48KG Extension Kit for Adjustable Kettlebell - Wildman Poison Pill
The best adjustable kettlebell just got better. Designed in collaboration with kettlebell mastermind Mark Wildman, this expansion transforms your existing 12–32kg Adjustable Kettlebell into a monstrous 12–48kg Adjustable Kettlebell Set. That’s right: over 100lbs in one kettlebell.
But fair warning: this bad boy isn’t for beginners or classes. It’s made for heavy hitters who’ve already tamed their current setup and are hungry for more. As you load more plates, the bell gets longer (yes, physically), making it less snatch-and-clean friendly, but perfect for grinds, swings, and farmer carries that’ll light your soul—and forearms—on fire.
Kettlebell not included—this is an expansion pack only!
What’s Included:
- Four (4) × 4kg black powder-coated cast iron plates
- Four (4) extender bolts (1 per increment level)
- One (1) all-in-one wrench for torque-tightening wizardry
- One (1) short bolt for 1-plate setups
- One (1) extra nut
IMPORTANT: You MUST tighten the extension bolt before every use. This expansion pack is compatible with the 12–32kg Adjustable Kettlebell (Bells of Steel or Mark Wildman editions). It’s not compatible with the 6–12kg Adjustable Kettlebell or Plastic Bottom, and while it might fit other brands with similar molds, we can’t guarantee it. We do not recommend expansions for classes or quick transitions as changing weights takes 1-2 minutes.
