Charbroil Grill Grates Replacement Set - Cast Iron 3-Piece

In this review of the Charbroil Grill Grates replacement set the bottom line is simple: this 3-piece cast iron kit is for owners of Charbroil Performance 4, 5 and 475 series grills who need a sturdy, heat-retaining replacement that matches original grate layouts. The reviewer found the set installs easily, produces good sear marks and restores the look of an older grill. It suits cooks who want heavy cast iron grates that hold heat well and are compatible with many Charbroil model numbers.

Key Features

• Compatibility: Fits a long list of Charbroil Performance 4 and 5 burner models and original cooking grate model numbers so buyers can replace worn grates without modifying the cookbox.
• Three-piece pack: Includes two larger 18 x 9 1/4 in grates and one 18 x 6 1/2 in narrow grate, matching original footprint and simplifying installation.
• Cast iron construction: Thickened cast iron distributes heat evenly and retains temperature for better searing and consistent cooking across the grill surface.
• Easy to season: The grates accept oil seasoning well, which builds a natural nonstick surface and helps protect against sticking and wear.
• Durable finish: Solid cast iron resists scratching under normal use and gives the grill a refreshed, factory-like appearance.
• Replacement confidence: Sold as a set sized to match common Charbroil part numbers so users can replace all primary cooking grates at once.

Who It's For

This replacement grate set is ideal for Charbroil Performance grill owners who need a like-for-like swap for factory grates, especially those with models in the 46334x and 46337x ranges and original model numbers like G470-0002-W1. It is also a good choice for home cooks who prioritize strong heat retention and want the classic cast iron sear.

It is not for users who prefer lightweight porcelain-coated steel grates or who want a ready-made nonstick surface without seasoning. If you need corrosion-proof stainless steel or an entirely different grate geometry, look elsewhere.

Pros & Cons
