ATI Performance Products Super Damper Harmonic Balancer Big Block Chevy

The ATI Performance Products Super Damper harmonic balancer (also called a harmonic damper or crankshaft damper) is built for Big Block Chevy engines. It controls torsional crankshaft vibration, which can waste power and wear engine components. It suits street performance, truck, and racing builds.

Key Features:

• Elastomer damping design with a three-ring construction and computer-machined grooves
• Tunable and rebuildable, so it can be serviced instead of replaced
• Works across the RPM range, from street driving to high-RPM racing
• Meets or exceeds SFI 18.1 specifications
• Laser-engraved 360-degree timing marks for accurate tuning
• Black finish
• Made in the USA

By reducing vibration, the Super Damper helps protect the crankshaft and timing gear. It also reduces parasitic losses, so the engine can make better use of the power it produces. ATI Performance Products draws on more than 40 years of transmission and performance component manufacturing and racing experience.
