Wire Lock - 0.827

The Wire Lock - 0.827 in wrist pin diameter is a precision-engineered retaining component designed for high-performance engine building and piston assembly applications. This steel wire lock secures the wrist pin (connecting rod pin) to the piston, preventing axial movement and ensuring reliable power transfer under extreme combustion pressures. Built by JE Pistons, a trusted leader in performance engine components, this lock is essential for custom engine builds, racing applications, and any rebuild requiring OEM-specification or upgraded piston assemblies.

Manufactured from hardened steel, this wire lock features a 0.063 inch thickness that provides optimal spring tension and durability across repeated compression and power strokes. The 0.827 inch diameter specification ensures precise fitment into the wrist pin groove without excess play or risk of dislodgement during operation. The wire design distributes clamping force uniformly around the pin, reducing stress concentration and extending component lifespan in both naturally aspirated and forced-induction engines. Each lock is individually packaged and ready for immediate installation into compatible piston assemblies.

Engine builders, machine shops, and performance enthusiasts benefit most from this critical fastening component when assembling pistons with 0.827 inch wrist pin bores. Compatibility spans a wide range of domestic and import powerplants where JE Pistons specifications apply, including small-block and big-block variants across multiple manufacturers. Proper installation requires careful alignment during piston assembly to ensure the wire lock seats fully in its groove; improper seating can lead to pin migration and catastrophic engine failure. This is a single lock unit—verify the exact quantity needed for your complete engine build before ordering.
