GasSaf Cast Iron Grill Grates for Weber Spirit & Genesis 17.5x11.9 in (Pack of 2) — Heavy-Duty, High Heat Retention

GasSaf 7638 cast iron grill grates are a two-piece aftermarket replacement designed to match the fit and cooking performance of Weber Spirit and many Genesis series grills.

These heavy-duty, 17.5 x 11.9 inch cast iron grates (sold as a pack of two) are intended as direct-fit replacements for a long list of Weber part numbers and models, bringing back heat retention, searing performance and durable non-stick surfaces to aging grills. They’re made from solid cast iron to maintain steady cooking temperatures and recreate those classic barbecue grill marks while fitting a wide range of Spirit and Genesis units from the manufacturer’s older and newer lines.

Will these grates fit my Weber Spirit or Genesis grill?

GasSaf lists this set as compatible with many Weber Spirit 300 series models (E310, E320, E330, S310, S320, S330), Spirit 700, Weber 900 and a range of Genesis models including Silver, Gold and Platinum configurations. The pack replaces Weber part numbers 7638/7639 and fits numerous OEM model codes.

• Each grate measures 17.5 x 11.9 inches; two pieces cover 17.5 x 23.8 inches total.
• Compatible with Spirit 300 series, Spirit 700, Weber 900, Genesis 1000–3500, and many Gold/Silver/Platinum variants.
• Check your original grate dimensions and shape against these dimensions before ordering.

How does cast iron benefit my grilling?

Cast iron excels at storing and radiating heat evenly, which helps produce even searing and consistent cook temperatures for steaks, burgers and vegetables. The material’s density also yields pronounced grill marks and a natural non-stick surface if seasoned and maintained properly.

• High heat retention for steady searing and browning.
• Durable, heavy-duty construction resists warping under grill temperatures.
• When seasoned, cast iron develops a non-stick patina that improves with use.

How easy are these grates to install and clean?

Installation is straightforward: the two-piece set drops into most compatible Weber and Genesis grate supports without tools. Cleaning is easier than many expect—wipe and brush after each use, and re-season occasionally to maintain the non-stick surface and prevent rust.

• Tool-free installation for most compatible Weber/Genesis models.
• Brush off food debris after cooling; oil lightly to protect cast iron.
• Can be used on gas, electric or charcoal cookers that accept the size and shape.

Are these aftermarket grates reliable compared to OEM parts?

As aftermarket replacements, GasSaf grates offer comparable materials and function to original Weber parts but may differ slightly in finish or tolerances. They are engineered to deliver the primary benefits of OEM cast iron grates—heat retention, durability and searing—while providing a cost-effective option for restoring grill performance.

• Aftermarket product—verify fit by measuring your original grates.
• Constructed from cast iron for long service life when cared for properly.
• Sold as a two-piece set to replace both halves of compatible grate arrangements.

Who is this for: GasSaf 7638 cast iron grates suit grill owners who want to revive the cooking performance of older Weber Spirit or Genesis units without paying OEM prices. Ideal for homeowners who value strong heat retention and searing capability, this set is also a practical choice for hobbyists who maintain and season cast iron and for anyone replacing broken or heavily worn grill grates. Before purchasing, match the 17.5 x 11.9 inch dimensions to your original grates to ensure a correct fit.
