High-horsepower Nissan RB engines place enormous loads on the crankshaft and harmonic balancer assembly. The JHH Racing Nissan RB Crank Bolt was developed to provide superior damper retention and clamping force in demanding performance applications.

Precision machined from billet EN26 high-tensile steel, this crank bolt features an integrated large-diameter flange in a one-piece design. The increased flange surface area delivers up to 30% greater surface friction compared to conventional crank bolt designs, helping to minimise the risk of damper movement under extreme engine loads.

Designed specifically for high-output Nissan RB engine builds, this heavy-duty crank bolt provides the strength and reliability required for motorsport, drag racing, and high-boost street applications.
