ATI Performance Products ATI949130 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI949130 Super Damper is a high-performance crankshaft harmonic balancer engineered to absorb and neutralize destructive torsional vibrations generated by the crankshaft during engine operation. By effectively damping these vibrations, the Super Damper helps protect critical engine components — including the crankshaft, bearings, and timing components — from premature wear and fatigue failure.

ATI Super Dampers are manufactured in the USA to strict tolerances using premium billet steel or aluminum construction (depending on application), and are designed as a direct, bolt-on replacement or performance upgrade over the factory OEM damper. They are SFI 18.1 certified, making them legal for use in many sanctioned racing classes.

Key Features:

• SFI 18.1 Certified — meets safety and performance standards for sanctioned racing
• Torsional Vibration Damping — protects crankshaft, bearings, and valve train from harmonic stress
• High-Strength Billet Construction — precision-machined for optimal balance and durability
• Performance Upgrade — improves over stock OEM damper design for high-RPM and high-horsepower applications
• Made in the USA — manufactured by ATI Performance Products, a trusted name in racing and performance
• Laser-Etched Timing Marks — for precise ignition timing adjustments

The ATI Super Damper line is a proven choice among professional and amateur racers as well as performance enthusiasts seeking maximum engine protection and reliability. Always verify fitment using ATI's official application guide prior to installation.
