Why Upgrade Flex Plate Bolts?

Factory bolts:

• Can stretch under load
• May loosen over time
• Aren’t designed for high-horsepower builds

ARP Fixes That:

• High-strength alloy steel construction for maximum durability
• Improved clamp load to keep flex plate secure
• Precision-machined threads for accurate torque
• Reusable hardware (ditch torque-to-yield bolts)

Translation: your drivetrain stays intact—even when you launch it like you mean it.

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