Grill Parts for Weber Spirit e310 17.5in Cast Iron Grill Grates

In this review of the Grill Parts for Weber Spirit e310 cast iron grates, the bottom line is simple: these are for grill owners who want a heavier, better-searing replacement for worn factory cooking grates. They are engineered to match multiple Weber Spirit 300 and Spirit II 300 variants and many older Genesis and SmokeFire models, so they work well as a direct swap for users who need reliable heat retention and strong searing performance. The single biggest reason to buy is the solid cast iron construction that improves heat consistency and marks food far better than thin stainless bars.

Key Features

• Precise fit: Designed to replace Weber parts #7638, 7525, 7527, 65619 and 65906 so installation is straightforward for compatible Spirit and Genesis models.
• Cast iron construction: Solid cast iron provides superior heat retention and creates better sear marks compared with lighter grate styles.
• Wide compatibility: Fits Spirit 300 series, Spirit 700, Spirit II/GS4 variants and several Genesis models, making these grates a flexible replacement option.
• Durable finish: Heavy-duty build reduces the risk of chipping common to enamel-coated alternatives and stands up to frequent use.
• Size matched: Each grate measures about 17.5in x 11.9in, delivering a full 17.5in x 23.8in cooking area for three-burner Spirit setups.

Who It's For

These cast iron grates are best for home cooks and weekend grillers who own a compatible Weber Spirit 300 series or listed Genesis model and want improved searing and heat retention. They suit people who do a lot of high-heat cooking such as steaks and vegetables, where a heavy grate helps lock in juices and create distinct grill marks.

Grillers who prefer low-maintenance stainless steel or who own incompatible Genesis versions (for example, some Genesis II LX variants or Genesis Silver A) should look elsewhere. Also, buyers who want a fully rust-proof, maintenance-free option may prefer stainless steel over cast iron.

Pros & Cons

Pros

• Excellent heat retention and searing thanks to heavy cast iron construction.
• Fits a wide range of Spirit 300 and Spirit II grills and replaces common Weber part numbers for a direct swap.
• Solid, heavy build that many customers prefer over thin factory grates and that feels durable in use.

Cons

• Cast iron requires regular seasoning and can rust if not maintained, which some users reported.
• Not compatible with all Genesis models, so double-check model fit before purchasing.
