If you already own a Weber kettle, you’re sitting on one of the most versatile charcoal grills ever made. But with the right upgrades, you can unlock even more performance, control, and versatility — without replacing your grill.
In this guide, we’ll break down the best Weber kettle upgrades from Spider and explain exactly what each accessory unlocks — from precision temperature control to multi-zone cooking and serious durability improvements.
Whether you’re focused on low-and-slow BBQ, high-heat searing, or weeknight grilling, here’s how to level up your Weber kettle.
Why Upgrade Your Weber Kettle?
The classic kettle grill is simple, durable, and capable. But out of the box, it has limitations:
- Manual airflow control
- Limited cooking zones
- No temperature automation
- Minimal prep space
Spider accessories are designed to remove those barriers — making charcoal cooking more accessible, more precise, and more powerful.

This is where to start.
1. Venom™ Temperature Controller
Unlock precision charcoal control
What It Does
The Venom™ transforms your Weber kettle into a digitally controlled charcoal system. Simply light your charcoal, set your desired temperature, and let the fan and controller maintain steady heat automatically.
What It Unlocks
- True low-and-slow smoking (225°F–275°F)
- Long brisket or pork shoulder cooks without babysitting vents
- More stable temperature control than manual vent adjustments
- Repeatable results
Why It Matters
Charcoal cooking doesn’t have to be intimidating. A temperature controller removes guesswork and makes your kettle perform more like a premium smoker — while still allowing high-heat grilling when you want it.
Best for: Backyard BBQ enthusiasts, brisket cooks, anyone frustrated by temperature swings.

2. Kettle Cart
Upgrade stability, storage, and workspace
What It Does
The Spider Kettle Cart replaces the basic tripod stand with a heavy-duty, stable cart system designed for real cooking sessions.
What It Unlocks
- Expanded prep space
- Better mobility
- Storage for tools, charcoal, and accessories
- A more permanent backyard setup
Why It Matters
A standard kettle is portable — but not always practical for larger cooks. A cart turns your kettle into a full backyard cooking station.
Best for: Frequent grillers, backyard entertainers, anyone tired of balancing trays on a side table.

3. Webcraft™ Cooking System
Turn your kettle into a multi-zone powerhouse
What It Does
Webcraft™ is a modular cooking system that adds multi-level cooking surfaces and heat control components inside your Weber kettle. Plus, unlock all compatible Huntsman™ accessories with the Webcraft.
What It Unlocks
- Two-zone cooking (direct + indirect heat)
- Simultaneous high-heat searing and low-and-slow smoking
- Ceramic heat deflector capability
- Increased cooking capacity
- Rotisserie and side shelf attachments
Why It Matters
Most kettle owners don’t realize how much versatility they’re missing. With the right internal system, your grill becomes a hybrid — capable of steakhouse searing and true BBQ smoking.
Best for: Grillers who want kamado-style flexibility from their Weber kettle.
