Wrist Pin Light Weight .927 2.288 .129 92 grams

The MAHLE PISTONS Wrist Pin Light Weight is a precision-engineered component designed for high-performance engine builds where weight reduction and durability are critical. Measuring 0.927 inches in diameter and 2.288 inches in length with a 0.129-inch wall thickness, this wrist pin delivers the strength required for demanding engine applications while minimizing reciprocating mass. Constructed from steel and featuring a C-clip retaining system, this part is engineered to MAHLE's specifications for dependable performance in racing, marine, and high-output automotive environments.

The lightweight design reduces inertial forces on the piston assembly, allowing engines to accelerate more responsively and operate at higher RPM ranges with improved efficiency. At just 92 grams, this wrist pin contributes meaningfully to overall mass reduction in performance rebuilds. The precise dimensional specifications—0.927" bore diameter and 2.288" overall length—ensure proper fit within OEM and performance piston assemblies while the C-clip retention system provides secure, repeatable assembly without requiring hoop stress or press-fit methods that can compromise structural integrity.

This component is essential for engine builders and machine shops specializing in high-performance rebuilds, including racing engines, turbocharged applications, and marine powerplants where every gram of rotating mass matters. Builders working with high-revving gasoline engines or forced-induction setups benefit from the reduced reciprocating weight, which decreases stress on connecting rods and crankshafts while improving throttle response. MAHLE's reputation for piston system precision makes this wrist pin a reliable choice for applications demanding OEM-equivalent or superior performance.
