter is designed to reliably start stubborn race engines with high compression ratios. The adjustable mounting block can be clocked to different positions for tighter clearance applications, making installation versatile across Chevrolet small and big block V8 engines with straight mount holes.
