Precision Fasteners for GM LS-Series Engines

The GM LS-series engine is known for its incredible power potential, but that power demands high-quality fasteners. The Auto Racing Products (ARP) LS-Series Harmonic Balancer Bolt is designed to keep your balancer secure under the most demanding conditions. Featuring a 16mm x 2.00 thread and a generous 4.325-inch length, this bolt is the ideal choice for any LS build (excluding LS7).

Engineered for Performance

• 12-Point Head: 1-1/16 inch head size for easy, high-torque installation.
• High-Strength Chromoly: Heat-treated 8740 steel provides superior tensile strength.
• Black Oxide Finish: Resists corrosion for a long-lasting, clean look.
• Reliability: Prevents balancer walk and potential crankshaft damage.

LS engines generate significant vibration, and a loose harmonic balancer can lead to severe engine failure. This ARP bolt is designed to provide the exact clamping force required to keep the balancer firmly attached to the crankshaft snout. Whether you are building a stock replacement or a high-boost forced induction setup, this fastener provides the security you need. Don't settle for inferior hardware when building your LS engine. Ensure your build is protected with the highest quality components from GGCRACING.
