Introducing the Chevrolet Silverado 3500 Oil Fill Cap by Wehrli, crafted from Billet Aluminum and finished with a sleek Black Anodized coat. This premium oil fill cap is designed specifically for 2001-2025 Chevrolet Silverado and GMC Sierra models, especially those equipped with the robust 6.6L Duramax engine. Unlike mere covers, this cap serves as a full replacement, offering both aesthetics and functionality in one package.

This well-engineered piece is a direct OEM replacement for several GM model numbers, including 97350955, 97216410, 12573341, and 12677347, ensuring compatibility and ease of installation. The cap features a precisely engineered o-ring seal and a machined cam lock engagement for maximum security and durability. Proudly CNC machined in the USA, it's not just designed for Duramax engines, but also fits the GM LS gasoline engines, ranging from 4.8L V8 to 7.0L V8 configurations. The oil fill cap also complements WCFab's Billet Aluminum Coolant Tank and Brake Reservoir Caps, providing a consistent and polished look under the hood.
