Description
It took us nearly three years to convince ATI to manufacture a custom SFI-approved Super Damper® for our engines, but now it’s finally happening! These are the best of the best, and will allow your LF4 engine to safely handle more power. Fits all LF3 and LF4 applications from 2014 through 2023.
Find more details from ATI HERE.
You will need a special TorxPlus TP40 socket to assemble the Super Damper. Also note that GM and ATI recommend replacing your crankshaft bolt any time it is removed.
Made in U.S.A.!
