What parts are included and what are their sizes?

This replacement package supplies the most-worn grill components so you can quickly restore cooking performance. Each component is sized to match original equipment dimensions for an easy swap.

• Seven porcelain-coated steel flavorizer bars — 17-1/8" L x 2-1/8" W x 2-1/8" H each for even heat distribution and grease management.
• Four stainless steel burners — 19-3/4" long, built to resist corrosion and deliver consistent flame output.
• Four heat deflectors (drip pans) — 12-1/2" x 4-1/4" to protect the combustion area and channel drippings away.

How durable and high-quality are the replacement components?

AJinTeby uses porcelain-coated steel for the flavorizer bars and stainless steel for the burners to balance heat performance with corrosion resistance. These materials are chosen to withstand repeated heating cycles and outdoor exposure better than untreated metals.

• Porcelain coating reduces sticking and provides a smooth, easy-to-clean surface for the flavorizer bars.
• Stainless-steel burners resist rust and maintain consistent gas flow under high heat.
• Heat deflectors shield burners from drips and help stabilize internal grill temperatures.

How difficult is installation and maintenance?

Installation is designed to be fast and straightforward so you can return to grilling with minimal downtime. Basic hand tools are typically all that’s required, and each piece replaces the original part without modification.

• Average install time: a few minutes per component for most homeowners familiar with grill maintenance.
• Smooth, porcelain surfaces on the flavorizer bars make wiping away grease easier than bare steel.
• Periodic visual inspection and routine cleaning extend the life of all parts.

Who is this kit for? Grill owners who want to extend the life of their Weber GS4 Genesis II 400 Series grill without buying a full new unit will find this AJinTeby kit ideal. It’s aimed at DIY-minded homeowners, seasonal grillers, and anyone performing an off-season refresh to restore even heating, reduce flare-ups, and improve overall cooking reliability. If you need a direct-fit replacement for worn flavorizer bars, burners, or heat deflectors and want materials chosen for rust resistance and heat tolerance, this kit meets those needs.
