Utheer Cast Iron Grill Grates for Pit Boss 820/850 – 2-Pack Heavy-Duty Pre-Seasoned Sear-Ready Replacement

Utheer’s two-pack heavy-duty cast iron grates are direct-fit replacements for Pit Boss 820 and 850 series pellet grills, designed to hold and distribute heat for superior searing and even cooking.

If your Pit Boss 820 or 850 series grates are warped, pitted, or failing to retain heat, these Utheer cast iron replacements restore consistent temperature and sear performance. Made from upgraded, thicker cast iron, they are engineered for long-term durability, better heat retention, and a safer, smoother edge profile. They arrive pre-seasoned or with a smooth, low-stick finish depending on batch, and require basic maintenance like regular cleaning and oiling to stay in peak condition.

Will these fit my Pit Boss 820 or 850 grill model?

Yes — these grates are manufactured to match the dimensions and mounting points for a broad range of Pit Boss 820 and 850 series models and compatible Navigator/Pro variants. Always measure your original grate before ordering to confirm exact fit.

• Compatible with Pit Boss 820 Series and Pro/850 Series models
• Works with PB820, PB820D, PB820XL, PB850PS2, PB850XL and similar model codes
• Sold as a 2-pack to replace both cooking surfaces or keep one as a spare

How do these grates improve searing and heat distribution?

Thicker cast iron stores and radiates heat more evenly across the cooking surface, producing sharper sear marks and reducing hot/cold spots. That consistent contact also helps lock juices and create a desirable crust on steaks and thicker cuts.

• Dense cast iron construction absorbs and retains high heat
• Even heat flow across the bars for consistent searing
• Smoother, rounded edges for safe handling and a professional finish

What maintenance do these cast iron grates need?

Cast iron requires routine care to prevent rust and preserve its nonstick properties: clean hot food residue after each use, dry thoroughly, and apply a light coating of cooking oil before storing. Proper care extends the life of the grates and improves performance over time.

• Scrape and brush after cooking, then wash off residue if needed
• Dry fully in sun or with heat to avoid moisture exposure
• Rub with a thin layer of oil to maintain seasoning and corrosion resistance

Are these grates safe and durable for frequent grilling?

Yes — the upgraded heavy-duty cast iron used in these grates is thicker and less brittle than standard cast parts, improving longevity and heat-holding ability while resisting corrosion when properly maintained. The smooth finish reduces food sticking and minimizes risk of cuts when handling.

• Upgraded thicker cast iron for added strength and durability
• Good corrosion resistance when cleaned and oiled regularly
• Designed with smooth edges for safer installation and removal

Who is this for: These Utheer grates are ideal for Pit Boss owners who want to replace worn factory grates, barbecue enthusiasts chasing better sears and heat retention, or anyone seeking a durable spare set for frequent outdoor cooking. They suit backyard grillers, weekend hosts, and small-scale caterers who need reliable, heavy-duty cast iron cooking surfaces that match Pit Boss 820/850 specifications.
