Weber Summit · Parts Guide
Flavorizer bar replacement is the most-commonly-needed Weber Summit maintenance task. Stainless steel Summit flavorizer bars typically last 8-12 years before warping, splitting, or developing rust spots that affect heat distribution. The fix costs $97-147 OEM (or $40-90 aftermarket) and takes 10 minutes — but ordering the wrong set is easy because Summit has four distinct configurations: 400 Series with or without smoker box, and 600 Series with or without smoker box. Each uses a different part number with different bar counts. This guide identifies your specific Summit configuration first, then connects you to the exact flavorizer bars for your grill.
This page completes the Summit commercial parts cluster — the Summit-specific deep dive on flavorizer bars. For the companion Summit guide, see our Weber Summit Burner Tubes guide.

The Basics
The angled stainless steel strips above your Summit burners are a patented Weber innovation. Three critical functions explained.
Angled bars deflect grease drippings away from gas ports underneath. This protection extends Summit burner tube lifespan from 6-8 years (without protection) to 10-15 years. Without flavorizer bars, grease would clog gas ports within months.
Grease drippings hitting hot bars vaporize and smoke — recirculating flavor up through food. Premium Summit flavorizer bars (heavier-gauge stainless than Spirit/Genesis) create more smoke vaporization than mid-tier flavorizer bars. The Weber smoky flavor that defines Summit cooking.
Bars spread heat across the cooking surface. The 45-degree V-shape redirects flame upward to create uniform temperature distribution. Summit's larger cooking area (4-burner 400 or 6-burner 600) makes even heat distribution especially important — flavorizer bars are what prevent hot spots above each burner.
When Summit flavorizer bars fail, all three functions degrade simultaneously. Burners get dirtier faster, food loses Weber smoky flavor, temperature distribution becomes uneven. Time to replace.
Diagnosis
Recognize the warning signs before they affect cooking performance.
The most common sign. Even premium Summit stainless flavorizer bars develop rust at metal fatigue points after 8-12 years. Once rust starts, it accelerates fast. Summit bars typically rust later than Spirit/Genesis bars due to heavier-gauge construction, but eventual rust is inevitable.
High-heat cycles cause metal fatigue. Visibly bent, split, or wavy bars don't distribute heat properly. Summit bars warp slightly less than Spirit/Genesis bars due to thicker construction, but eventually warping is normal — replacement window 1-2 cooking seasons after warping appears.
Uneven flame patterns or yellow spots on burner tubes after cooking indicate flavorizer bars have holes or gaps letting grease through. Summit's larger cooking area means more total grease drippings — bars work harder than smaller grills' bars.
If your Summit-cooked food tastes more "gas grill" and less "Weber smoky," the bars have lost their vaporization performance. Often the first symptom that's noticed before visible damage appears. Premium Summit flavorizer bars deliver the strongest Weber smoky character — losing it is dramatic.
Summit flavorizer bar lifespan: 8-12 years with normal use — typically longer than Spirit/Genesis bars due to premium construction. Covered grills last longer; coastal/humid climates reduce lifespan. Most Summit owners replace flavorizer bars 1-2 times during the grill's 15-20 year lifespan.
Step 1
Summit flavorizer bar quantities and dimensions vary by Summit Series (400 vs 600) AND by smoker box presence. Four distinct configurations exist — identify yours carefully.
2007 – 2023 (Most 400 Series)
Common models
2007 – 2016 (E-420 Base)
Common models
2007 – 2023 (Most 600 Series)
Common models
2007 – 2010 (E-620 Base)
Common models
Quick Summit identification rule: count your burners and check for smoker box. 4 burners + smoker box = Part #67668 (8 bars). 4 burners no smoker box = Part #67669 (9 bars). 6 burners + smoker box = Part #67670 (12 bars). 6 burners no smoker box = Part #67671 (13 bars). The smoker box is a separate compartment to one side of the main cooking area — easy to spot. Most 400 and 600 Series Summit grills DO have smoker boxes (the E-420 and E-620 base models are the exceptions). When in doubt, count your existing bars and measure one — should be 18" long.
Most Common Tier
Summit 600 Series — the flagship of the 2007-2023 Summit lineup. 6-burner premium gas grill, most common in current homes. Most current Summit owners have 600 Series grills with smoker boxes (Part #67670).
Official Weber stainless steel flavorizer bars for Summit 600 Series (2007-2023) WITH smoker box. Set of 12 bars, each 18.1" long x 1.8" wide x 1.3" tall. 16-gauge premium stainless construction. Fits Summit E-640, S-640, E-650, S-650, E-660, S-660, E-670, S-670.
Official Weber stainless flavorizer bars for Summit E-620, S-620 (2007-2010) base configurations without smoker boxes. Set of 13 bars, same 18.1" length as #67670 but different quantity (13 vs 12) due to no smoker box section.

4-Burner Summit
The 4-burner Summit 400 Series uses similar bar specifications to 600 Series but with fewer total bars. The smoker-box-or-not distinction matters here too.
Official Weber stainless flavorizer bars for Summit 400 Series (2007-2023) WITH smoker box. Set of 8 bars, each 18" long x 1.6" wide x 1.2" tall. Fits Summit E-440, S-440, E-450, S-450, E-460, S-460, E-470, S-470.
Official Weber stainless flavorizer bars for Summit E-420, S-420 (2007-2016) base configurations without smoker boxes. Set of 9 bars, same 18" length as #67668 but different quantity (9 vs 8).
304-stainless aftermarket flavorizer bars for Summit 400 Series. Available in 8-piece (with smoker box) or 9-piece (E-420 base) configurations. Brands: Stanbroil, Plowo, Zemibi, SafBbcue. Replaces Weber Part #67668 or #67669.
Important note for Summit 400 owners: even within the 400 Series, the smoker box determines the part number. E-420 and S-420 base models without smoker boxes use Part #67669 (9 bars). All other 400 Series models (440, 450, 460, 470) include smoker boxes and use Part #67668 (8 bars). Look for the smoker box compartment to one side of the main cooking area — present on most models, absent on E-420/S-420 base.
Pre-2000 and Post-2024
Summit grills outside the 2007-2023 era use different flavorizer bar specifications. Pre-2000 Summit had different mounting; current 2024+ Summit redesigned the entire system.
Stainless steel flavorizer bars for pre-2000 Summit grills. Configuration varies by exact model. Contact Weber at 1-800-446-1071 with serial number for exact part identification. grillparts.com also specializes in legacy Weber support.
Flavorizer bars for current Weber Summit Series (2024+ redesign). Updated specifications vs 2007-2023 Summit — NOT INTERCHANGEABLE with older Summit parts (#67670, #67671). Verify model and production year before ordering.
For all Summit grills outside the 2007-2023 standard era: Weber's "Find Parts" tool at weber.com/support is the most reliable resource. Enter your model number and serial number to see compatible parts. For grills under warranty, file claims with Weber first before purchasing retail replacement parts.
Material Choice
Unlike Spirit and Genesis, Summit doesn't offer porcelain-coated flavorizer bars. Premium tier means premium materials only.
Spirit and Genesis owners have a choice between stainless steel and porcelain-coated steel flavorizer bars at different price points. Summit owners don't have this choice — Weber sells Summit flavorizer bars exclusively in stainless steel, reflecting the premium tier's positioning.
This is actually good news for Summit owners:
The downside: stainless costs more than porcelain. Summit OEM bars run $97-160 vs Spirit OEM bars at $50-100. But Summit's stainless bars last 2-3x longer than Spirit/Genesis porcelain bars, making the per-year cost similar or better.
For Summit owners, the only material choice is between Weber OEM stainless ($97-160) and aftermarket stainless ($40-90). Aftermarket brands typically use the same 304-grade stainless as OEM, just at lower cost.
Buying Strategy
For flavorizer bars, aftermarket is often the smart choice. Here's when OEM is worth the premium for Summit specifically.
Manufactured by Weber to exact factory specifications. Perfect fit. Premium 16-gauge stainless construction. Preserves warranty on Summit grills under Weber's coverage. Direct customer service for installation questions.
Buy OEM when:
Third-party manufacturers (Stanbroil, SafBbcue, Tmozyar, Plowo, Zemibi, Dongftai) make bars dimensionally compatible with Weber Summit part numbers. 40-60% cheaper than OEM. Some include flame ventilation improvements.
Buy aftermarket when:
For Summit flavorizer bars specifically: aftermarket is genuinely good value on 10+ year old Summit grills. Like Spirit and Genesis flavorizer bars, these aren't gas-carrying parts — fit precision matters less than on burner tubes. Quality aftermarket bars match OEM performance at significantly lower cost. Save the OEM premium for current Summit grills still under warranty.
DIY Installation
One of the easiest Weber Summit repairs. No tools required. No gas disconnection needed. 10-15 minutes total (slightly longer than Spirit/Genesis due to more bars).
Turn off gas and let grill cool completely
Turn off gas at LP tank or NG supply. Let the grill cool fully — Summit's premium construction holds heat longer than Spirit/Genesis. Allow 45-60 minutes after turn-off before handling.
Remove cooking grates
Lift Summit cooking grates out (heavier than Spirit/Genesis grates). Set aside on clean surface. Cleaning them while you're at it is good habit.
Lift out old flavorizer bars
Old bars lift out of support brackets — no screws or hardware. Summit has more bars than Spirit/Genesis (8-13 vs 3-5), so this takes slightly longer. Dispose of old bars properly (grease residue may be present).
Clean the support brackets
Wipe away grease buildup, debris, or rust from the support brackets. Summit brackets are larger than Spirit/Genesis brackets — more surface area to clean. Clean brackets allow new bars to seat evenly.
Install new flavorizer bars
Place new bars into support brackets — angled edge faces DOWN (peaked side up). Each bar should sit flat. Wobbly bars indicate improper seating — lift and reseat. Summit's larger bar count (8-13) means more bars to position; take your time.
Reinstall cooking grates
Place grates back on top of bars. Verify grates sit flat.
Test light the grill
Reconnect gas. Light each burner individually. Check for uniform blue flame and even heat distribution. Heat the empty grill to 400°F for 10-15 minutes to burn off packaging residue from new bars before cooking food.
Avoid These
Mistakes that waste money on wrong parts.
The most common Summit ordering mistake. Summit 600 with smoker box uses 12 bars (#67670); Summit 600 WITHOUT smoker box uses 13 bars (#67671). Summit 400 with smoker box uses 8 bars (#67668); Summit 400 WITHOUT smoker box uses 9 bars (#67669). Always count your existing bars and verify smoker box presence before ordering. Wrong-quantity sets don't fit properly.
400 Series uses 18" bars; 600 Series uses 18.1" bars. Different part numbers (#67668/#67669 for 400 Series; #67670/#67671 for 600 Series). The half-inch length difference may not seem significant, but the bars are not interchangeable between Summit Series. Verify burner count: 4 burners = 400 Series; 6 burners = 600 Series.
The 2024 Summit redesign uses entirely different parts than 2007-2023 Summit despite sharing the brand name. Current Summit has 5 burners at 13,000 BTU each (vs older 6 at 10,000 BTU) and updated flavorizer bar specifications. Always verify production year before ordering — pre-2024 vs 2024+ Summit are essentially different products.
Traditional wire grill brushes can shed metal bristles during cleaning. Bristles stuck to new flavorizer bars can fall into burner tubes, creating hot spots and uneven flame. Switch to bristle-free brushes (Grill Rescue, GrillArt, nylon) for cleaning around new flavorizer bars.
If 3 of 12 bars look badly rusted and 9 look "okay," replace all 12. Mixing old and new bars means uneven cookbox performance AND the older bars will fail within 12-18 months anyway. Full-set replacement saves a second repair trip and ensures consistent performance.
