Mad4Metal Pontiac SD-389 Super Duty Billet Aluminum Badge CNC USA

CNC Machined in the USA | 6061 Billet Aluminum | Complete Hardware Kit Included In 1961, Pontiac handed a small number of dealers something that wasn't supposed to exist: a factory-built drag racing engine. The Super Duty 389 was assembled with aluminum intake manifolds, long-branch exhaust headers, solid lifter camshafts, and reinforced bottom ends — all from the factory, all designed for one purpose. The cars that carried it, mostly stripped Catalinas, were as close to a purpose-built race car as you could buy with a window sticker. The SD-389 is rare, historically significant, and almost entirely forgotten outside of serious Pontiac circles. This badge is for the people who know exactly what it is. This is the Mad4Metal Pontiac SD-389 badge — machined from a solid billet of 6061-T6 aircraft-grade aluminum. The SD-389 designation is CNC cut directly into the face and hand-polished to a mirror finish. No paint fill, no printing, no adhesive backing. Just aluminum and a cutting tool. Not stamped. Not cast. Not a sticker. Machined. Hardware holes bored at 2-3/8" center-to-center on 1/4"-28 fine thread. Mount it on the valve cover and it sits there like a factory callout — because that's exactly what it is. About the Finish These badges are polished to a mirror finish, but if you look closely you'll see the machining marks from the CNC cutting process — fine, consistent toolpath lines across the face. Those marks are intentional. They're what separates a real machined billet part from something that was painted, cast in a mold, or made to look like metal. A perfectly mark-free, glassy smooth surface would look like painted plastic. The toolpath lines catch light at different angles depending on where you're standing, and that shifting reflection is the signature of a part that was actually cut on a machine. If you want to bring up the high spots even more, a quick pass with aluminum polish will do it — while keeping the machining character completely intact. Where Can You Run It?

Plastic fades, chalks, and eventually falls apart. Stick-on emblems peel, every time, guaranteed. 6061-T6 aluminum doesn't do any of those things. It's the same alloy used throughout the aerospace industry: light, strong, corrosion-resistant, and indifferent to the temperature swings a running engine produces. When the finish dulls, you polish it back. No repainting, no replacing, no starting over. A Super Duty deserves hardware built to the same standard.
