Starter shims may be small, but they play a big role in proper starter installation—especially on older vehicles. Positioned between the starter motor and the engine block, these thin metal pieces ensure correct spacing between the starter gear and the flywheel. Without proper alignment, the starter can grind, clash, or even damage the flywheel, leading to costly repairs. Choosing the right shim thickness ensures smooth engagement, quieter operation, and longer starter life. When replacing a starter, always check the manufacturer’s instructions—some applications require precise measurements to determine if a shim is needed. Helping your customers understand and use starter shims correctly can prevent damage, save time, and improve performance.
