JE Pistons Wire Lock Chrome Silicon 0.827 in 0.063 in

Wrist pin retainer JE Pistons Wire Lock secures the piston wrist pin with a chrome-silicon clip designed to maintain reliable retention under repeated thermal and mechanical cycling.

This JE Pistons Wire Lock is engineered for precise pin retention using proven materials and dimensions to deliver consistent fit and service life in high-demand engine applications.

• Wire lock retainer — Provides a compact, positive retention method that resists axial movement of the wrist pin during reciprocating operation, reducing risk of pin walk or piston damage.
• Chrome silicon construction — Offers high fatigue strength and corrosion resistance, ensuring the retainer retains spring tension and dimensional stability through heat and load cycles.
• 0.827 in. diameter — Dimensioned to match intended wrist pin bores for a controlled interference and seating position; critical for maintaining axial location and consistent piston behavior.
• 0.063 in. lock thickness — Provides sufficient cross-section to resist deformation while allowing proper insertion and seating in the piston pin boss groove.
• Wrist pin retainer function — Keeps the wrist pin secured within the piston to maintain piston-to-rod alignment and engine durability under dynamic conditions.
• Each — Supplied individually for selective replacement or spares management in engine rebuilds.

Brand: JE Pistons — Manufactured to support JE Pistons’ engineering standards for performance engine components and to integrate with their piston platforms where this style of wire lock is specified.
