Why Stronger Connecting Rods Matter

Connecting rods are responsible for transferring force between the piston and crankshaft. Under higher boost levels or aggressive tuning, these forces increase dramatically.

Stronger rods help:

• Prevent rod failure under high horsepower

• Maintain engine stability at high RPM

• Support turbocharged performance builds

• Improve long-term engine reliability

For serious Miata builds, upgrading the bottom end ensures the engine can handle increased power safely.
