Earl's Performance DBT-004ERL Harmonic Balancer Bolt GM LS Series 12-Point

The Earl's Performance DBT-004ERL harmonic balancer bolt is engineered specifically for GM LS series engines, delivering the strength and reliability needed for critical crankshaft installation. Constructed from premium chrome moly steel with an impressive 180,000 PSI tensile rating, this bolt provides exceptional clamping force to securely retain the harmonic balancer during high-RPM operation.

Key Features:

• Chrome moly steel construction with 180,000 PSI tensile strength rating
• Extra-tall 12-point head design prevents socket slippage and stripping during installation
• Includes extra-thick, large diameter washer for optimal load distribution
• Black oxide coating provides corrosion resistance and professional appearance
• Direct replacement for GM LS series engines (LS1, LS2, LS3, LS6, LS7, LSX, and more)

The 12-point head configuration allows for easier installation in tight spaces with incremental positioning, while the extra height prevents socket walk-off when applying high torque values. The included heavy-duty washer ensures proper load distribution across the balancer hub face, preventing damage during installation and operation. Both the bolt and washer feature a durable black oxide finish that resists corrosion while maintaining a clean, professional look under the hood.
