Good To Know

Q: Why choose a forged piston over a cast piston? A: Forged pistons are stronger and more heat resistant, making them ideal for high-performance and racing engines that operate at higher RPM and temperatures.

Q: What is the recommended break-in procedure? A: Follow the manufacturer's break-in schedule, typically involving gentle runs with varying throttle to seat the rings properly before hard use.

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