ARP - Nissan RB25/RB30 Harmonic Balancer Bolt

Nissan RB25 & RB30 engines.

Arp are the leading brand in fastener technology. All fasteners are made with the highest quality materials with quality assurance testing.

As the crankshaft flexes and twists, the harmonic damper absorbs incredible amounts of kinetic energy. To ensure that the damper is locked in position, ARP has developed these ultra-strong 190,000 psi bolts that let you exert maximum clamping force. Special features include1/4˝ thick, wide area washer and an extra tall 12-point head that accepts a deep socket and eliminates the worry of striping the head.
