ATI Performance Products, Inc. is proud to introduce its all new Super Damper (Part # 918573) for the 2020 Toyota Supra and 2019 BMW Z4 engine for street and high performance racing applications. The new aluminum-shell, steel-hub damper is a direct fit replacement for the stock OEM unit and is better capable of handling a wider variety of driving habits that Supra and Z4 owners will put their new cars through. OEM dampers are optimally tuned to a narrow band of perceived normal driving conditions and do not perform well outside of those limits. The ATI Super Damper can handle any engine speeds and driving conditions that get thrown at it to better protect your engine. ATI Super Dampers provide balanced dampening of torsional crankshaft vibrations through all RPM ranges and exceed SFI 18.1 Safety Certification for competition use. It’s no surprise that they are the crankshaft damper preferred around the globe by the best drag racing, endurance, diesel and NASCAR engine builders.ATI Performance Products, Inc. is located in Baltimore, MD, and specializes in producing and maintaining high performance products for street and strip applications.
