BBC Balancer Bolt Kit

The BBC Balancer Bolt Kit (Part Number 235-2501) is designed for big-block Chevy engine builders and mechanics who require reliable fastening solutions during high-RPM operation. This kit is essential for ensuring the harmonic balancer is securely attached, which is critical for absorbing crankshaft vibrations and protecting the drivetrain from harmful harmonic forces.

Manufactured by ARP, these fasteners are made from premium-grade alloy steel, ensuring consistent tensile strength and reliability. The bolts feature precisely controlled thread geometry and hardness ratings that exceed OEM specifications, significantly reducing the risk of fastener failure under high-RPM loads. This kit is engineered to maintain proper clamping force on the balancer hub, preventing slippage or deflection that could lead to timing errors and catastrophic engine damage.

Ideal for street engines, forced-induction builds, and full-race BBC applications, this bolt kit provides the necessary reliability that stock fasteners cannot offer. Whether you're assembling a powerful 427 stroker or rebuilding a vintage muscle car engine, the ARP Balancer Bolt Kit is a trusted choice for performance enthusiasts.
