Leship Cast-Iron Grill Grates for Weber Spirit & Genesis 17.5" x 11.9" Pair — Heavy Duty Heat Retention, Better Sear

If your Weber grill’s original grates are rusted, warped or no longer searing evenly, the Leship replacement pair offers a sturdy, high-heat cooking surface built to bring back consistent grilling. Each grate measures 17.5" x 11.9" (two pieces together 17.5" x 23.8"), made from heavy cast iron to lock in heat, create pronounced sear marks and stand up to repeated use. These grates are designed to directly replace multiple OEM part numbers (for example Weber 7638, 7639 and others) and fit numerous Spirit and Genesis series grills—double-check your model before ordering.

Which Weber grill models will these Leship grates fit?

They are compatible with many Weber Spirit 300 Series and Spirit II GS4 E/S-310 and related SP models, plus a wide range of Genesis models from older series. Fitment includes Spirit E310, E315, S310, S320, S330 and several Genesis Silver, Gold, Platinum and 1000–3500 series grills, as listed by the manufacturer. Always compare the grate dimensions and your grill’s original part number to confirm fit.

• Compatible Spirit models: E310, E315, S310, S320, S330, and related 300/700/900 series.
• Compatible Genesis models: Genesis I–IV, 1000–3500, Silver/Gold/Platinum B/C series (2000–2010).
• Replaces OEM numbers: 7638, 7639, 7525, 65906, 7011, 7012, 7526, 7527.
• Also fits certain Weber Smokefire Ex4/Ex6 pellet grills.

How do these grates affect cooking performance?

Cast iron excels at holding and radiating heat, so these grates deliver improved sear lines and steadier surface temperatures compared with many thin factory grids. They help the searing process by maintaining high, even contact heat under food and can improve crust formation on steaks, chops and vegetables. Proper seasoning and care will enhance nonstick behavior over time.

• Heavy cast iron material for superior heat retention.
• Produces clear sear marks for better flavor development.
• Two-piece set covers standard cooking area when used together.
• Seasonable surface becomes more nonstick with use.

What should I know about installation and maintenance?

Installation is straightforward: remove your old grates and drop the new Leship pieces into the grate supports—no tools required for most grill beds. To preserve the grates and prevent rust, season them before first use and dry/coat them after cleaning. Avoid harsh detergents or soaking long-term; use a stiff brush and light oiling to maintain the surface.

• Measure current grates to confirm 17.5 x 11.9 inch fit for each piece.
• Season with cooking oil before first high-heat use.
• Clean with a stiff brush; dry and oil after washing to prevent rust.
• Avoid soaking in water or using corrosive cleaners.

Will these grates replace the original Weber parts exactly?

Leship lists these grates as direct replacements for several Weber part numbers and compatible model numbers, but grill designs and production years vary. If your grill used any of the listed OEM numbers or matches the stated model names and grate measurements, these should work as a direct swap—confirm dimensions and grill layout first to ensure perfect alignment.

• Replacement for Weber 7638, 7639 and other listed numbers.
• Cross-check with your grill serial/model number and original grate size.
• Fits many Spirit II GS4 models but not all Genesis II LX variants.
• Contact seller with images if fitment is uncertain.

Who is this for: These Leship cast-iron grates are intended for grill owners who need a durable replacement to restore searing performance on Weber Spirit and many Genesis models, or for anyone upgrading thin factory grates to a heavier, heat-retaining surface. They suit frequent grillers who will season and maintain cast iron regularly and who want a cost-effective way to revive an older grill without buying a new unit.
