The LS3 7.48 Harmonic Damper 6-Groove SFI by ATI Performance is designed for high-performance LS engine builds, ensuring precise control over crankshaft harmonics. This damper is essential for applications ranging from naturally aspirated strokers to boosted LS3 setups, particularly in competitive environments where engine reliability is paramount.
Constructed to meet SFI 18.1 certification standards, the damper effectively isolates harmful harmonic vibrations that can lead to engine wear. Its 7.48-inch diameter and 6-groove design are tailored for LS3 crankshafts, optimizing mass distribution and damping characteristics across various RPM ranges. The elastomer construction absorbs torsional energy, minimizing peak stress on critical engine components.
Ideal for LS3 engine swaps and crate engine installations, this damper offers a direct fit to LS3 cranks, eliminating the need for universal dampers. Installation is straightforward, requiring only the removal of the factory damper and proper torque specifications for secure fitting. This product is perfect for those pushing beyond OEM power levels, ensuring enhanced performance and longevity.
