We recommend measuring your existing brushes or checking your vehicle's alternator specifications before purchase to confirm fitment.\u003c\/p\u003e\n\u003ch4\u003eQ: Why do alternator brushes need to be replaced?\u003c\/h4\u003e\n\u003cp\u003eA: Alternator carbon brushes transfer electrical current to the rotating slip rings inside the alternator. Over time, normal wear reduces their length, leading to reduced charging output or a complete charging failure. Replacing worn brushes with fresh carbon and copper alloy units restores proper electrical contact and charging performance.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I know which size brush I need?\u003c\/h4\u003e\n\u003cp\u003eA: Remove the old brushes from your alternator or voltage regulator and measure the width, height, and length (in mm). Compare your measurements to the three sizes included in this pack — 4.5 × 6.5 × 20 mm, 5 × 7 × 20 mm, and 5 × 8 × 20 mm — and select the closest match. Having all three sizes in one purchase saves time and ensures you have a spare on hand.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
