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.\u003c\/p\u003e\n\n\u003ch3\u003eWhich Weber grill models will these Leship grates fit?\u003c\/h3\u003e\n\u003cp\u003eThey 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.

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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHeavy cast iron material for superior heat retention.\u003c\/li\u003e\n  \u003cli\u003eProduces clear sear marks for better flavor development.\u003c\/li\u003e\n  \u003cli\u003eTwo-piece set covers standard cooking area when used together.\u003c\/li\u003e\n  \u003cli\u003eSeasonable surface becomes more nonstick with use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat should I know about installation and maintenance?\u003c\/h3\u003e\n\u003cp\u003eInstallation 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasure current grates to confirm 17.5 x 11.9 inch fit for each piece.\u003c\/li\u003e\n  \u003cli\u003eSeason with cooking oil before first high-heat use.\u003c\/li\u003e\n  \u003cli\u003eClean with a stiff brush; dry and oil after washing to prevent rust.\u003c\/li\u003e\n  \u003cli\u003eAvoid soaking in water or using corrosive cleaners.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these grates replace the original Weber parts exactly?\u003c\/h3\u003e\n\u003cp\u003eLeship 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReplacement for Weber 7638, 7639 and other listed numbers.\u003c\/li\u003e\n  \u003cli\u003eCross-check with your grill serial\/model number and original grate size.\u003c\/li\u003e\n  \u003cli\u003eFits many Spirit II GS4 models but not all Genesis II LX variants.\u003c\/li\u003e\n  \u003cli\u003eContact seller with images if fitment is uncertain.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho 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.
