Why Upgrade Flex Plate Bolts?

OEM bolts are fine… until:

• You add power
• You launch hard
• You actually use your car like it wasn’t built for grocery runs

Common Failures with Stock Bolts:

• Bolt stretch under torque load
• Loosening over time
• Flex plate misalignment or failure

ARP Fixes All of It:

• Higher clamp load keeps everything tight
• Stronger material resists fatigue and shear
• Precision threads ensure proper torque retention

Basically, your drivetrain stops being a liability.

Today, ARP product line incorporates thousands of part numbers, and has expanded to incorporate just about each and every fastener found in an engine and driveline. These vary from quality prime performance OEM replacement parts to exotic specialty hardware for formula 1, IndyCar, NASCAR and NHRA drag racing and marine applications.
