Utheer Cast Iron Grill Grate for Pit Boss 820 850 Series - Heavy-Duty

In this review of the Utheer cast iron grill grate set, the bottom line is simple: these replacement grates are for owners of Pit Boss 820 and 850 series pellet grills who want heavier, searing-ready cooking surfaces without paying dealer prices. They arrive as a two-pack of upgraded heavy-duty cast iron that fits the listed Pit Boss and Navigator models, and the most convincing reason to buy is the material: cast iron that retains heat, gives robust sear marks and feels noticeably sturdier than thin stamped replacements.

Key Features

• Package: Supplied as a set of two grates so buyers replace both side-by-side cooking surfaces at once for consistent heat and appearance.
• Compatibility: Designed to fit Pit Boss 820 and Pro Series 850 grills and several model variants, simplifying part replacement for those exact models.
• Material quality: Made from upgraded heavy-duty cast iron that is heavier and less brittle than inexpensive alternatives, improving longevity and heat retention.
• Heat retention: The cast iron construction holds and distributes heat evenly, which helps achieve professional searing on steaks and burgers.
• Safety and finish: Smooth edges and a well-finished surface reduce the risk of cuts during handling and make the grates easier to clean after cooking.
• Maintenance: Surface is non-stick when properly seasoned, and cleaning is straightforward by removing residue and drying in sun to prevent rust.

Who It's For

This set is best for Pit Boss 820 and 850 series owners, including Pro Series II and Navigator 850 users, who need a direct-fit replacement and want the benefits of cast iron searing and heat retention. It suits backyard grillers who cook steaks, chops and burgers and who prefer a heavier, more substantial grate over thin factory parts.

Those who should look elsewhere include owners of grills outside the listed models or buyers who need enameled or stainless options for low-maintenance care; this set is raw cast iron and requires basic maintenance like drying and seasoning to prevent corrosion.
