93 Series Piston Pin .990 x 2.930 x 200w

The 93 Series Piston Pin .990 x 2.930 x 200w by JE PISTONS is a precision-engineered wrist pin designed for high-performance engine builds and race applications. This component serves as the critical pivot point connecting the piston to the connecting rod, making it essential for builders pursuing power gains through forced induction, high-RPM naturally aspirated engines, or competition platforms. Understanding piston pin specifications is fundamental to ensuring reliable power transfer and preventing catastrophic engine failure in modified applications.

The .990-inch diameter and 2.930-inch length specifications define this pin's compatibility with JE's 93 Series piston family, engineered for demanding boost pressures and extended RPM ranges. The 200-weight designation indicates this pin's intended load capacity and material specification, crafted from premium alloy steel to withstand the cyclic stresses of high-horsepower engines. JE PISTONS maintains strict tolerances and heat-treatment protocols to ensure consistent durability, minimal deflection under load, and precise fitment with both the piston boss and connecting rod small end, critical factors that directly impact engine reliability and longevity in turbocharged or supercharged platforms.

Engine builders targeting 700+ horsepower applications, drag racing competitors, and street-performance enthusiasts standardize on JE 93 Series pistons and their corresponding pins when reliability cannot be compromised. Installation requires proper honing of the piston pin boss and rod eye to maintain clearance specifications—typically 0.0005" to 0.0015"—and verification that your connecting rod is sized for .990" pin diameter. This piston pin is sold individually; confirm your engine displacement and piston count before ordering the complete set required for your build.
