If your Makita BO4556 sander’s backing pad is worn out, cracked, or just not holding discs well anymore, here’s the exact replacement you need. This is the genuine Makita OEM part (number 158324-9), so it’s made to the same specs as the original—no cheap aftermarket fit issues. It’s a 4-1/2 inch by 4 inch backing pad designed specifically for the BO4556 model, and it installs in minutes. Just make sure your sander is unplugged, remove the old pad, screw this one on, and you’re back to sanding smoothly. Using the right pad means your sanding discs sit flat, wear evenly, and you get a consistent finish every time. Whether you’re refinishing furniture, smoothing drywall, or prepping surfaces for paint, a fresh backing pad makes a huge difference in performance and safety. Keep your sander running like new without buying a whole new tool. Always go with OEM for critical wear parts like this—it’s worth the few extra bucks for reliability.
