E-310 flavorizers are a five-bar, 15.3-inch set (OEM 7636 family) on front-control 2013+ carts. E-210 uses three wider bars of the same length. Count is the first filter; a 210 kit leaves two port rows naked on a 310.
Side-control Spirit 300 (2007–2012) is often 21.5” / 7536. Measure. Plate.
When they are done
- Daylight in the peak over a burner.
- Ends crumbled out of the notches.
- Warped so the bar no longer sits.
- Intact but filthy → degrease, do not throw them yet.
Measure and swap
- Cold. Grates off. Count five bars over three tubes.
- Measure end-to-end. Write 15.3” versus 21.5” versus Genesis 17”.
- Compare the verified 7636 listing above to your tape. Forum numbers are clues, not a serial guarantee.
- Gloves. Lift old bars. Scrape the notches level.
- Set new bars with each peak over a tube. From the front you should not see a port row in a valley.
- Grates on. Preheat and look once.
