Hongso 17 inch Cast Iron Grill Grates Replacement for Pit Boss Memphis Ultimate 4-in-1 — 2-Pack Heavy-Duty SGS-Tested

Heavy-duty cast iron replacement grates sized for the Pit Boss Memphis Ultimate 4-in-1 gas and charcoal combo grill with smoker — two 17 1/16” x 11 1/16” grids that lock in heat for superior searing.

If your original grates are warped, rusted, or missing, these Hongso cast iron grates are engineered to restore even heat, better sear marks, and long-lasting performance. Each set includes two individual grids that can be used separately or together to cover the full cooking area of the Memphis Ultimate 4-in-1. Built from thick cast iron and SGS-tested for safety, they offer the heat retention and durability that home grillers expect.

How will these grates change my grilling results?

Cast iron stores and releases heat far more consistently than thinner metals, so food cooks with steadier contact temperature and clearer sear lines. That translates to better crust formation on steaks, consistent grill marks on vegetables, and reduced hot-spot cooking. Because the grates hold heat, smoke and caramelization develop more efficiently.

• Thick cast iron construction for even heat retention and steady cooking.
• Produces pronounced sear marks and improved caramelization.
• Reduces cold spots and shortens recovery time after lifting the lid.

Will these fit my Pit Boss Memphis Ultimate 4-in-1 grill?

Yes — the two included grids measure 17 1/16” x 11 1/16” each, which combine to a total footprint of 17 1/16” x 22 1/8” when placed side-by-side. They are produced specifically as replacements for the Pit Boss Memphis Ultimate 4-in-1 gas and charcoal combo grill with smoker. Always confirm your original grate dimensions before ordering to ensure a correct fit.

• Each grid: 17 1/16” x 11 1/16”.
• Total coverage when paired: 17 1/16” x 22 1/8”.
• Designed to match OEM spacing and placement in the Memphis Ultimate 4-in-1.

How durable and safe are these cast iron grates?

Hongso grates are cast from heavy-duty iron to withstand repeated high-heat cycles and resist warping better than thin stamped metal. They have passed SGS testing to meet or exceed applicable safety and material standards, and the raw material is non-toxic when properly seasoned. With routine care they can last for years and improve with seasoning rather than degrade quickly.

• Robust cast iron resists bending and holds shape under heat.
• SGS-tested materials for safety and non-toxicity.
• Improves with regular seasoning and proper cleaning care.

How should I maintain and season these grates?

Seasoning creates a natural nonstick layer and protects the cast iron from rust. Before first use, clean off any manufacturing residue, coat the grates thinly with high-smoke-point oil, and heat the grill until the oil polymerizes. After cooking, scrape off food debris, rinse when cool, dry fully, and periodically reapply oil to maintain the seasoned surface.

• Clean debris after each use, dry thoroughly to avoid rust.
• Season with vegetable or flaxseed oil by heating until polymerized.
• Store in a dry place or apply a light oil coat if unused for long periods.

Who is this for? Home grillers who own a Pit Boss Memphis Ultimate 4-in-1 gas and charcoal combo grill with smoker and want a long-lasting upgrade or replacement for worn factory grates. These Hongso cast iron grates suit cooks seeking better searing, improved heat retention, and durable construction that responds well to regular seasoning and care. Measure your original parts before purchasing to confirm fit and get ready for deeper sears and more consistent grilling results.
