Understanding the criticality of harmonic resonance in BMW inline-6 engines, ATI Performance Products has collaborated with VAC Motorsports to craft revolutionary dampers. Designed for BMW 2.5L, 2.8L, 3.0L, and 3.2L straight-6 engines in E36 and E46 M3, E9X, E6X, Z3s, and Z4s, these dampers tackle harmonic vibrations, unlocking heightened horsepower, torque, and longevity. Forget about broken oil pumps and timing chains!

Pairing seamlessly with VAC accessory pulleys, these 7" diameter dampers boast OEM-style timing alignment tabs, ensuring a direct fit over OEM balancers. Notably, all ATI Super Dampers exceed SFI 18.1 Safety Certification for competitive use, making them a must-have for BMW enthusiasts. Benefits extend to eliminating vibration issues with lightweight clutch and flywheel assemblies, reducing wear on bearings, engine accessories, and oil pumps, and harmonizing with underdrive pulleys.

Plus, each package includes the lightweight VAC Billet Crankshaft Pulley, proudly made in the USA for uncompromised quality assurance.
