Description

The harmonic damper is critical to LS1 engine reliability—it absorbs destructive crankshaft vibrations that can lead to premature bearing wear and catastrophic failure. ATI’s Super Damper technology provides superior vibration isolation compared to OEM units, making it essential for high-RPM applications, forced induction builds, and street/strip engines that demand longevity. SFI 18.1 certification ensures this damper meets safety standards for competition use.
