239818 Kb Piston Spiral Lock Circlip Each

This KB Keith Black Performance Motorcycle Pistons spiral lock circlip is engineered to provide maximum security for piston pins in high-performance Harley-Davidson engines. Unlike standard snap rings, the spiral design offers 360-degree contact within the groove, preventing the pin from walking and causing cylinder wall damage. These locks are specifically suited for use with forged 4032 alloy pistons in high-compression or nitrous-assisted race and street applications. Keith Black components are trusted for their precision and ability to withstand the thermal expansion and mechanical stresses of high-RPM operation. Using these spiral locks ensures a reliable connection between the piston and connecting rod during the most demanding riding conditions.
