Review WSM Platinum Series Top End Kit 0.25mm Oversized To 74.15mm Bore

The WSM 010-870-11 Platinum Top End Kit is a premium upgrade for Weber Smokey Mountain Cookers looking to enhance their grilling experience. This top end kit is designed for 22.5-inch WSM models and comes with oversized parts for improved performance and durability.

The heart of this kit is the 0.25mm thick, porcelain-enameled, 74.15mm diameter cooking grate. The oversized size provides more cooking surface area, allowing you to cook more food at once. The thicker material distributes heat more evenly and retains it longer, resulting in better temperature control and consistent cooking results. The porcelain enamel finish not only looks great but also makes cleanup a breeze.

The center-to-center diameter of the new cooking grate is 23.2 inches, which is 0.5 inches larger than the standard grate. This increase in size provides more flexibility when arranging food on the grate and enables you to cook larger items like whole chickens or roasts without crowding.

The new 0.25mm-thick, porcelain-enameled, 18.5-inch-diameter Platinum Top and Bottom Air Intakes also come with this kit. These oversized intakes provide more airflow to the cooker, improving temperature control and fuel efficiency. The thicker material ensures that they withstand the rigors of frequent use.

Additionally, the WSM 010-870-11 Platinum Top End Kit includes a 0.25mm thick, porcelain-enameled, 18.5-inch-diameter Platinum Drip Pan. This oversized drip pan catches grease and drippings from the food, preventing flare-ups and making cleanup easier. The thicker material ensures that it retains its shape and doesn't warp or bend over time.

Finally, the kit includes a 0.25mm thick, Platinum Ash Catcher. This oversized ash catcher provides more room for ash collection and makes it easier to remove and dispose of the ashes. The thicker material ensures that it withstands the heat and doesn't crack or break.

In summary, the WSM 010-870-11 Platinum Top End Kit is a must-have upgrade for Weber Smokey Mountain Cooker owners. With oversized, 0.25mm thick cooking grate, air intakes, drip pan, and ash catcher, this kit improves temperature control, fuel efficiency, and overall cooking performance. The porcelain-enameled finish not only looks great but also makes cleanup a breeze. This is an investment in your grilling experience that you won't regret.
