Replacement GrillGrate Set for Weber Spirit 300 Series Gas Grill

GrillGrates with the GrateTool are the ultimate upgrade to your Weber Spirit 300 Series.  GrillGrates are reversible interlocking panels, giving you two grilling surfaces; rails up or on the flat side. GrillGrates tame flare-ups and even out the hot and cool spots common with all gas grills. This gives you even, stable temperatures across the cooking surface. This set is a drop-in replacement for the stock Spirit 300 Series grates. Constructed from hard anodized aluminum, GrillGrates will never rust. Made in the USA. The GrateTool is made in China.

  • Set Includes: (4) 17.375” GrillGrate panels and (1) 17.375” Gap Panel
  • Assembled dimensions = 17.375” deep x 22.5” wide
  • Designed for Weber Spirit 300 Series and older Weber Genesis® Grills pre 2007
  • Includes GrateTool and User Guide

PLEASE NOTE: If using this set on a new model Spirit, you will experience about a 2″ gap. We recommend either centering the set to have a slight gap on either side or separating your grates in the middle for two-zone grilling.

    Grates are great setup with one side flat and one not. Does cook hotter.but puts nice crust on hamburger (flat side).

  3. Colorado Caveman

    Just stop reading and buy them. Greater heat retention, much more even heating, seriously a game changer for your grill.

  4. Derrell Hickman

    Great upgrade, saved me from replacing whole grill. No more flare ups period

  5. Bob

    Easy to install, love that I can leave one side as flat side up for burgers and other side with raised searing fins. Does get hotter and cooks faster.

  6. William Frawley

    Wish I had these years ago. Fantastic grilling experience.

  7. Bryan Canty

    The grates worked as expected – AWESOME! I have them on EVERY grill I own. Can’t imagine not using them.

  8. Roger Neri

    Outfucking standing. Love it

  9. Ty York

    Love em

  10. Randy W Williams

    Bought these on a whim to replace the original grates that were still fine, but the bottom of the grill continued to flare up and burn anything that wasn’t cooked on super slow. Put these on and got great results almost immediately. Saved me having to buy a whole new grill.
    Great point about grease and debris. On well loved grills, do clean out the bottom of your grill under the grates. You will be surprised how much fire starter builds up there. With GG in place much of the debris will stay up top in the valleys. We suggest brushing debris to the back and letting it build up at the back of your grill. Once a month or so just lift out your GrillGrates and deposit the debris in the garden or garbage. You will be surprised how clean your grill will stay. #GrillGrateful #GrillOn

    These grates are simply awesome. One thing you won’t be happy with is when it comes time to flip them from flat side to raised side. It is a holy mess. It is often that I want to use both at the same time or flip them. It is such a messy pain that I ordered another set and bought a second Weber grill. Now I am totally happy.
    Brad here- The Scraper Tool will make quick work of the flat side and have it ready to grill in a few passes. I always have at least one panel flipped over to the flat side for a final hard sear. #grillgrateful

    I had read the reviews on these and was feeling worried after I clicked “purchase”. After grilling on them for a couple months I can say the hype is justified. These grates are a game changer. Your heat will be more even, your sear marks will be second to none, and the flavor you get is a marked improvement over the standard grates. Don’t be afraid of having a little gap if they don’t cover 100% of your grill. The airflow is helpful in regulating temps and I never feel like I’ve lost any noticeable amount of space.

    These are a bit pricey but if you have the money you need to do yourself the favor of buying these grates.
