    Rated 5 out of 5 by from LS2 Harmonic Damper Install Tool Purchased this to replace the harmonic damper on my LS2 2005 Corvette. Since the engine was in the car I had to cut off about 1 1/4" of the threaded rod to clear the radiator and electric fan. There was still plenty of threads to engage in the crankshaft for installation. After that I had the new damper installed in a few minutes.
