Prodsucts Description
4032 forged pistons are a high silicon-based material. This means that they expand much less than 2618 pistons. The tendency to expand less means that the piston can have a tighter piston to bore clearance. The tighter clearances create a quitter overall operation of the motor. 4032 is a very stable allow that resists distortions such as ring integrity. The alloy’s strength and stability also lend its self to a longer life cycle capability. However, due to its less ductile nature, we do not recommend using this type of piston if you’re planning to build your HEMI stroker motor for a boosted application. If you’re looking to build a naturally aspirated HEMI stroker engine and don’t plan on abusing the motor every weekend you should consider a 4032 piston for you build.
