Super Damper Harmonic Balancer

The ATI Performance 918483 Super Damper is engineered as a stock replacement harmonic balancer for 2015-2017 Dodge Hellcat Charger and Challenger vehicles equipped with the 6.2L Supercharged HEMI engine. This damper boasts an OEM diameter and is constructed with a 2024 billet aluminum shell and a steel hub, measuring 8.190 inches in outside diameter. It features 10 and 6 grooves for belt systems and a single keyway. Unlike OEM dampers that are tuned for a narrow range of driving conditions, the ATI Super Damper is built to handle a wider variety of engine speeds and driving conditions, offering superior protection for your engine. This particular model exceeds SFI 18.1 Safety Certification, making it suitable for competition use. The product page notes that a 10% overdriven version (Part # 918485) is also available, which can increase boost by 3 psi and has yielded 60 more HP at the rear tires with custom tuning.
