Specs At A Glance

Good To Know

Q: Can I reuse my old flexplate bolts instead of these? A: Flexplate bolts are torque-to-yield in many LS applications and should be replaced rather than reused when servicing the drivetrain.

Q: Do these bolts work with both automatic and manual setups? A: They fasten the flexplate or flywheel to the crankshaft, so confirm your specific transmission and engine combination before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
