We recommend a cross-pattern torque sequence on the 6-bolt mounting flange to ensure even pressure. Always verify your starter drive is compatible with the 197-tooth ring gear to ensure reliable ignition and prevent premature gear wear. CRITICAL: Verify Specifications Please confirm your engine size and original casting number match these specifications. The 6-inch bore size and 197-tooth ring gear are essential for proper fitment and vehicle safety. Shipping Note: All flywheel orders are drop-shipped directly to ensure the fastest delivery.
