ARP RB25 RB30 Balancer Bolt

Part number: ARP-NIS-RB25-RB30-HAR-BAL-BOLT

The ARP RB25 RB30 Balancer Bolt replaces the factory hardware on Nissan RB25 and RB30 engines – M16 x 1.5.

This bolt is made from ARP2000 hardware, which provides a more secure torque with far more durability than factory hardware.

Note: The ARP RB25 RB30 Harmonic Balancer Bolt must be used with an OEM washer. Compatible with aftermarket and factory balancers.

ARP2000®: ARP2000 is an alloy steel that can be safely heat treated to a higher level, producing a greater strength material than 8740. While 8740 and ARP2000 share similar characteristics – ARP2000 is capable of achieving a clamp load at 220,000 psi. ARP2000 is used widely in short track and drag racing as an up-grade from 8740 chrome moly in both steel and aluminum rods. Stress corrosion and hydrogen embrittlement are typically not a problem, providing care is taken during installation.

More Information:

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 include 1/4˝ thick, wide area washer and an extra tall 12-point head that accepts a deep socket and eliminates the worry of striping the head.
