Give Your Truck The Cap It Deserves

Let’s face it, the little plastic fuel plug that comes from the factory just doesn’t cut it, especially on a workhorse like your Powerstroke. If you’re tired of flimsy, easy-to-lose caps that barely keep out dust or moisture, the Sinister Diesel Billet Fuel Cap is the upgrade your truck has been waiting for. This thing not only looks sharp with its Sinister Green anodized finish, but it’s also built tough enough to handle the real world. Whether you're out on a job site, hitting the trail, or towing heavy, this cap helps keep contaminants out and performance locked in. It seals tight with a high-quality Viton O-ring and even features a built-in magnet so you can stick it to your fuel door or bed rail while you’re filling up. The laser-etched Sinister Diesel logo gives it a finished, custom look that feels like it actually belongs on your rig. It’s a small upgrade with big-time appeal, both in looks and protection.

Precision Machined To Lock Out The Elements

Behind the bold look of this fuel cap is some serious attention to detail. Each unit is CNC machined from premium T6-6061 billet aluminum for strength that won’t wear down over time like plastic alternatives. The precision threading pairs with the integrated Viton O-ring to provide a tight, water-resistant seal that helps guard your fuel system from dirt, debris, and unwanted moisture. The anodized finish not only looks great but also adds a layer of corrosion resistance for long-term durability. With an internal magnet in the base, you’ve got a practical place to stick it while fueling, no more setting it on your toolbox or forgetting where it rolled off to. Designed specifically for 2008–2020 Ford F250 and F350 Powerstroke trucks, this cap fits like OEM but performs at a much higher level. Whether you're maintaining your daily driver or building a reliable tow rig, this cap is made to keep your fueling system secure and clean.
