ARP's Harmonic Balancer Bolt Kit, for all 2011, 2012, 2013 and 2014 5.0L Mustangs, is manufactured in the USA and contains the bolt and washer, as well as ultra-torque fastener assembly lubricant necessary for correct and secure installation.

ARP has developed these ultra-strong Harmonic Balancer Bolts that let you exert maximum clamping force to ensure that the balancer is securely locked in position. Constructed from 8740 Chromoly with a black oxide finish, these bolts are rated at 200,000 psi tensile strength! An extended length and a 12-point head accept a deep socket which provides this bolt with increased resistance to stripping.

Reducing torsional vibration is pivotal to preventing overwhelming resonance and eventually crankshaft failure. As the crankshaft flexes and twists, the harmonic balancer absorbs incredible amounts of kinetic energy. This high quality and sturdy ARP Harmonic Balancer Bolt Kit helps to maintain the integrity and firmness of the harmonic balancer, or crankshaft damper, in all 2011, 2012, 2013 and 2014 5.0L Mustangs.
