Drivetrain Flexplate Bolts for Automatic Builds
On a car or truck with an automatic transmission, a small set of bolts holds the flexplate to the back of the crankshaft. All the engine torque headed for the transmission passes through that joint. The fasteners have to keep their clamping force through heat cycles and hard launches. Many builders fit fresh bolts whenever the flexplate comes off. They also upgrade them when a build makes more power or sees more abuse than stock.
In Drivetrain › Flexplate Bolts we have 3 products in stock, all from ARP. Examples include the ARP 93+ Mitsubishi 4G63 Flexplate Bolt Kit and the ARP GM LS w/ adapter Plate Flexplate Bolt Kit. The LS kit is intended for LS setups that use an adapter plate.
Match the kit to your engine family and model years, not just the make.
Check whether your setup uses an adapter plate or spacer, since that affects which bolts you need.
Follow the fastener maker's torque values and lubricant instructions.
Replace the bolts rather than reuse them if the maker advises against reuse.
To narrow the list, pick your vehicle to see what fits.
