Description
Upgrade your fuel & DEF caps with this DmaxStore Billet Fuel & DEF Cap Bundle, designed specifically for 2020–2026 Chevrolet Silverado & GMC Sierra 2500HD/3500HD equipped with the 6.6L L5P Duramax Diesel.
Both caps are precision-machined from 6061-T6 billet aluminum for superior durability and corrosion resistance. The fuel cap is anodized green and the DEF cap anodized blue, providing a clean appearance and a clear reminder of fluid location.
No more setting your cap on the bed rail and forgetting it at the pump. The billet fuel cap threads directly into the factory filler neck and is engineered for proper fitment across all 6.6L Duramax models.
