The Serpent SER110421 Shim pack contains 4x9.5x4mm shims intended for precise spacing tasks. They are useful when fine tolerance changes are needed during builds or maintenance.
Employ these shims to correct play, set gear clearances, or level mounting points. Consistent shim placement can improve drivetrain efficiency and cornering predictability.
Because they fit many different component styles, these shims are a handy general-purpose part for racers and weekend builders alike.
