Spirit Grill Replacement Parts 7638 Grates & 7636 Flavorizer Bars

In this review of the Spirit Grill Replacement Parts set, the bottom line is simple: this kit is for owners of Weber Spirit 300 and Spirit II 300 series grills (front control models from 2013 on) who want heavier, longer-lasting cooking grates and replacement flavorizer bars that restore performance and appearance. The reviewer found the combination of two matte enamel cast iron grates and five porcelain steel flavorizer bars delivers better searing and more even heat than thin porcelain-coated grates, and it is a straightforward swap for compatible Spirit models.

Key Features

• Matte enamel cast iron grates: provide high heat retention and sear foods quickly for clearer grill marks and faster cook times.
• Heavier solid rods: thicker rods resist warping and give a sturdier cooking surface than many stock grates.
• Five porcelain steel flavorizer bars: protect burners, add smoky flavor, and promote even heat distribution across the cookbox.
• Easy to clean surfaces: non-porous porcelain and glossy heat tents wipe clean and avoid trapped residue when maintained.
• Direct compatibility: fits Spirit 300 and Spirit II 300 series front-control grills from 2013 and newer for a drop-in replacement.

Who It's For

This set is best for owners of Weber Spirit E-310, E-320, E-330 and the S/SP/II variants from model year 2013 onward who need a like-for-like replacement or want a more robust grate for searing. It suits backyard cooks who value heat retention and a heavy-duty cooking surface for steaks, burgers and cast-iron-friendly recipes.

Those who should look elsewhere include owners of Spirit models with side controls from older model years (2007-2012) and people who insist on stainless steel grates or completely different grate shapes. Also, if you prefer a lighter, non-cast-iron surface that requires no seasoning, consider alternate grate materials.

Pros & Cons

Pros

• Thicker matte enamel cast iron grates deliver superior heat retention and searing performance.
• Porcelain steel flavorizer bars reduce flare-ups and help distribute heat evenly across the grill.
• Replacement parts fit Spirit 300 series front-control models for a simple installation and improved appearance.

Cons

• Durability has mixed feedback from customers; some report the parts wear faster than expected under heavy use.
• Not compatible with Spirit grills that have side-mounted controls from earlier model years.
