Quick answer

The Onlyfire GCG-8552 Cooking System is a smart buy if the sizing fits: it's not a single piece but a complete multilevel cooking system, with two stainless-steel grates, a riser rack and two half-moon ceramic heat deflectors. It turns a Large ceramic egg into a two-height, two-zone convection oven, and it's a lot of accessory for the money. It's for owners of a Large kamado (Big Green Egg Large, Kamado Joe Classic and compatibles). Skip it if your kamado is Mini, Small or XL, or if you already have a stock Divide & Conquer system.

Not a single piece: a complete multi-level cooking system. It includes two stainless steel grates, a riser rack and two half-moon heat deflectors. Turns a Large ceramic egg into a two-tier convection oven.

The holy grail of kamado cooking is managing zones and heights: direct down low, indirect up high, deflectors in between. This Onlyfire kit hands you every piece at once — two stainless grates, the riser rack and the half-moon deflector pair — sized for Large ceramic eggs like a Big Green Egg Large or Kamado Joe Classic. It's the cheapest way to build a full Divide & Conquer setup if your kamado didn't ship with one.

Editor's verdict

The complete kit to build multi-level cooking on a Large ceramic egg. A lot of accessory for the price; just confirm your kamado is Large-sized first.

Editorial rating from spec sheet, measurements and kamado fit · not a hands-on test

Pros

  • Complete system: 2 stainless grates + riser rack + 2 deflectors
  • Enables two-zone, two-tier cooking in a single setup
  • Stainless steel that withstands the kamado thermal cycle
  • Far cheaper than buying each piece separately

Cons

  • Sized for Large kamados only
  • If you already have a stock Divide & Conquer, you duplicate pieces
  • The multi-tier setup eats headroom: less clearance above the grate

Who it's for

For owners of a Large ceramic egg (Big Green Egg Large, Kamado Joe Classic and compatibles) who want two-zone, two-tier cooking without buying piece by piece.

Not for

If your kamado is Mini/Small/XL the dimensions won't fit. And if you already own a stock Divide & Conquer system, this kit duplicates pieces you have.

FAQ

  • What is included in the Onlyfire GCG-8552 system?

    The set includes 2 grates, a height rack and 2 heat deflectors, designed for Large (18") kamados. In short it builds a two-level cooking system with an indirect zone in one go, similar to Divide & Conquer but generic and more affordable.

  • Does it fit a Kamado Joe Classic or a Big Green Egg Large?

    It is meant for Large-mouth kamados around 18", which covers the Kamado Joe Classic, the Big Green Egg Large and similar units. That said, internal dimensions vary by brand, so measure your grate diameter before ordering. It is a universal alternative to the official parts.

  • What material are the grates and deflectors made of?

    The grates are stainless steel and the deflectors refractory ceramic, the usual pairing in these systems. Stainless steel survives washing and will not rust like a basic grate; the ceramic spreads heat and blocks direct flame. Treat the deflectors like any kamado ceramic: gradual heating and no thermal shock.
