Sizing Recommendations (Note: You must match the upgrade kit size to your existing Gen4 Chest Protector (VR1–VR4). The chest protector and vest kit share sizing codes to ensure correct fit):

|---|---|---|---|
| Kid Kart | VR1 | 22″–27″ | 5–8 years |
| Junior | VR2 | 26″–31″ | 8–12 years |
| Junior II | VR3 | 30″–35″ | 12–14 years |
| Medium | VR4 | 34″–39″ | 14+ years / Small adult |
Unlock full torso protection with the Valhalla Gen4 Armadillo Chest‑to‑Vest Upgrade Kit — the smart way to adapt your existing Gen4 Chest Protector into a full‑coverage vest. Designed for youth motorsports such as karting, motocross and BMX, this kit adds the missing side, rib and back panels plus secure fastenings to elevate the chest‑only protector into a vest format. That means your young driver gets front, side and rear protection without buying an entirely new vest.
The upgrade kit is ideal when your program or track mandates full‑torso protection, when your driver has grown and you need better fit‑and‑coverage, or when you want modular gear that evolves with your racing season. Because the kit uses the same base chest piece, installation is straightforward and fit remains adjustable via side straps and buckles. For parent‑coaches and kart team managers, this means reduced gear cost, less replacement cycle and improved value.
Keep in mind: this kit is not standalone — you must already own the Gen4 Armadillo Chest Protector (sold separately). Once fitted, ensure all straps are snug, back panel aligned correctly and that any side panels do not impede seat or harness movement. With proper installation and size selection you’ll have a flexible system: start with chest‑only protection for kart events, then add the upgrade kit when advancing into full‑vest rules or more demanding use.
