Grill Grates for Charbroil Performance 4 Burner - Heavy Cast Iron Fit

In this review of the Uniflasy replacement grill grates for Charbroil Performance 4 burner and compatible models, the bottom line is simple: these heavy cast iron grates are for owners who need a direct, durable replacement that restores searing ability and reduces flare-ups. The set arrives as three pieces (two smaller, one larger) and is designed to fit a long list of Charbroil Performance, Advantage, Designer, Commercial and Gourmet Infrared models, so the biggest reason to buy is compatibility combined with the heat retention of cast iron for better sear marks.

Key Features

• Model compatibility: Fits a wide range of Charbroil Performance and related models so users can replace worn grids without replacing the whole grill.
• Three-piece package: Includes two smaller grates and one larger grate to match the original layout for straightforward installation.
• Heavy cast iron construction: Retains heat well to deliver pronounced sear marks and more even cooking across the surface.
• Flare-up reduction: The solid cast iron bars help reduce flare-ups compared with thin or warped OEM grates, improving control when grilling fatty foods.
• Broad cross-brand fit: Works with many related units and replacement part numbers so it can serve as a substitute for several original parts.

Who It's For

This set is ideal for homeowners who own a Charbroil Performance 4 burner or one of the compatible Charbroil series listed and want a rugged replacement that restores searing performance. It is also a good choice for grill owners who prefer the heat retention and marks produced by cast iron over lighter stainless or porcelain-coated grids.

It is less suitable for users who want enamel-coated or stainless surfaces that require less maintenance against rust; cast iron benefits from seasoning and occasional care. Also, buyers who need a single custom-sized grate should verify fit against their model numbers before purchasing.

Pros & Cons

Pros

• Solid cast iron delivers superior heat retention and visible sear marks on meat and vegetables.
• Replaces multiple Charbroil part numbers and fits many Performance and Advantage models for broad compatibility.
• Three-piece set mirrors original layout, making installation straightforward and cost-effective compared with replacing the whole grill.
• Customers report reduced flare-ups and good build quality for the price, representing strong value.

Cons

• Cast iron requires occasional seasoning and care to prevent rust, so it needs more maintenance than coated grates.
• A few customers noted slight size differences in individual cases, so buyers should confirm model fit before relying on exact OEM alignment.
