Why Upgrade Balancer Bolts?

Factory bolts:

• Can loosen from vibration
• Aren’t ideal for high-RPM builds
• Don’t always hold up to repeated installs

ARP Fixes That:

• High-strength alloy construction for durability
• Improved clamping force to keep balancer secure
• Precision threads for proper torque retention
• Reusable hardware for multiple installs

Translation: your balancer stays exactly where it belongs.
