The Ferrari flange-shim (SKU fe-173360) is a precision spacer designed to help maintain accurate flange alignment across compatible assemblies. This small but critical component supports proper sealing, load distribution, and long-term durability in Ferrari service and routine maintenance. When installed correctly, it helps preserve performance, reduce stress on mating parts, and maintain consistent operation under typical driving conditions. Designed to complement Ferrari engineering standards, this shim provides reliable, repeatable alignment when servicing key joints. What is the flange-shim? A flange-shim is a thin, precision spacer placed between two flange surfaces to adjust spacing and alignment. It helps align bolt holes, maintain parallel faces, and ensure proper seal compression. Used in a range of Ferrari assemblies, the shim allows minor adjustments without replacing larger components, contributing to reliable mating surfaces, reduced leak potential, and smoother load transfer. The shim accommodates small variances that can occur during maintenance, temperature changes, or wear, helping restore proper geometry for secure connections. Why is the flange-shim Important?
