Two-Zone & Indirect Cooking for Kamado Joe Big Joe Grills

The Kamado Joe Big Joe 19.5" Ceramic Half-Moon Deflectors are the genuine Kamado Joe replacement heat deflectors for the Divide & Conquer Flexible Cooking System in Big Joe Series grills and the Konnected Big Joe.

Replace lost, cracked or broken original deflectors, then use one half-moon for direct and indirect cooking at the same time or combine the pair for full indirect barbeque, smoking, roasting and baking.

Designed for the Big Joe Divide & Conquer System

The 19.5" half-moon shape matches the split layout of the Kamado Joe Divide & Conquer system, allowing each side of the grill to be configured independently.

With one deflector installed, one side remains open to direct charcoal heat while the other side is protected for indirect cooking. Install both deflectors when you want broad indirect coverage for brisket, ribs, pork butt, poultry and other low & slow cooks.

Kamado Joe Big Joe Divide and Conquer System set up for two-zone cooking with one 19.5-inch ceramic half-moon heat deflector. Kamado Joe Big Joe Divide and Conquer System with pair of 19.5-inch ceramic half-moon heat deflectors for full indirect barbeque cooking.

Recommended Barbeque Setup

For longer barbeque cooks, CGS recommends positioning the deflectors low in the Divide & Conquer system while keeping them raised above the charcoal.

Kamado Joe Big Joe Divide and Conquer rack with Accessory Rack positioned low to support ceramic half-moon heat deflectors.

The Kamado Joe Accessory Rack provides a convenient lower position for the deflectors. Raising the ceramic out of the firebowl helps maintain airflow around the charcoal while keeping the heat shield well below the food.

Kamado Joe Big Joe Divide and Conquer barbeque setup with ceramic half-moon deflectors, CGS ceramic spacers and stainless drip pan.

For a complete barbeque setup, add a drip pan above the deflectors and use CGS Ceramic Spacers to create an air gap between the hot ceramic and the pan.

Where Should the Deflectors Sit?

For barbeque cooks, CGS recommends supporting the deflectors on the Kamado Joe Accessory Rack at the lower level of the Divide & Conquer system.

Keeping the deflectors above the firebowl provides room for air to move around the charcoal while maintaining good separation between the fire and food.

The exact position can vary depending on the Divide & Conquer rack version and the rest of the cooking setup.

Using a Drip Pan

For barbeque cooks, we strongly recommend placing a stainless steel drip pan above the ceramic heat deflectors.

Ceramic is porous and can absorb grease and moisture. Reheating trapped moisture can create steam inside the ceramic and place additional stress on the deflector.

A drip pan helps keep grease off the ceramic, reduces buildup inside the grill and makes cleanup easier after long cooks.

For easier cleanup, line the pan with foil in an overlapping + pattern.

Benefits of Ceramic Spacers

CGS Ceramic Spacers create an air gap between the ceramic heat deflectors and drip pan.

  • Under a drip pan: Helps reduce scorching and burnt drippings
  • Thermal separation: Reduces direct radiant heat transfer from the ceramic into the pan
  • Added lift: Helps position the drip pan higher when the rack configuration allows

On two-tier Divide & Conquer systems, the spacers are an easy way to separate the drip pan from the deflectors.

On three-tier systems, you may also be able to use a second Accessory Rack above the deflectors to support the drip pan.

Replacing Lost, Cracked or Broken Deflectors

These are genuine Kamado Joe ceramic deflectors, making them the direct replacement for original Big Joe heat deflectors that have been lost, cracked or broken.

Ceramic heat deflectors operate in one of the hottest areas of the grill and can eventually crack or break from handling, impact or repeated heating and cooling cycles.

A cracked deflector may sometimes remain usable depending on the location and severity of the crack. Replace the plate if it becomes unstable, separates into pieces or can no longer sit securely in the cooking system.

Because fit between the ceramic and Divide & Conquer system is important, genuine Kamado Joe replacements remove the uncertainty of trying to match an aftermarket plate to the original dimensions.

Care & Maintenance
  • Do not use soap, detergents or chemical cleaners on the porous ceramic.
  • Do not clean the deflectors in a dishwasher or submerge them in water.
  • Scrape away loose food debris after the ceramic has cooled.
  • Use a drip pan to help protect the ceramic from grease buildup.
  • Avoid aggressive high-heat cleaning burns.
  • Allow the ceramic to heat and cool gradually whenever possible.
  • Expect the natural ceramic surface to darken with normal use.
Frequently Asked Questions

Are these genuine Kamado Joe deflectors?

Yes. These are genuine Kamado Joe 19.5" ceramic half-moon heat deflectors for the Big Joe Divide & Conquer cooking system.

Are the deflectors sold individually or as a pair?

They are sold as a pair and include two ceramic half-moon deflectors.

Do I need both deflectors for brisket, ribs or pork butt?

Yes. Use both 19.5" half-moons when you want full indirect coverage for traditional low & slow barbeque.

Can I cook with only one deflector?

Yes. One deflector creates an indirect zone on one side of the grill while leaving the other side open to direct charcoal heat.

Why use an Accessory Rack for the deflectors?

The Accessory Rack supports the ceramic lower in the Divide & Conquer system while keeping it raised above the charcoal for better airflow around the fire.

Should the drip pan sit directly on the deflectors?

We prefer an air gap between the ceramic and drip pan. CGS Ceramic Spacers help reduce radiant heat reaching the pan and can minimize burnt drippings during long cooks.

Will the ceramic darken with use?

Yes. Ceramic heat deflectors naturally darken as they are exposed to smoke and cooking residue. This is normal and does not affect cooking performance.

Can I clean the deflectors with a high-heat burn?

We do not recommend aggressive high-heat cleaning burns. Scrape away loose debris and gently burn off remaining residue at moderate temperatures as needed.
