| As the crankshaft attempts to flex and twist apart, the damper absorbs incredible amounts of kinetic energy - these chrome moly bolts exert 190,000psi clamping force to lock the damper in position. Special features include 1/4” thick, wide area washer and an extra tall 12 point head that accepts a deep socket and eliminates the worry of stripping the head. | |||
