This Wiseco SW 9310 series wrist pin is engineered to manage the extreme reciprocating forces within the engine bore, capable of handling high-load performance applications. Precision-manufactured from high-strength 9310 alloy steel, these pins provide the structural integrity and surface hardness required to prevent galling and deformation under stress.

Every Wiseco wrist pin is ground to exacting tolerances to ensure a proper fit between the piston and the connecting rod small end, maintaining oil film consistency and reducing friction. This specific pin is designed for builders requiring a 21mm diameter pin with a heavy-wall cross-section for maximum rigidity.
