Explore the Innovators West range at Platinum Racing Products, including Nissan RB harmonic balancers developed in collaboration with PRP and produced specifically for us, plus accessory pulleys and installation tools.

The Street Extreme (STX) and Race Extreme (RACEX) balancers use wet-friction clutch damping with spring-loaded inertia rings to help control crankshaft torsional vibration.

Choose the STX for the standard 30mm RB crankshaft snout, with the alternator and water pump drive pulley included, or the RACEX for the 35mm snout on PRP-supplied Callies crankshafts, with belt pulleys available separately.

Complete your setup with alternator and power steering pulleys, harmonic balancer installation/removal tools and RB/JZ crankshaft adaptors. For builds retaining power steering and air conditioning, the optional PS pulley works with the PRP AC relocation kit to drive both accessories.
