Olds Balancer Bolt Kit

The ARP Olds Balancer Bolt Kit (SKU ARP180-2501) is a precision harmonic balancer fastener engineered for high-performance Oldsmobile V8 engine applications. This chromoly bolt serves a critical function in maintaining crankshaft stability and vibration dampening at elevated RPMs, making it essential for both street and competition builds where factory hardware may prove inadequate under sustained load. Technicians and engine builders rely on quality balancer bolts to secure the harmonic balancer without risk of slippage or catastrophic failure.

Manufactured from chromoly steel and finished in black oxide, the ARP Olds Balancer Bolt Kit features a 3/4-16 thread pitch with a 1.300-inch length and 13/16-inch 12-point head design for secure engagement and wrench compatibility. Chromoly construction delivers superior tensile strength compared to standard steel, resisting stretch and yielding under the extreme stresses imposed by harmonic balancer rotation and lateral forces. The 12-point head geometry provides superior contact area and reduced fastener wear during installation and removal cycles, critical for performance applications where multiple engine rebuilds are anticipated.

This balancer bolt kit is purpose-built for Oldsmobile V8 engine blocks and is ideal for engine builders, performance shops, and enthusiasts undertaking crankshaft or harmonic balancer service. Installation requires standard mechanical tools and basic engine work knowledge; proper torque sequencing and thread-locking compound application ensure reliability. The compact 0.63-pound weight reflects a single-bolt specification, though customers should verify fastener quantity requirements for their specific engine platform before ordering.
