MANLEY 42243-4 Piston Wrist Pin 21mm x 2.250

Description MANLEY 42243-4 Piston Wrist Pin 21mm x 2.250

Manley Performance wrist pins are precision-engineered to handle extreme stress and high-RPM conditions, making them an essential upgrade for performance engine builds. Manufactured from premium materials such as 4130 and 300M steel alloys, these wrist pins offer tensile strength, durability, and resistance to wear under intense combustion pressures.

With standard and tool steel options, Manley wrist pins are designed for high-performance piston applications, ensuring optimal fitment / vehicle compatibility and reliability. Precision-ground surfaces and a case-hardened finish reduce friction and improve longevity, enhancing overall engine efficiency.

Many models also include DLC (Diamond-Like Carbon) coatings for reduced wear and improved oil retention, making them suitable for extreme racing and forced-induction applications.
