Piston Pin .927 x 2.288 .188 Wall - 128-Grams

The Piston Pin .927 x 2.288 .188 Wall by MAHLE PISTONS is a precision-engineered connecting pin designed for high-performance engine builds and race applications. As a critical component linking the piston to the connecting rod, this piston pin transfers combustion forces while allowing the necessary articulation for smooth engine operation.

Manufactured by MAHLE—a trusted name in OEM and performance pistons—this pin features a .927-inch outer diameter with a 2.288-inch length and .188-inch wall thickness, optimized to handle the stresses of both stock and modified powerplants. The weight specification of approximately 131 grams is critical for engine balance calculations; even minor weight variations affect rotating assembly dynamics and can create vibration or bearing wear.

This piston pin serves small-block and mid-displacement engine platforms commonly found in street rods, race engines, and restoration projects. Installation requires proper piston-to-rod fitment and typically demands a press fit or snap-ring retention depending on your specific piston design—always verify compatibility with your piston manufacturer's specifications.
