2004-2006 Pontiac GTO Balancer Bolts

There's a good reason that virtually every top professional engine builder relies on ARP® fasteners for their all-out competition powerplants. Simply stated, there’s not a better stud setup on the market today.  ARP Fastners offer high performance reliability you can trust.

On modern GM LSX series engines, a new harmonic balancer bolt is required anytime the harmonic balancer is removed or replaced.  The factory bolts are a "torque-to-yield" type, which means they cannot be reused after they have been removed.
