ARP 102-2501 Harmonic Balancer Bolt for Nissan RB26
This bolt is a key upgrade when considering the reliability of your Nissan RB26DETT engine. Usually paired with the replacement of the harmonic balancer. With the additional clamping force the ARP hardware provides you can ensure that the harmonic balancer isn't going anywhere on your setup.
As the crankshaft flexes, the balancer absorbs incredible amounts of energy. ARP balancer bolt kits will ensure that your balancer is locked into position. They feature a 1/4 in. thick wide-area washer and an extra-tall, 12-point head that accepts a deep socket to eliminate the fear of stripping the head.
