ATI Performance Products ATI917515 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI917515 Super Damper is a high-performance elastomer harmonic balancer designed to reduce crankshaft torsional vibration and protect your engine's rotating assembly. ATI Super Dampers are engineered for racing and high-performance street applications where stock or OEM-style dampers fall short under extreme RPM and power levels.

ATI Super Dampers use a precision-machined, multi-piece design with a tuned elastomer ring that absorbs and dissipates harmful crankshaft harmonics across a broad RPM range. Unlike conventional bonded dampers that can delaminate or fail under heat and stress, the ATI design maintains consistent damping performance over the life of the part.

Key Features:

• Precision-machined billet steel or aluminum construction for superior strength and durability
• Tuned elastomer damping element for broad-range harmonic control
• SFI 18.1 certified for sanctioned racing use (verify SFI status for specific application)
• Laser-engraved timing marks for accurate ignition timing
• Rebuildable and re-tunable design — elastomer can be replaced without replacing the entire damper
• Compatible with ATI Pro Pulley accessory drive systems
• Manufactured in the USA by ATI Performance Products

The ATI917515 Super Damper is a direct replacement upgrade over the factory harmonic balancer, providing enhanced protection for high-horsepower, high-RPM engines used in drag racing, road racing, and performance street driving. Always verify application fitment before installation.
