Why You Want It
Because flexplate failure ruins days fast. Factory bolts can stretch and lose clamping force over time, especially under boost and hard launches. ARP flexplate bolts provide superior strength and consistent torque, helping prevent flexplate movement, vibration, and crank flange damage. If you’re reinstalling a transmission or finishing an engine build, upgrading these bolts is cheap insurance that keeps your rotating assembly locked in where it belongs.
