About this product
🤝 New to Viaggo NZ — BOS Has Arrived
We're excited to partner with BOS, one of Australia's most trusted names in engineer-grade caravan hardware. Now available in New Zealand through Viaggo for the first time.
BOS 440-051 Stabiliser Legs are the heavy-duty upgrade for caravans currently on standard square legs. Heavy duty design allows you to level your caravan effortlessly with a cordless drill or manual handle as a backup. With 160mm of extended vertical travel, they're powerful enough to raise your caravan off the ground to change a flat tyre. The 500mm leg suits caravans that sit higher off the ground. Bolts straight into existing stabiliser mounting points — no modifications needed.
